LiFE BATTERY SAFETY: This new product design is based on Lithium Iron Phosphate battery
chemistry......also known as “LiFEPO4”. LiFEPO4 cells offer high capacity in a lightweight package
similar to Lithium Polymer or Lithium-Ion cells, but with one big improvement. LiFEPO4 chemistry
is much more inherently safe as it does not suffer from temperature runaway conditions likeolder lithium chemistries do. The older lithium batteries were prone to fire if physically damaged
or short circuited. These new LiFEPO4 batteries have proven to be a much safer alternative.
While this battery chemistry is considered to be very safe, the TSA (Transportation Safety
Authority) has not yet made the distinction between these LiFEPO4 lithium cells and the older
less safe Lithium technologies. Please read and understand all transportation regulations before
shipping these batteries on public airlines. You can get a full, detailed explanation of theseregulations at the TSA website:
http://safetravel.dot.gov/whats_new_batteries.html
Additional information concerning “Larger Batteries” that applies to this product can be foundhere: http://safetravel.dot.gov/larger_batt.html Never ship your PSC Baby Zeus if it has been
physically or electrically damaged.
AC POWER SAFETY:All AC powered devices should be treated with proper caution and respect. AC power on film
sets and on locations may not always be properly grounded and/or distributed. PSC highly
recommends that you purchase and use an AC power tester prior to plugging in your PSC Baby
Zeus or any other AC powered device while on location. You can purchase simple to use,
inexpensive AC testers for less than $20. They are a simple plug that has 3 or 4 lights on the rearof the plug. These lights indicate good AC, proper grounding, etc. They can also indicate
dangerous AC conditions such as Hot and Neutral reversed or missing grounds. These AC testers
can be purchased at most electronics stores. Here is an example of a typical AC Tester. PSC does
not recommend any specific brand or take responsibility for its use or performance.

Typical AC Tester of the type you should use before plugging into AC on a film set or location.

FRONT PANEL:The front panel of the PSC BABY ZEUS contains eight (8) DC power output connections on 4 pin
female XLR’s. A SpeakOn connector used to connect the unit to an external battery (PSC Pelican
LiFE Battery). A 5-pin female XLR used to connect the BABY ZEUS Remote Control. An AC
indicating BLUE LED. A Multi Colored LED “Fuel Gauge” to indicate battery charge level. Power“ON” and “OFF” push button switches (delayed action for “OFF” switch). AC Input Connector.

AC CONNECTION: On the front panel of the Baby Zeus you will find the AC power connection.
This connection accepts a standard IEC power cord. You will also notice that as part of the AC
receptacle there is a built fuse holder that holds the AC protection fuse. This unit uses a 250v,
15 Amp, slow blow, 5 x 20mm fuse. A spare fuse is included inside the fuse holder drawer.

AC input with fuse holder

RACK MOUNTING: Your new Baby Zeus is designed to be rack mounted. It comes with a pairof heavy duty rack mount brackets. These brackets can be used from the front of the unit or therear of the unit. The brackets are designed to allow flush mounting of the Baby Zeus to the rackrails or recessed mounting allowing room for the XLR power connectors to not stick out beyond
the rack rails. The screws for installing these brackets are included. Please only use 6-32 x 0.375”
screws with this Baby Zeus. The use of longer screws may cause internal damage to the unit.

HEAT DISSIPATION: The PSC Baby Zeus uses a special, slow speed, low noise fan to provide
proper system cooling. This properly engineered cooling system uses linear air flow cooling topull heat away from the unit’s power supply. Over time, the fan grill and internal electronic
components will build up a layer or dust and dirt. This happens faster in dusty environments.
PSC recommends that you blow the dust out of the unit using compressed air from time to time
to keep the unit clean and cool running. You must leave open space above and to the rear of
the PSC Baby Zeus for proper cooling to take place. Likewise, this product should not be used infully enclosed rack case or other enclosures that limit air flow. Failure to provide proper
ventilation can and will damage the unit and will void your warranty.

DC CONNECTIONS: There are eight (8) XLR female DC output connectors located on the front
panel of the Baby Zeus. Seven (7) of the XLRs are rated for 3 Amps of output current. The
remaining one (1) output connector is rated for 6 Amps of output current. Each connector isindividually Poly Fuse protected and filtered so as to deliver clean, reliable power. If you ever
have any questions about this, please do not hesitate to call PSC and ask to speak with our service
technician. We are always available to help you in any way needed. Pin outs are industry
standard. Pin 1 is Ground and Pin 4 is Positive (+).

Seven (7) Output Connectors @ 3 Amps

One (1) Output Connectors @ 6 Amps

POWER SWITCHES: There are two round, momentary push button switches used to turn theunit on and off. The GREEN “ON” push button switch is used to turn the unit on. The RED “OFF”
push button is used to turn the unit off. Please note that the RED “OFF” push button switch isequipped with a time delay circuit. You must press and hold this push button switch for 3-4
seconds before the unit will shut off. This time delay function serves to keep you from
accidentally shutting down the PSC Baby Zeus unexpectedly while working.

RED and GREEN Power ON and OFF switches

FUEL GAUGE: The PSC Baby Zeus is equipped with an easy to read and easy to understand multicolored battery “Fuel Gauge”. Just a quick glance and you will immediately know the charge
condition of your battery. A full row of Green LEDs indicates a fully charged battery. As thebattery is discharged, the LEDs slowly go out. It is similar to reading the fuel gauge in your car.
When the last (left most) RED LED goes out, the unit will shut down to protect the LiFE batteries
from deep discharge. The unit must then be plugged into AC power to re-charge the batteries
and/or power up your equipment. Both charging and use can be done simultaneously.

