Control Circuit Wiring
Mount the control circuit remotely by following the procedure below.
Warning:
Ensure that all power is OFF before wiring any circuit.
Wiring
The input/output connector for the control circuit is a 48 pin type F Eurocard connector, (DIN 41612). Shielded
cable must be used when running the cables to the sensing elements, as well as the signal voltage outputs if they are
used. Refer to Table 2-1 for the pin designations.

Remote Mounting
1. Mount the control circuit rack to an appropriate and accessible surface. (See Figure 2-1.)
2. FCI's recommendation is to install conduit between the local enclosure and the remote enclosure, as well as
installing conduit between the remote enclosure and the power source and monitoring circuit. Provide water
tight hardware and apply thread sealant to all connections to prevent water damage.
