4.4 Remedial Maintenance (continued)

4.4.1 General (continued)

Because of the modular design of the

BalancedPower

Plus

UPS, corrective

action in many instances requires replacement of a major assembly or
subassembly. For this reason, troubleshooting information as contained herein is
generally limited to immediate action that may be taken on site to correct a specific
alarm condition. If such immediate action does not remedy the situation, contact
the 1PM 24-Hour Hotline for assistance.

In general the BalancedPower Plus UPS is designed so that the operator

should not find it necessary to have access to any area of the equipment except the
Digital Monitor Panel and the circuit breakers, switch and fuses inside the right-
hand door.

WARNING

Do not remove front plastic shield,
front panel around the circuit breakers
or either side panel unless
all power to the UPS is OFF. Only
trained maintenance personnel should
remove any of these panels.

4.4.2 Status/Alarm Indicators

The LED status/alarm indicators on the monitor panel are described in

Paragraph 3.4.1. Specific action that may be taken in case of alarm conditions is
described in Table 3-2, a part of Paragraph 3.6.2.
