1.1
Installation Features
The ITC is designed to be installed in a line-up-and-match or standalone configuration. In a line-up-and-match
configuration power wiring may be routed either external to the cabinet using conduit or the power terminal
wiring channel assembly may be utilized to pass wiring between adjacent cabinets. In standalone
configurations power wiring is routed using external conduit.
To reduce installation time, wiring enters the ITC from the back and is routed to the front panel for easy
connection to the mechanical lugs located on the input and output circuit breakers.
A line-up-and-match ITC is installed adjacent to the UPS or other accessory cabinet. The recommended
installation location is to the left of the UPS cabinet. See Figure 1-2 and Figure 1-3 for line-up-and-match
configuration views.
