Series DPB Busway Installation & Operation Manual
ACCUMULATOR PCB
All communications (power data) from the
Tap Off Boxes and End Feed Input PM PCB
are transmitted through the Accumulator
Board (Figure 36). 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
37) 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 provides a 24 VDC source along the bus rail
communications receptacles 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 3. 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.
