4.0 OPERATING INSTRUCTIONS
4.1 Startup Procedures
Before the unit is placed into service after initial installation, after equipment relocation, or after
equipment has been de-energized for an extended period of time, perform equipment inspection and
startup procedures as detailed in 2.0 - Equipment Inspection and Startup and 3.0 - Inspection
and Startup Checklist.
After initial system startup, the following guidelines can be used for standard equipment operation.
These guidelines should be reviewed for any special equipment modifications, special site
considerations or company policies that may require changes to the standard equipment operation.
4.1.1 Emergency Shutdown—If Emergency Power Off switch is supplied
To perform an immediate system shutdown during emergency conditions, rotate the clear protective
cover and push the Emergency Power Off (EPO) switch on the Liebert
®
FPC
™
’s monitoring panel.
If the site is equipped with a Remote Emergency Power Off (REPO) switch to perform an immediate
room shutdown, actuate one of the REPO switches.
4.1.2 Normal System Shutdown
To perform a normal system shutdown, perform an orderly load equipment shutdown according to the
load equipment manufacturer’s recommended shutdown sequence. The load equipment can be turned
Off at each piece of load equipment or at the Liebert FPC’s output distribution (circuit breaker)
panels located behind the Liebert FPC’s front door. Turn Off all unit output breakers, then turn Off
the unit’s main input circuit breaker. To remove all power from the Liebert FPC, turn Off the building
power to the Liebert FPC’s input breaker or junction box.
4.1.3 Normal System Turn On
Make certain all of the Liebert FPC’s circuit breakers are in the Off position. All unit circuit breakers
are located behind the front doors. Turn On building power to the Liebert FPC. Turn On the Liebert
FPC’s main input circuit breaker. If the circuit breaker has been tripped Off (instead of being turned
Off), the circuit breaker handle must be moved to the Off position before being turned On. If the
Liebert FPC has a voltage monitoring panel, verify proper output voltages before turning On output
circuit breakers. Turn On the panelboard main breakers. Turn On each output circuit breaker
following the load equipment manufacturer’s startup sequence.
4.1.4 Manual Restart
The Manual Restart feature is designed to cause the unit’s main input circuit breaker to trip upon
power failure, preventing repetitive application of unstable voltage and allowing for an orderly
system restart. If the main input circuit breaker is tripped upon a power failure, wait until power is
restored, then follow the instructions in 4.1.3 - Normal System Turn On.
4.1.5 Auto Restart
If the Auto Restart feature is selected the unit’s main input breaker will not trip upon power failure,
Auto Restart does not affect the Emergency Power Off circuit—both local and remote EPO switches
will trip the main input breaker when pressed.
Auto Restart can be field-selected by sliding the S1 switch on the adapter board to the Auto position.
The adapter board is located on top of the monitoring enclosure. See Figure 15) for details.
NOTE
Depending on the particular control circuit wiring, operation of the unit EPO switch may cause
other equipment to also shutdown.
