a. Isolate and de-energize all EPS 6000 UPS equipment for all
maintenance operations.
b. Ensure that all equipment is clean and free of loose dust, dirt, and debris. The
exterior of all enclosures may be cleaned with a mild solution of soap and water,
lightly applied with a lint-free cloth.
c. Inspect the air intake and exhaust plates and clean as required. Verify that air
flows freely through the equipment. Clean the air intake and exhaust plates, and
the enclosure interior, with a vacuum cleaner.
d. The EPS 6000 UPS module is equipped with air filters that should be changed at
regular intervals. Inspect the filters regularly to determine how long the filters will
last in your installation.
e. Initiate the start-up procedure, as described in Section 2.4.1.
f. Test the main operating sequences as applicable to your equipment
configuration and installation.
There are no user replaceable parts inside the EPS 6000
UPS.
Three levels of replacement parts are available for the EPS 6000 UPS. The three levels are
designated A, B, and C. The level that you should keep on hand for your installation will vary
depending on the type of maintenance planned on site, and the configuration of your UPS
system. Having the replacement parts on hand will prevent any unacceptable delays (due to
time involved obtaining spare parts) during critical periods, such as system start-up. Any items
used during start-up will be replaced by MGE at no charge. Contact MGE Customer Support
Services for specific recommendations. A description of each level is provided below:
Level Description
A This level of replacement parts consists of consumable items, specifically fuses and air
filters. It is recommended to have these items on hand during installation of the UPS
systems, including initial start-up.
B This level of replacement parts is recommended when the user can tolerate short-dura-
tion UPS down-time to obtain replacement parts in the event of a major UPS failure. This
level of replacement parts consists of consumable items, specifically fuses, air filters, an
inverter leg, and the most critical circuit board assemblies.
C This level of replacement parts is recommended when the user can tolerate only a mini-
mum of down-time in the event of a major UPS failure. This level of replacement parts
consists of consumable items, specifically fuses, air filters, an inverter leg, and a com-
plete set of circuit board assemblies.
