Power Stack Frame Installation 3-7
1503E-IN001E-EN-P – June 2013
A T T E N T I O N A T T E N T I O N It is the responsibility of the OEM to ensure that
the final enclosure is suitably bonded to ground,
and that provisions for grounding are made
according to local electrical codes and
standards.
The CLGD power assembly is mounted on the front bottom of the
frame (refer to Figure 3.4). All secondary connections are pre-wired
for the power stack frame. It requires a 110/120 or 220/240 VAC
(50/60 Hz), 50 VA, primary source of power. Refer to Chapter 7 for
typical wiring diagrams.
NOTE: There are three individual cable loops (one for each
phase) connected in series. The cable length must be 6.4
metres (21 feet). Do not cut the extra length from these
cables, as they represent the load for the transformer in
the above power assembly. If they are shortened, the
loop current will be incorrect, and the CLGD boards
may not function properly during stop maneuvers.
