THE CONTROLLER
An A2l0 or A250 motor controller. when wired as shown in the
appropriate connection diagram will operate as a full voltage
starter and will give protection against overload, but not
against short-circuit currents, when wired and provided with
overload relay (OlR) heaters as listed in heater selection tables
or when used with any means of inherent protection activated
by motor temperature.
The controller should be protected against short circuits by
providing branch circuit protection not to exceed the maximum
protective device ratings listed in Table II.

This industrial type control is designed to be installed,
operated, and maintained by adequately trained workmen.
These instructions do not cover all details, variations,
or combinations of the equipment, its storage, delivery,
installation, check out, safe operation, or maintenance. Care
must be exercised to comply with local, state, and national
regulations, as well as safety practices, for this class of
equipment.
AUXILIARY CONTACTS - TYPE J
Two Jll auxiliary contacts, each with one normallyopen pole
and one normally-closed pole are supplied with reversing
controllers. One pole is used as the holding circuit auxiliary.
The other pole serves as an electrical interlock. A maximum
of three auxiliary units can be installed in each reversing
contactor with terminals either in line or in a right angle
relationship to the power poles. Auxiliary contacts mount by
means of a spring clip and retainer screw. To remove the unit
rotate the retainer screw several times (counterclockwise)
and then slide the auxiliary contact unit out of the recess.
