Figure 68 Connect a DC power cord to the PSR300-12D1/PSR300-12D2
Connecting the PSR300-12D1/PSR300-12D2 to a –54 VDC
output RPS
1. Unpack the RPS power cord, identify the plug for connecting to the power module, orient the plug
with the power receptacle on the power module, and insert the plug into the receptacle (see callout
1 in Figure 68 ). The receptacle is foolproof. If you cannot insert the plug into the receptacle,
re-orient the plug rather than use excessive force to push it in.
2. Tighten the screws on the plug with a flat-blade screwdriver to secure the plug in the power
receptacle (see callout 2 in
Figure 68 ).
3. Connect the other end of the power cord to the RPS.
Connecting the PSR750-A
1. Check that the AC power module is off.
2. Pull the bail latch upwards (see Figure 69 ).
3. Connect one end of the AC power cord supplied with the power module to the power receptacle
on the power module (see callout 1 in Figure 70 ).
4. Pull the bail latch down to secure the plug in the power receptacle (see callout 2 in Figure 70 ).
5. Connect the other end of the AC power cord to an AC power outlet.
