5. CONNECTIONS
5.1 Electrical Connections
All electrical connections are made to the screw terminals at the rear of the controller. They
accept wire sizes from 0.5 to 1.5 mm2 (16 to 22 AWG). The terminals should be tightened to a torque
of 0.4 Nm (3.5 lb in).
.
5.2 Routing of Wires
To minimize the pick-up of electrical noise, the low voltage DC connections and the sensor
input wiring should be routed away from high-current power conductors. If this is impractical, use
shielded cables. In general, keep cable lengths to a minimum.
