MGE UPS Systems EPS 6000, Installation Manual

Page: 35 / 72

Electrical room package
The electrical room package option allows configuration of all input and output cables, or
selected cables, through the top of the enclosures. It features separate main AC input
(mains 1) and bypass AC input (mains 2) feeder support. The electrical room package is
standard on all EPS 6000 modules configured for shared systems.
Computer room package
The computer room package option allows configuration of the EPS 6000 UPS using a
single utility AC source for both main AC input (mains 1) and bypass AC input voltage
(mains 2). The computer room option includes additional filtering, making the EPS 6000
UPS fully compliant with the requirements of FCC part 15, subpart J, class A, and the
National Electrical Code (NEC) article 645, Electronic Computer/Data Processing
Equipment.
Additional battery cabinets
Up to a maximum of four battery cabinets can be supplied for a single EPS 6000 UPS
module, making additional back-up time available during power outages.
Input filter
An input harmonic current filter is standard on 500 and 750 kVA units, and is available for
other EPS 6000 UPSs. For some power levels, the input filter is installed within the UPS
enclosure. For others, the input filter is installed in an auxiliary cabinet.
Input or output transformers
The single-module EPS 6000 UPS can be equipped with an isolation or autotransformer
on both the input and output. The transformer provides battery isolation or voltage step-up
or step-down as required for the particular installation.
The shared system EPS 6000 UPS can be equipped with isolation or autotransformers,
but only on the input.
High interrupting capacity circuit breakers
375 kVA EPS 6000 UPS modules are equipped with circuit breakers rated at 30 kAIC.
Standard on 500 kVA and 750 kVA systems, and available as an option on others, are
circuit breakers with a rating of 65 kAIC.
Maintenance bypass
For single module EPS 6000 systems, the maintenance bypass option provides a direct
bypass AC input source (mains 2) that can be used to supply the load while the UPS
module is being serviced.
For shared EPS 6000 UPS modules, maintenance bypass is provided by the SSC,
allowing any or all attached UPS modules to be taken off-line while the SSC supports the
attached load from its bypass source. As an option, the SSC can be equipped with its own
maintenance bypass, allowing the SSC as well as any/all attached UPS modules to be
serviced while the load is supported by the maintenance bypass AC input source.
Output distribution cabinet
Some single-module EPS 6000 systems can be provided with a output distribution cabinet,
with up to four output circuit breakers.
Remote alarm status panel (RASP)
For single-module systems, a remote alarm status panel (RASP) is available. The RASP
