2.1 Site Selection

CautionUse within the following temperature and humidity ranges.
Temperature: -20 to 80 (-4 to 176 ), Humidity: 85%RH or less (No icing, non-condensing)If the SA-500 is installed within the control panel, the ambient temperature of the SA-500 - not theambient temperature of the control panel - must be kept to under 80 . Otherwise the life of electronicparts of this unit will be shortened.
Ensure the mounting location corresponds to the following conditions:• A minimum of dust, and an absence of corrosive gases• No flammable, explosive gases• Few mechanical vibrations or shocks• No exposure to direct sunlight, an ambient temperature of -20 to 80 (-4 to 176 ) that does notchange rapidly, and no icing• An ambient non-condensing humidity less than 85%RH• No large capacity electromagnetic switches or cables through which large current is flowing• No water, oil or chemicals or where the vapors of these substances can come into direct contact with the unit

2.3 Mounting to the Heat Sink
To mount the SA-500 to the heat sink (AQP813, AQP815: Sold separately), use the specified screws.

(Fig. 2.3-1)

3. WiringWarning• Turn the power supply to the unit OFF before wiring. Working on or touching the terminal with the powerswitched ON may result in severe injury or death due to electric shock.
• Do not touch this unit and heat sink during power-on or immediately after power-off.
Burns may be caused as the unit and heat sink will be very hot.
• Do not touch output terminals during power-on or immediately after power-off. Electric shock may result.
• Do not block air circulation around the unit and heat sink. Interference may result in a short circuit fault
or burnout of output terminals due to abnormal heat generation from the unit.
• Be sure to wire the unit securely and use wires with sufficient thickness.
• For the input wiring, use wire with 0.5 mm2 to 1.25 mm2 of thickness, and avoid wiring in parallel with outputcircuit.
• To protect the circuit, it is recommended to install a circuit breaker or a fuse to the load supply voltage
