Precautions for Use
Installation Precautions

CautionThis instrument is intended to be used under the following environmental conditions(EN61010-1):• Pollution degree 2
Ensure the mounting location corresponds to the following conditions:• A minimum of dust, and an absence of corrosive gases• No flammable, explosive gases• No mechanical vibrations or shocks• No exposure to direct sunlight, an ambient temperature of -10 to 50°C(14°F to
122°F) that does not change rapidly, and no icing• An ambient non-condensing humidity of 35 to 85 %RH• No large capacity electromagnetic switches or cables through which large current
is flowing• No water, oil or chemicals or the vapors of these substances can come into directcontact with the unit.
• When installing this unit within a control panel, please note that ambient
temperature of this unit – not the ambient temperature of the control panel – must
not exceed 50°C (122°F).

Control module QTC1-40(no power supply /communication option)

Caution• The QMC1-MT IP address setting is required for Ethernet communication.
Selection of QTC1-20 or QTC1-40 module address is required to communicate
with QMC1-MT.
• If the QMC1-MT IP address setting has been changed, turn the power OFF andON.
The QMC1-MT IP address setting becomes effective by turning the power OFF
and ON.

The 3rd (a) and 4th (b) bytes of the QMC1-MT IP address (e.g.
192.168.a.b) are set using the QMC1-MT IP address setting rotary switch
or console software.
The factory default for the QMC1-MT IP address is 192.168.0.0.

CautionWhen using the QMC1-MT IP address setting rotary switch
Use a small flat-blade screwdriver to set the QMC1-MT IP address.

• Do not touch live terminals. This may cause electrical shock or problems inoperation.
• Turn the power supply to the instrument OFF when retightening the terminal orcleaning.
Working on or touching the terminal with the power switched ON may result insevere injury or death due to electrical shock.
• Use a soft, dry cloth when cleaning the instrument.
(Alcohol based substances may tarnish or deface the unit.)• As the display section is vulnerable, be careful not to put pressure on, scratch or
strike it with a hard object.

2. Overview

Connection example of QMC1-MT and QTC1-40• Do not connect QTC1-2P (with power supply / communication option) (hereinafterreferred to as QTC1-2P) or QTC1-4P (with power supply / communication option)(hereinafter referred to as QTC1-4P) in the same unit.
• When wiring, do not drop wire scraps into the ventilation window of this
instrument.
It may cause fire or malfunction.
• When wiring, use a crimping pliers and a solderless terminal with an insulation
sleeve in which an M3 screw fits.
• Tighten the terminal screw using the specified torque.
If excessive force is applied to the screw when tightening, the screw or case may
be damaged.
• Do not pull or bend the lead wire with the terminal as the base point during or
after wiring work.
It may cause malfunction.
• This instrument does not have a built-in power switch, circuit breaker and fuse.
It is necessary to install an appropriate power switch, circuit breaker, and fusenear this instrument.
• When wiring the power supply (24 VDC), do not confuse the polarities.
• Use copper wires AWG16 to 14 (1.31 to 2.08 mm2) for the FG terminal and Powersupply terminal.

This instrument fits the following DIN rails.
Top hat rail TH35 JIS C 2812-1988• If this instrument is mounted in a position susceptible to vibration or shock, mountcommercially available end plate at both ends of the instrument.
• When installing, make sure that the orientation (upper and lower) of this
instrument is correct.
• When mounting or removing this instrument on the DIN rail, it must be tilted
slightly.
Secure a space of 50 mm or more in the vertical direction of the instrument,
considering the wiring space of the power supply/communication line and heatdissipation.

Turn off the power supply to this instrument before wiring.
If you work while the power is supplied, you may get an electric shock, which could
result in an accident resulting in death or serious injury.

CautionCaution• Do not use the wrong polarity for the power supply voltage (24 V DC).
• Use copper wires AWG16 to 14 (1.31 to 2.08 mm2) for the FG terminal andPower supply terminal.
