Chapter 2 Installing IPS-4240 and IPS-4255
Installing IPS-4240-DC
To install IPS-4240-DC, follow these steps:
Step 1
Position IPS-4240-DC on the network.
Step 2
Attach the grounding lug to the side of the appliance.
Note
Use 8-32 screws to connect a copper standard barrel grounding lug to the holes. The appliance requires
a lug where the distance between the center of each hole is 0.56 inches. The ground lug must be NRTL
listed or recognized. In addition, the copper conductor (wires) must be used and the copper conductor
must comply with the NEC code for ampacity. A lug is not supplied with the appliance.
Step 3
Place the appliance in a rack, if you are rack mounting it.
Step 4
Terminate the DC input wiring on a DC source capable of supplying at least 15 amps.
A 15-amp circuit breaker is required at the 48-VDC facility power source. An easily accessible
disconnect device should be incorporated into the facility wiring.
Step 5
Locate the DC-input terminal box.
Step 6
Power off IPS-4240-DC.
Make sure that power is removed from the DC circuit. To make sure all power is OFF, locate the circuit
breaker on the panel board that services the DC circuit, switch the circuit breaker to the OFF position,
and tape the switch handle of the circuit breaker in the OFF position.
Step 7
Remove the DC power supply plastic shield.
