70 Check Point UTM-1 Edge User Guide
Connecting a 24V Power Supply
Warning: Always turn off the 24V DC industrial power supply before
wiring, installing, or removing the UTM-1 Edge X Industrial appliance.
Failure to do so may cause faulty operation.
To connect 24V power supply
1. Turn off the 24V DC industrial power supply.
2. Prepare a wire harness composed of three wires.
Each wire must meet the following requirements:
• 22 gauge (AWG) or more
• 105ºC insulation rating or more
The wires should be color coded as follows:
• Black wire for (-)
• Brown wire for (+)
• Green and yellow wire for GND
3. Measure the distance between the UTM-1 appliance and the 24V DC industrial
power supply, and cut the wires to the required length.
Note: If the distance to the power supply is greater than five meters, use wires with a
higher gauge. Refer to your wires' derating and electrical parameters for guidelines.
4. Prepare one end of the harness for connection with the UTM-1 appliance, by
doing the following:
a. Strip the wires about 6-7 mm.
b. If desired, apply a splice cap to each of the three stripped wires.
This step is optional.
c. Using a small flathead screwdriver, loosen the screw in the 24V DC
connector plug that came with the UTM-1 appliance.
d. Hold the plug groove-side up, with the terminals facing you.
e. Insert the Green and Yellow (GND) wire in the center terminal.
