Maintaining the UPS System

12

12.1 General

The components inside the UPS cabinet are secured to a sturdy metal frame. All repairable parts and assemblies are located for easy removal, and very little disassembly. This design allows authorized service personnel to perform routine maintenance and servicing quickly.

You must schedule periodic performance checks of your UPS system to keep it running properly. Regular routine checks of operation and system parameters will enable your system to function efficiently for many trouble-free years.

12.2 Important Safety Instructions

Remember that your UPS system is designed to supply power EVEN WHEN DISONNECTED FROM THE UTILITY POWER. The UPS cabinet interiors are unsafe until the DC power source is disconnected and all capacitors are discharged. After disconnecting the utility power and the DC power, authorized service personnel should wait at least 5 minutes for capacitor bleed off before attempting internal access to the UPS cabinet.

WARNING:

Servicing and maintenance should be performed only by qualified service personnel.

DANGER:

LETHAL VOLTAGE PRESENT: This unit should not be operated with the cabinet doors open or protective panels removed. Do not make any assumptions about the electrical state of any cabinet in the UPS system.

Since each battery string is an energy source in itself, opening the Battery Circuit Breaker does not de-energize the voltage within the battery string. DO NOT ATTEMPT TO ACCESS ANY INTERNAL AREA OF THE BATTERY STRING YOURSELF. VOLTAGES ARE ALWAYS PRESENT IN THE BATTERY STRING. If you suspect that a battery string needs service, you should contact your local field service office.
