3. Installing the CPX-1000
To connect plant battery power and ground to the CPX, follow
these steps:
Step 1
Terminate a #6 AWG frame ground wire in an LCC or LCD
compression lug (with two #10 screw holes).
Step 2
Using two 10-32
×
¼-inch machine screws, attach a frame grounding
cable to the two rear panel ground points. Attach the other end of
this grounding cable to rack ground.
Electro-Static Caution
Use a wrist grounding strap, attached to the grounding jack
on the CPX enclosure, when working with the system. ESD
can seriously damage the printed circuit card assemblies
and solid-state components inside the CPX.
Note
Do not apply power to the CPX until you finish all
installation tasks. Ensure that the shelf circuit breaker is
set to OFF/0.
