Series DPB Busway Installation & Operation Manual
INPUT PM PCB
Input Power Monitor (PM) Board: (Figure 38):
this board monitors two separate 3- phase
power sources including voltage, phase
current and neutral, and ground current as
well as four contact alarm inputs.
SAFETY WARNING
CAUTION
ALL VOLTAGE CONNECTIONS MUST BE FUSED!
TAP OFF BOX MONITORING COMPONENTS
Each Tap Off Box is BCMS-equipped (Figure 39)
and interconnected with the Accumulator Board
via the Communications Cable Connection
scheme (Figure 40).
Branch Monitor Sensor Board (intelliBUS): This
board monitors 3- phase current (phases A, B,
C) for each branch circuit. Depending on the
configuration of the system, not all current
sensors may be employed.
Fusing: The Branch Circuit Monitoring system uses
three fuses (one per phase) to protect the voltage
sensing circuits. Fuses are located on the side of
the Tap Off Box (Figure 34) in screw-type safety
fuses holders. Fuses are Type KTK-R rated at 0.5A.
Note that the state of a fuse on the sensing circuit
will not affect the electrical performance of the
Series DPB Bus System.
