Cabinets powered by the same service panel
In two-cabinet systems, a #6 AWG ground wire is connected from one
cabinet to the other. The main cabinet is in turn connected to a ground source
(the isolated ground bus in the AC service panel).
Cabinets powered by different service panels
If both cabinets in a two-cabinet installation cannot be powered from the
same service panel, each one must be grounded separately back to the service
panel that supplies it.
Grounding instructions for cabinets
The following procedure describes how to ground the Option 11C Compact
system cabinets. Repeat the steps for each cabinet installed in the system.
Procedure 3
Grounding cabinets
1
If the cabinet is equipped with a power supply unit, make sure
that the AC power cord is disconnected from the power outlet.
2
In multi-cabinet systems, install a #6 AWG ground wire from one
of the ground lugs in the main cabinet to one of the ground lugs
in the expansion cabinet.
Connect the ground wire to the ground lug located in the bottom of the
cabinet (Refer to
).
Route the ground wire through the opening at the bottom rear of the
cabinet.
WARNING
Power should never be connected to a cabinet that is not properly
grounded.
