4.4.1
General
When properly installed, operated and maintained your International Power Machines
BalancedPower II–S (BPII–S) UPS will provide long, reliable power protection with little
need of remedial or corrective maintenance actions. However, this section contains
information as to problem isolation techniques and recommended actions to be taken so as to
effect repairs on the UPS.
Because of the modular design of the BalancedPower II–S (BPII–S) 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 IPM 24–Hour Hotline for assistance.
In general the BalancedPower II–S (BPII–S) 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, switches and fuses inside the front doors.
WARNING
Do not remove the top panel, 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 Indicator
The LED status/alarm indicator on the monitor panel is 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.
4.5 Fuses
There are two (2) fuses below the UPS CONTROL switch inside the front door. If
one of these fuses is blown, the control logic may not become energized at startup. Once the
UPS is started, it will operate even though one or more of the fuses is blown. These are the
only fuses available to the user unless he or she has had authorized factory training.
In case a fuse blows, replace it with a fuse of the same make and size.
