position). Optional distribution circuit breakers should be in the OFF (open) position. Customer-
supplied downstream protective devices and distribution circuits
should be OFF (open).
The lugs used to secure the cables should be torqued as per the recommendation listed in
“Cable preparation for field wiring,” MGE document 9-00038-00.
The connections to be made are the three phase and
ground cables from the utility AC power source to the UPS
module. Complete wiring instructions for your installation
are provided on the installation drawings supplied with the
equipment.
For 480 VAC systems without input isolation, the input power connections will terminate at the
busbars leading to circuit breaker Q1. For input voltages other than 480 VAC or systems with
input isolation, the input power connection will be made to an isolation, step-up or step-down
transformer.
The connections to be made are the three phase, ground,
and optional neutral cables from the bypass AC input
(mains 2) power source to the UPS enclosure.
In a computer room configuration or for voltages other than
480V, where a single AC input source is used to supply
both main AC input (mains 1) and bypass AC input (mains 2) connections, the bypass AC
input is derived from the main AC input by a set of jumpers. These jumpers are installed at the
factory.
The connections to be made are the positive (+), negative
(–), and enclosure ground connections between the battery
cabinet and the UPS module. Additionally, control
connections between the battery temperature sensor and
the UPS module must be installed. Refer to the installation drawings supplied with the UPS,
the battery cabinet, and the battery temperature sensor.
The connections to be made vary depending on your
system configuration. Typically, EPS 6000 systems are
designed to make interconnection easy to complete and
verify; however, always follow the installation drawings
provided with the system.
Most inter-cabinet cables and hardware are provided by MGE; the customer is responsible for
installing these cables. Some cabling must be supplied and installed by the customer. The
installation drawings supplied with the system give complete details.
