5.0 Scope
Maintenance procedures include preventive maintenance, isolation procedures for maintenance, startup for single
and parallel units after isolation, functional and visual checks, software options and configurations, and testing
scenarios.
5.1 Preventive Maintenance
The following preventive maintenance routines should be considered the minimum requirements; your installation
and site may require additional preventive maintenance to assure optimal performance from your installed Galaxy
PW™ and associated equipment. These routines should be performed twice a year (more often if required). We
strongly recommend contracting MGE Customer Support Services for preventive and remedial maintenance.
The technician or electrician performing preventive maintenance on the UPS must read thoroughly this manual
Galaxy PW™ Installation and Users Manual (MGE PN 86-133060-00) and be familiar with the indicators, controls,
and operation of the UPS prior to maintenance.
Technician or Engineer checks for preventive maintenance:
a. Isolate and de-energize all Galaxy PW™ equipment for all maintenance operations.
b. Ensure that all equipment is clean and free of loose dust, dirt, and debris. The exterior of the 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 Galaxy PW™ 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 the Installation and Users Manual section 2.7 System Start-up,
page 2—10.
f. Test the main operating sequences as applicable to your equipment configuration and installation.
