Drawing: Frame size S10 (S12) - S10 (S12) - S10 (S12) Step Procedure
1/2
Mount the wye-delta com-
bination to the mounting
plate. (1/2).
3/4
Screw the bottom wiring
kit busbar connections
(3/3.1/3.2/3.3) and the
wye jumper on top to the
busbar connections (4).
1/2/3
Push in the “push-in lugs” for
panel mounting the timing
relay and then screw mount
the timing relay to the mount-
ing plate.
4/5
Break off the extension
pieces on the covers for
the wiring module
.
6/7
Slide on the covers for the
wiring module and the con-
nection covers.
