4.0 Operating Instructions
4.1 Start-Up Procedures
Before 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 start-up procedures.
After initial system start-up, 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, which may require changes to the standard equipment
operation.
4.1.1 Emergency Shutdown
To perform an immediate system shutdown during emergency conditions, open the front
door, and turn OFF the upper left Breaker marked “Main Breaker, Circuits 1, 3, & 5”.
4.1.2 Normal System Shutdown
To perform a normal system shutdown, perform an orderly load equipment (computer
system) 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
PDU’s output distribution (circuit breaker) panels located behind the unit’s front door. Turn
OFF all unit output breakers, and then turn OFF the unit’s main input circuit breaker. To
remove all power from the unit, turn OFF the building power to the unit’s input breaker.
4.1.3 Normal System Start-UP
Check that all circuit breakers are in the OFF position. All unit circuit breakers are
located behind the front doors. Turn ON building power to the unit. Turn ON the unit’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 unit has a voltage meter panel, verify proper output voltages before turning ON output
circuit breakers. Turn ON each output circuit breaker following the load equipment
manufacturer’s start-up sequence.
4.2 Units Without Monitoring
On all units without monitoring, verification of all voltages by a hand held meter is required
before powering any of the load equipment.
4.3 Power Monitor Panel
Monitored Parameters – Is an LCD display is provided to indicate the input./output voltages
(line-to-line and line-to-neutral), output currents (each phase), output kVA, kW, kW-Hours,
power factor, and output frequency. All monitored parameters are sequentially displayed
automatically.
