Maintaining the IAC
The components inside the Integrated Accessory Cabinet (IAC) are secured to a sturdy
metal frame. All repairable parts and assemblies are located for easy removal with very
little disassembly. This design allows authorized service personnel to perform routine
maintenance and servicing quickly.

Remember that the UPS system is designed to supply power
EVEN WHEN
DISCONNECTED FROM THE UTILITY POWER
. The IAC interior is unsafe until the UPS is
shut down (inverter output and bypass) and bypass utility power to the IAC is
disconnected.

The IAC requires very little preventive maintenance. However, the system should be
inspected periodically to verify that the unit is operating normally.

3.
Verify the operating environment is within the parameters specified in Chapter 7,
“Product Specifications”, and Drawing 164201590-2 on page A-6.
