This HAS to be wrong. The motor current does not go through
the pendant. The wires there only carry signal voltages. The
heaters just have to be in the came cabinet as the motor contactors.
Whether thay are actually a part of the contactor or a separate unit
near one of them is up to the designer, but it would be INSANE
(and probably an electrical code violation) to put them in the
pendant.
