Place the power cable that will bring power from the source to the dust collector through the chosen
gland and secure it by tightening the gland cover nut. Connect the green ground wire in this cable to the
ground bar in the bottom of the contactor enclosure.
Connect the black wire in the cable to one of the L1, L2 or L3 terminals of the contactor. It doesn’t
matter which one you choose. Connect the white wire in the cable to one of the remaining L terminals.
Again it doesn’t matter which one. The third terminal will be a spare if your dust collector is a single
phase machine. You will need the third terminal only if your dust collector is a 3 phase machine.
Place the cable that will take power from the contactor to the dust collector through the other large
cable gland and secure it by tightening the gland cover nut. Connect the green ground wire to the
ground bar in the bottom of the contactor enclosure. Connect the black wire in this cable to the T
terminal that matches the L terminal with the black wire. (For instance, if you connected the black wire
of the source cable to terminal L1, connect the black wire of the dust collector cable to terminal T1.)
Connect the white wire of this cable to the T terminal that matches the L terminal with the white wire.
Put the cover back on the iVAC Contactor.
