4.3Routine Maintenance

You are encouraged to become thoroughly familiar with the equipment, but at no time should you go beyond the specific procedures in this manual while performing maintenance or correcting a malfunc- tion. If you have any doubt as to what must be done, call Liebert Global Services at 1-800-LIEBERT for further instructions.

The UPS is designed for unattended operation, but does require some common sense maintenance.

• Keep good records.

Troubleshooting is easier if you have historical background.

• Keep it clean.

Maintain the UPS free of dust and any moisture.

• Keep it cool.

Battery systems must be kept in the range of 72-77°F (22-26°C) in order to meet design specifica- tions for capacity and longevity.

The UPS will reliably meet all performance specifications at temperatures up to 104°F (40°C) and can be slightly derated for operation at even higher temperatures or higher altitudes. However, performance and longevity will be optimized when the UPS is operated at the same temperature as the batteries. Contact your local Liebert sales representative or call 1-800-LIEBERT for fur- ther details.

• Keep connections tight.

Tighten all connections at installation and at least annually thereafter. (See torque requirements, Table 15.)

• Periodically inspect external upstream and downstream circuit breakers to assure that the trip current settings are correct.

• Periodically inspect surroundings and ancillary equipment.

Become familiar with typical ambient conditions surrounding equipment so that abnormal condi- tions may be more quickly recognized. Know what typical meter readings are and where adjust- able settings should be.

4.3.1 Record Log

Set up a maintenance log to record scheduled checks and any abnormal conditions.

The log should have space for all metered parameter indications including phase readings, alarm messages, UPS mode of operation, air filter replacement date and observation notes. A second log should be maintained for the battery module as directed by the battery manufacturer.

A periodic walk-through inspection of the UPS and battery rooms is advised to check for visible and audible indications of problems. Log the inspection, metered parameter indications and any discrep- ancies.

4.3.2 Air Filters

The air filters must be inspected and serviced on a regular schedule. The period between inspections will depend upon environmental conditions. Under normal conditions, the air filters will require cleaning or replacement approximately every two months.

All Liebert Series 610 models have replaceable filter elements built into the full-width grille across the front of the unit. This element can be changed from the front, with the UPS operating.

Liebert Series 610 models rated 300kVA and higher also have recyclable filters built into the front of their base assemblies. These metal filter elements can be removed, washed in water, dried and returned to service.

! CAUTION

Be certain recyclable filter elements are dry before reinstalling them in the UPS.

Abnormal or dusty conditions will require more-frequent cleaning and replacement of air filters. Inspect installations in new buildings more often, then extend the inspection period as experience dic- tates.
