Installation Instructions

CPO-PC400-W/CPO-PC400-UW HVAC CONTROLLER
9 EN0B-0085 IE10 R0420
A max. of 16 Panel Bus I/O modules can be connected to
one Panel Bus. The current consumption of the individual
Panel Bus I/O modules varies according to model. For
more information on Panel Bus I/O modules, see
“Technical Literature” section on page 40.
Connection to BACnet MSTP Bus
The CPO-PC400-W/CPO-PC400-UW can communicate
with other controllers, e.g., CPO Unitary Controllers, CPO-
VAV2A, CP-VAV, CPO-R Series, CP-SPC, and CPO-DIO
through BACnet MSTP Buses.
The current consumption of the individual BACnet Bus
devices varies according to model. For more information on
BACnet Bus devices, see “Technical Literature” section on
page 40.
Connection to Field Buses
The CPO-PC400-W/CPO-PC400-UW can communicate
with ComfortPoint
TM
Open Field Bus Adapters.
There are four ComfortPoint
TM
Open Field Bus Adapters to
choose from (see Table 15 on page 9).
Fig. 2. CPO-FBA Dimensions (mm)
A max. of 31 FBAs can be connected to one Field Bus. Each
CPO-FBA-1A has a current consumption of 213 mA. The
total current consumption of the max. number of FBAs per
Field Bus thus amounts to 31 x 213 mA = 6603 mA.
Fusing: See “Fusing” section on page 11.
For more information on Field Bus Adapters, see “Technical
Literature” section on page 40
Connection to Modbus RTU
The CPO-PC400-W/CPO-PC400-UW can communicate
with power meters, and NXL Inverters through Modbus.
Fusing: See “Fusing” section on page 11.
The current consumption of the individual Modbus devices
varies according to model. For more information on
Modbus devices, see “Technical Literature” section on
page 40.
