3.3 Monitoring System Checklist
Basic Indicators
___ 1. Turn On the building power to the unit, then turn the main input breaker On.
___ 2. Check that the Power LED on the front panel is illuminated.
Manual Restart Check
If the Liebert
®
FPC
™
is equipped with Manual Restart:
___ 1. Turn on building power to the Liebert FPC. Turn Main Input Breaker On.
___ 2. Turn off all building power to the Liebert FPC.
___ 3. Observe that Main Input Breaker automatically trips open upon power loss.
___ 4. Restore building power to the Liebert FPC and return Main Input Breaker to On.
Power Monitor Panel
If the Liebert FPC is equipped with a Power Monitor Panel:
___ 1. Turn On the Liebert FPC.
___ 2. Ensure that the voltage values indicated by the Monitor Panel correspond to the voltage
values measured at the input and output circuit breaker (Steps 10 and 13 in 3.2 - Startup).
Centralized Monitor
If the Liebert FPC is connected to a Centralized Monitoring System:
___ 1. Turn On the Liebert FPC and the Centralized Monitoring System.
___ 2. Verify proper communication to the monitor system operation.
Control Voltage
___ 1. Obtain access to the low-voltage terminals in the low-voltage junction box (if used), or the
adapter board inside unit.
___ 2. With the Liebert FPC On, measure and record the DC control voltage on terminals 1 (+) and 3
(com).
___ 3. Control Voltage = ____________________ (Voltage should be between 16 and 23VDC).
Customer Alarms
If customer alarms are provided:
___ 1. With the Liebert FPC On, simulate alarm operation by jumpering the appropriate low-voltage
control terminals. (Refer to the control wiring installation drawing furnished with the unit.)
___ 2. Verify correct alarm annunciation by the Power Monitor Panel and/or by the Centralized
Monitoring System.
