Maintaining the UPS System

The components inside the UPS cabinet are secured to a sturdy metal frame that is supported by the UPS magnetics. This design allows authorized service personnel to remove repairable components with very little disassembly. All repairable parts and assemblies are located in the front of the UPS, allowing all routine maintenance and servicing to be performed with front panel access.

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

Important Safety Instructions

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

WARNING:

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

WARNING:

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.

WARNING:

Battery cabinet maintenance or battery replacement should be performed by authorized service personnel only. Keep unauthorized personnel away from battery cabinets.

Since each battery cabinet is an energy source in itself, opening the Battery Circuit Breaker does not de-energize the voltage within the battery cabinet. DO NOT

ATTEMPT TO ACCESS ANY INTERNAL AREA OF THE BATTERY CABINET YOURSELF. VOLTAGES ARE ALWAYS PRESENT IN THE BATTERY CABINET. If you suspect that a battery cabinet needs service, you should contact your local field service office.

If the cabinet requiring service was not provided by the UPS manufacturer, refer to the battery cabinet manufacturer’s operating manual for instructions on battery cabinet installation and maintenance, or contact your local field service office.
