shown below. Do not connect to the output terminals of the overload relay. Use the wire size recommended
for your unit.

motor starter to the terminals labeled
“SW”. Use AWG 16 wire for the circuit.
7. If your system does not utilize a heater off-on switch, connect the normally closed auxiliary contact directly to
the terminals labeled
“SW” (TB1). Note: The cover of the motor winding heater depicts the connection
diagram (See wiring diagrams below).
8. If required, connect the normally open contact from the motor overload to the overload connection as shown
