Anderson Manufacturing AV-9000 manual Wiring Connections Inputs

2.3 WIRING CONNECTIONS - INPUTS

All wiring connections are typically made to the instrument at the time of installation. Connections should be made at the terminal blocks, one 14 gauge wire maximum, using copper conductors except for thermocouple inputs. See Figure 2-4 (below) for the terminal block locations. The recommended torque for the AC Mains connector on the power supply board is 113oz-ins and the recommended torque for all other connectors in the unit is 85oz-ins.

The instrument case may have numerous conduit openings, EC1 - EC6, depending upon the number of inputs and outputs specified (EC5 and EC6 are not included on all models). To help minimize electrical noise that may adversely affect the operation of the instrument, do not run input and/or 4-20mA output connections through the same conduit entry as relay or power supply connections. See Figure 2-1B (page 2-2) for conduit opening locations.
