Step 1 Remove power from the DC circuit.

Warning

Before performing any of the following procedures, ensure that power is removed from the DC circuit. To ensure

 

that 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. To see

 

translations of the warnings that appear in this publication, refer to the Regulatory Compliance and Safety

 

Information document that accompanied this device.

 

 

Step 2 Note the orientation of the DC power supply. The power supply cord should have three wires: 48 VDC Return, -48 VDC, and a safety ground (green wire).

Warning

The illustration shows the DC power supply terminal block. Wire the DC power supply using the appropriate wire

 

terminations at the wiring end, as illustrated. The proper wiring sequence is ground to ground, return to return,

 

and negative to negative. Note that the ground wire should always be connected first and disconnected last. To
