2. Pay attention to the direction of rotations when using three phase motors.
Single phase motor wiring
(See Fig.

)
a. When power supply wires are active wire L and neutral wire N ,connecting active wire
L to terminals of AC contactor marked L1, connecting neutral wire N to terminals of AC
contractor marked L3.
b. When power supply wires are two active wire L ,connecting to terminals of AC
contactor marked L1, L3 respectively.
c. Connecting the limit switch: Remove the short wire connecting terminal 4# of control
button and A2 of AC contactor firstly (See Fig. 42), then connect wire C#(Black wire) of
limit switch with terminal 4# of control button and connecting wire NC#(red wire) with
terminals A2 of AC contactor respectively. (See Fig. 43)
The interior wire of limit switch connecting NC# and C#, refer to Step H.
