Install the contactor on the DIN rail as shown in fig. 1. Vertical mounting operation is recommended. Wire the contactor to the input control side following the corresponding wiring diagram (fig. 3 or fig. 4). AWG #24 minimum, AWG #12 maximum (0.2-3.3 mm2), choose wire gauge according to load current. Maximum recommended terminal screw torque input To remove from DIN rail 4.3 in-lbs (0.5 Nm). Wire the contactor to the AC Line side (L1, L2 & L3) and to the Load side (T1, T2 & T3). AWG #24 minimum, AWG #10 maximum (0.3-5.3 mm2), choose wire gauge according to load current. Maximum To install on DIN rail recommended terminal screw torque output 12 in-lbs (1.37 Nm). If multiple units are installed be sure to follow derating curve (fig. 2). fig. 1 Mounting/Dismounting contactor on DIN rail.
