Series DPB Busway Installation & Operation Manual
ACCUMULATOR PCB
All communications (power data) from the End
Feed Input PM PCB are transmitted through
the Accumulator Board (Figure 31). The board
is equipped with a RS-485 serial Modbus
communications serial interface capable of
two-wire or four-wire communications. Refer to
Section "Communications" for details on how to
interface with the serial port for connection to
Building Management Systems (BMS),
Data Center Infrastructure Solutions (DCIM) or
Local Displays.
POWER INSERTER PCB
DC power for all related circuit boards of the Bus Monitoring
System is supplied through the Power Inserter Board (Figure
32) located inside the Bus Monitor Housing on the End Feed
Box. The Power Inserter Board acquires AC power via a
readily accessible disconnect device directly from the End
Feed main AC input bus. It is important that the Power
Inserter be configured for the correct AC input voltage. See
Table 2. For the correct jumper configuration for jumper J2
and J5 located on the Power Inserter Board.
The input power inserter is always fused with Type KTK-R fuses rated at 0.5A.
