3.2 KSS-J Models with Decision-Makerr
MPAC 750 Controllers
1. Verify that power has been disconnected as
described in Section 2, Installation Procedure.
2. Use harness leads GM91325, supplied, to connect
the exercise kit according to the wiring diagram in
Figure 10. Connect the timer to the controller
(leads 103 and 104) and connect the fuse block to
the contactor (leads LA and LC). Use piggyback
terminals 233704 at the contactor if needed.
3. Connect the transformer to supply the correct
voltage to the timer. Configure the primary and
secondary transformer connections for the
corresponding system voltage. See Figure 9 and
Figure 11.
