Figure Placement of UPS and other cabinets
2-1
Electrical connections and cabinet interconnections will vary
depending upon the configuration of your Comet UPS
system. Refer to Figure 2-2 and to the installation drawings
supplied with your equipment.
The connections to be made are the three phases, and
ground cables from the utility AC power source to the UPS.
The main AC input cables are terminated at the "Main Input"
Terminal Blocks (TB1). Complete wiring instructions for your
installation are provided on the installation drawings supplied
with the equipment.
The connections to be made are the three phases, and
ground cables from the bypass AC input power source to the
UPS. The bypass AC input cables are terminated at the
"Bypass Input" Terminal Blocks (TB3) if present. This option
provides a separate AC input source for bypass operation.
The control connections are available for "Remote
Emergency Power Off" (REPO) through a customer-supplied
normally closed pushbutton. With REPO connected, the
jumper on the "REPO" terminal blocks must be removed.
