immediately you DO NOT HAVE a magnetic switch. If the dust collector does not start, press the Start or
On button on the dust collector switch. If it starts when you press the On button then you DO HAVE a
magnetic switch.
Contactor Preparation
The iVAC Contactor comes with a control cable, 1 small cable gland and 2 larger cable glands. The small
cable gland is for the control cable. The larger glands are for the power cables that you must supply.
Decide where you will mount the contactor and where each cable will enter the contactor enclosure.
Knock out the filler in the appropriate holes of the contactor enclosure and install the cable glands.
Mount the enclosure in your preferred location using round or pan head screws (and a washer if
necessary) through the holes where the cover securing screws go.
Put the end of the control cable through the small gland and secure it by tightening the gland cover nut.
Connect the spade connectors to terminals A1 and A2 of the contactor. It doesn’t matter which wire
(black or white) goes on which terminal. Connect the green ground wire with the ring terminal to the
ground bar in the bottom of the contactor enclosure.
