EPS 7000 Single Module

3.3Preventive 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 EPS 7000 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 thoroughly read this manual, and reference the EPS 7000 Installation Manual for Single Module and Shared systems (MGE part number 86-134003-

00)or the EPS 7000 Shared Systems Users Manual, (MGE part number 86-134005-00), to become familiar with the indicators, controls, and operation of the EPS 7000 systems.

a.Isolate and de-energize all EPS 7000 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 EPS 7000 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 User’s guide.

f.Test the main operating sequences as applicable to your equipment configuration and installation.

3.4Replacement Parts

There are no user replaceable parts inside the EPS 7000.

Three levels of replacement parts are available for the EPS 7000. 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 unaccept- able 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

AThis 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.

BThis level of replacement parts is recommended when the user can tolerate short-duration UPS down-time to obtain replacement parts in the event of a major UPS failure. This level of replace- ment parts consists of consumable items, specifically fuses, air filters, an inverter leg, and the most critical circuit board assemblies.

CThis level of replacement parts is recommended when the user can tolerate only a minimum of down-time in the event of a major UPS failure. This level of replacement parts consists of consum- able items, specifically fuses, air filters, an inverter leg, and a complete set of circuit board assemblies.
