Field wiring
For all I/O terminals listed in Table 5, use the appropriate gauge wiring. For each spade terminal in this application,
follow the guidelines in Table 5 and use a spade connector with screw terminals.

Note:
Use WECO® 130 Series or WIELAND® Electric 8105B. A maximum rated torque of 4.5 lb·in is acceptable
when you use the WECO 130 Series terminal blocks.
Stacked FC/SA bus terminal block
A dual-stacked connector serves as the FC bus and SA bus port on the PEAK OEM 32 controllers. The upper row
on the connector is the FC bus port. The lower connector row is the SA bus port.

The FC bus connection is software switchable for BACnet MS/TP, Modbus subordinate mode, and N2
communication. Figure 5 shows the BACnet MS/TP connection, and Figure 9 shows the Modbus connection for
the three terminals. The Shield (Shld) is not required for Modbus.
When the FC bus is configured for Modbus protocol, the PEAK OEM 32 controller connects to the network as a
subordinate device. The Modbus register table is not standard but strictly depends on the application loaded on the
controller. The Modbus table is generated during the application development phase.
The PEAK support team identifies the configuration and application for Modbus. The controllers are programmed
based on OEM applications.
