To connect 110-120 Volts to the coil, rewire the coil per the wiring diagram label on the side of the contactor.
Next, connect a wire from terminal V of the coil to neutral. See figure C.
The 279-230-5 magnetic starter is shipped with the coil wired to accept 575 Volts, 60 HZ. It can not be
rewired.
The 279-231-5 magnetic starter is shipped with the coil wired to accept 190/240 Volts 50/60 Hz. It may be
rewired to accept 380/460 Volts 50/60 Hz.
d.
There are two remaining blue wires in the submerged pump junction box. These are wired according to the
type of dispenser used.
Installations using mechanical dispensers must be connected for two-wire control. Connect either blue wire
to terminal L3 in the Magnetic Starter. Connect the other blue wire to one side of the “on-off” controls. The
“on-off” controls must be of explosion proof construction. Connect a Black wire from the other side of the
“on-off” control to terminal 3 in the magentic starter. See figure B.
Installations using electronic dispensers must be connected for one-wire control. Connect either blue wire to
terminal 3 in the Magnetic Starter. Connect the other blue wire to the “hot” feed from the dispenser. The
coil in the magnetic starter must be rewired for 115 volt and connected as shown in figure C.
Installations using loading racks only, may be connected for two-wire or three-wire control.
For two-wire control, connect either blue wire to terminal L3 in the magnetic starter. Connect the other
blue wire to one side of the “on-off” controls. The “on-off” controls must be of explosion proof
construction. Connect a Black wire from the other side of the “on-off” control to terminal 3 in the
magentic starter. See figure B.
For three wire control, connect either blue wire to terminal L3 in the Magnetic Starter. Connect the
other blue wire to one side of the “on-off” switch. The “on-off” switch must be of explosion proof
construction. Connect a Black wire from the other side of the “on-off” switch to terminal V in the
magentic starter. Connect a red wire from terminal 2 in the magnetic starter to the “on-off” switch. See
figure D.
3-wire control requires the use of an auxiliary contact in the magnetic starter. This
auxiliary contact is not standard equipment in the starters supplied by Red Jacket,
and must be ordered as an option. Use Furnas auxiliary field kit 49D2125001 or
equivalent.
e.
Install proper overload heaters into magnetic starter.
Three phase pump/motor units must have proper overload and quick trip heaters
installed in the control box.
