The control board provides the economizing function
for the main coil circuit. The L63 interlock used in
the economizing circuit on the SJA800A contactor is
therefore not needed in this design. It has been
removed from the SL800 Classic contactor.
WIRING
Refer to Figure 4 for standard control wiring for
magnetically held contactors. To close the contactor,
apply power to terminals 1 and 2 on the control
board. Power must be maintained to terminals 1 and
2 to keep the contactor in the closed position. The
closing coil is connected to terminals 5 and 6.
