Connecting the power cord for a PSR150-D1 power module
WARNING!
• To use a –48 VDC power source for power supply, use the power cord shipped with the power
module.
• To use an RPS for power supply, purchase a power cord compatible with the RPS yourself.
• To connect a DC power cord to a –48 VDC power source, identify the positive (+) and negative (-)
marks on the two wires of the power cord to avoid connection mistakes.
To connect the power cord for a PSR150-D1 power module:
1.
Wear an ESD wrist strap and make sure it makes good skin contact and is reliably grounded.
2.
Unpack the DC power cord, correctly orient the connector at one end of the cable with the
power receptacle on the power module, and insert the connector into the DC-input power
receptacle (see callout 1 in Figure2-27).
The power receptacle is foolproof. If you cannot insert the connector into the receptacle,
re-orient the connector rather than use excessive force to push it in.
3.
Tighten the screws on the connector with a flat-blade screwdriver to secure the connector in the
DC-input power receptacle (see callout 2 in Figure2-27).
4.
Connect the two wires at the other end of the power cord to a –48 VDC power source or an
RPS.
