Designation	Connection	Supply Wire Gauge (AWG - Cu)		Maximum Tightening Torque
		Minimum	Maximum	(in-lbs)
AC Line Input	L1, L2	22	12	12
Motor	U, V, W	22	12	12

A. AC Line Connection – Wire the AC line input to L1 and L2 terminals of Terminal Block TB1 as shown in Figure 4. Be sure both Jumpers J1 and J2 are set to the “115V” posi- tion for 115 Volt AC line input or to the “230V” position for 208/230 Volt AC line input.

B. Ground Connection – Earth ground the control chassis using the green ground screw that is pro- vided on the inside of the control to the right side of Terminal Block TB1 as shown in Figure 4.

watertight seal is used to cover the hole in the front
cover. Connect the remote main speed poten-
tiometer wires to P1 (low side), P2 (wiper) and P3
(high side) terminals as shown in Figure 5.

E. Remote Start/Stop Switch Connections – The control is supplied with a prewired Start/Stop switch, mounted on the front cover. To operate the control from a remote Start/Stop Switch (type (ON)-OFF-ON, SPDT), remove the white, black and red wires from RUN, COM and STOP terminals. The leads may be taped and left in the control. The switch assembly may be removed if a watertight seal is used to cover the hole in the front cover. Connect the remote Start/Stop Switch wires to RUN (momentary), COM (com- mon) and STOP (constant) terminals as shown in Figure 6. After applying power, momentarily set the Start/Stop Switch

to the "START" position. The motor will operate at the set speed of the Main Speed Potentiometer. To stop the motor, set the Start/Stop Switch to the "STOP" position.
