Removing the DC Power Supply Cable
To remove a DC power supply cable from an NSM4000 appliance:
1.
(Optional) Attach an electrostatic discharge (ESD) grounding strap to your bare wrist,
and connect the strap to an external ESD point.
2.
Switch off the external circuit breakers, if they are present, for all the cables attached
to the power supply module. Make sure that the voltage across the DC power source
cable leads is 0 V and that there is no chance that the cables might become active
during the removal process.
3.
Remove the clear plastic cover over the terminal studs on the faceplate.
4.
Remove the screws from the terminals, using a Phillips screwdriver, number 2, to
loosen and remove the screws. Save the screws.
5.
Remove the cable lugs from the terminals.
6.
Remove the screw from the grounding terminal using a Phillips screwdriver, number
2, to loosen and remove the screw. Save the screw.
7.
Remove the grounding lug from the terminal.
8.
Carefully remove the power cable from the DC power source.
NOTE: Ensure that the cable is not touching or in the way of any
components, and that it does not drape where people could trip on it.
