Figure 51 Connect the PSR300-12D1/PSR300-12D2 to a –48 VDC power source
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 51 ). 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 51 ).
3. Connect the other end of the power cord to the –54 VDC RPS.
Connecting the LSVM1AC650/LSVM1AC300
1. Insert the female connector of the AC power cord into the power receptacle on the power module.
2. Use a cable tie to secure the power cord to the handle of the power module (see Figure 52 ).
3. Connect the other end of the power cord to an AC power outlet.
