5.0 MAINTENANCE
Become thoroughly familiar with the equipment, but at no time go beyond the specific proce-
dures in this manual while performing maintenance or correcting a malfunction. If you have any
doubt as to what must be done, call Vertiv 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 maintain historical service records.
• Keep the UPS free of dust and any moisture.
• Keep the UPS cool:
•
Battery systems must be kept in the range of 72-77°F (22-25°C) in order to meet design specifications
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. However, performance and longevity will
be optimized when the UPS is operated at the same temperature as the batteries.
• Keep connections tight.
• Tighten all connections at installation and at least annually thereafter. (See
5.1
Record Log
Set up a maintenance log to record scheduled checks and any abnormal conditions.
The log should have space for all metered data 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.
Vertiv recommends a periodic walk-through inspection of the UPS and battery rooms to check
for visible and audible indications of problems. Log the inspection, metered parameter indications
and any discrepancies.
