GS160 Assembly 2-23
The dual-AC switch ensures an uninterrupted power supply to the system by
transferring AC power input from the primary source to the secondary source
when the primary stops supplying power. The GS160 system requires one power
dual-AC switch located in the lower cavity of the dual-AC switch cabinet.
The dual-AC switch cabinet is attached to the right of the power cabinet. To add
a dual-AC switch cabinet, proceed as follows: Roll the dual-AC switch cabinet
flush along the side of the power cabinet leaving a minimum gap between
cabinets
.
1. Align cabinet height by adjusting the leveling feet of the dual-AC switch
cabinet
.
2. Once the dual-AC switch cabinet is aligned with the power cabinet, use the
four screws and the Allen wrench supplied with the dual-AC switch cabinet
to secure the cabinets together at all corners
.
3. Connect the system ground wire from the dual-AC switch cabinet to the
power cabinet
.
4. Connect the power cable connector of the AC input box to the power
output connector of the dual-AC switch.
5. Connect the primary power input cable of the dual-AC switch to the primary
power source and the secondary power input cable to the secondary power
source
. Note that the primary power source and the secondary power
source are interchangeable. See the dual-AC switch documentation for
interchanging the power sources.