AC INDICATOR: Whenever the unit is plugged into AC power, the BLUE “AC” LED will lightindicating AC power is connected. Whenever the AC indicator is lit, the batteries will be charged(if needed). In addition, you can power your equipment anytime the unit is connected to AC
power whether or not the battery is fully charged. Please note that the AC indicator may stay on
after the unit is unplugged for several minutes if the unit was in a high charge mode when it was
unplugged. This is normal and nothing to be concerned with.

BATTERY PROTECTION FUNCTION:
battery in four different ways:

The Internal protection circuitry protects the LiFEPO4

1. It protects the battery from deep discharge conditions.
2. It protects the battery from over charge conditions.
3. It protects the battery from overly high discharge rates (short circuits).
4. It protects the battery from excessive charge currents.
If you were to somehow short out multiple outputs of the PSC Baby Zeus, the battery protection
will disconnect the batteries from the load. If this happens, the protection circuit can be resetby plugging in the PSC Baby Zeus to AC power and the protection circuitry will automatically bereset.

REMOTE CONTROL: The remote-control box that is included with your PSC Baby Zeus serves
several functions. It can be used to remotely turn on and off the unit. This will allow you tomount the Baby Zeus main housing in a convenient place on your sound cart. The remote control
also has a battery charge level indicating “Fuel Gauge” that duplicates the meter on the main
unit. Additionally, the remote-control features two (2) USB charging ports for your convenience.
These two USB charging ports output 5Vdc up to a total of 4 Amps of output current. Lastly, theremote control box features a bright BLUE LED indicating AC power is connected to the Baby
Zeus.

SPEAKON CONNECTOR: The Baby Zeus is equipped with one 2 pole SpeakOn connector. Thisconnector is used for the connection of an external battery. Using this connector, you can add a
PSC Pelican LiFE Battery for extra battery capacity. The polarity of this connector is conventional
SpeakOn. The center most contact is Positive (+) and the outer ring connection is Negative (-)

CHARGING: Your new Baby Zeus contains a built-in charger designed to charge the internal
LiFEPO4 battery and also charge most external LiFEPO4 batteries such as the PSC Pelican Life
Battery. This connector allows you to connect an external battery to increase the battery
capacity of the Baby Zeus. The PSC Baby Zeus will operate from a wide range of AC power so you
can plug it in anywhere world without having to worry about making adjustments. The charger
circuit used in the Baby Zeus has been specifically designed for charging the batteries while thebatteries are in use powering low noise audio equipment. Unlike most battery chargers, ours
have a very low noise floor. Typical recharge time ranges from 1 to 2 hours with your equipment
turned off. The charging function is automatic and thus, it does not require your assistance inany way. Simply plug the PSC Baby Zeus into an AC outlet and the charging begins (when needed).
Be aware that the Baby Zeus may get warm during use. Be sure to allow ventilation air gaps
around the top panel and rear panel of the Baby Zeus for proper heat dissipation. When using
an additional external battery such as the PSC Pelican LiFE Battery, be sure to use a heavy-duty
interconnect cable. This cable should be made with 12AWG wire and must use SpeakOn
connectors. Please keep this and all battery cables as short as possible for best performance.
We recommend a maximum external battery cable length of 3’ (1M). Charging time will increase
when using an external battery as the changer has more work to do.
EQUIPMENT POWER CABLES: PSC recommends that you use only two conductor, unshielded
16AWG power cable for power distribution. Shielded cable is not recommended as the shield
may cause short circuits between adjacent pins on the connectors. Please keep all cables as short
as possible as this will minimize DC voltage drop across the cable.
WARNING: It is highly recommended that you have your cables built by qualified personnel
and tested prior to use with your Baby Zeus. All power cables should be clearly labeled on bothends as to what they are to be connected to. For example, label one end “Baby Zeus” and theother end “Lectrosonics XXX”. This will help prevent inadvertently connecting the cables tothe wrong piece of equipment. We cannot stress enough the importance of good quality power
cables and careful connections. Poorly constructed and/or labeled cables can result inequipment damage!
POWER FILTERING: All PSC power products contain PSC Quiet Power Technology tm. Thispower filter technology allows the PSC Baby Zeus to deliver clean, quiet DC power for all of yoursound equipment powering needs. These filters include both audio and RF frequency filters toensure trouble free DC power distribution in the field. Nearly all of today’s audio equipment
contain DC to DC convertors within their power supplies. These convertors can and will causeinter-modulation noise when connected to common DC power sources such as a battery. Hereat PSC we firmly believe that proper DC filtering can and will eliminate most noise issues in thefield. Our competitors do not understand inter-modulation noise and thus do not take theadditional steps to prevent it like we do at PSC. Though not every piece of equipment will suffer

from inter-modulation noise issues. Here at PSC believe that the extra parts cost and design time
are worth it if because we think you deserve the best quality DC power available.

PSC Quiet Power tm Filters partially shown behind output XLRs.

FUSING: Internally, the LiFEPO4 cells are protected against many typical faults via electronicmonitoring and automatic fault protection. In addition, there is a 40 Amp Slow Blow automotive
blade style fuse for ultimate safety. This fuse should never blow in normal use. If you everexperience a blown fuse, something is wrong with your setup. Please call PSC for technicalassistance.
STORAGE: Please note that all rechargeable batteries slowly self discharge while in storage. If
you store this battery, it must be fully recharged prior to storing it. It should also be charged
every two months while in storage. Failure to follow these instructions will cause damage to thebattery and will not be covered under the PSC warranty.
