Series DPB Busway Installation & Operation Manual
ACCUMULATOR PCB
All communications (power data) from the
Tap Off Boxes are transmitted through the
Accumulator Board (Figure 25). 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 26) located inside the BCMS
Monitoring Module 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 provides a 24 VDC source along the bus rail
communications cable to power the intelliBUS (Branch
Monitoring) circuit boards in Tap Off Boxes. It is important
that the Power Inserter be configured for the correct
AC input voltage. See Table 1. 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.
