Pressure Switch Wiring (For Compressors Not Requiring a Starter)
A – To/from motor (factory connection)
B – To/from power supply (customer connection)
Ground wires not shown for clarity. Equipment must be properly
grounded.
IEC POWER CONNECTION AND OVERLOAD
ADJUSTMENT
IEC Connection
A = Incoming power leads
B = Existing control circuit wires
C = Contactor
D = Thermal overload
E = Stop/test button
F = Incoming grounding lug (see note 2)
G = Motor leads
H = Reset button & selector switch (set for manual reset)
J = Motor current setting (see note 5)
K = Switch position indicator
L = Coil voltage (see note 1)
M = Incoming power connection (see notes 3 & 4)
1. Confirm that the supply voltage matches the voltage rating of the
starter/contactor.
2. Connect the power supply to a properly grounded electrical
circuit with specified voltage and fuse protection.
3. When connecting the incoming power wires to the contactor,
ensure that the existing control circuit wires remain under the
terminal pressure plates and are secure after tightening the screw
terminals.

4. Refer to the torque values listed on side of the contactor when
tightening the wire terminal screws.
5. The overload current setting formula is as follows:
Motor Nameplate Amps X Motor Service Factor = Overload
Setting
Example: 10.0 (Motor Amps) x 1.15 (Service Factor) = 11.50 Overload
Setting
GASOLINE ENGINE COMPRESSORS
If you will be making connections to a remote battery, the
engine on the compressor must be equipped with an alternator.
BATTERY. A 12 volt battery with a minimum current rating of 275
CCA (cold cranking amps) and minimum ampere-hour rating of 24 Ah
should be sufficient for cranking most electric start engines.
BATTERY CABLES. Refer to the following table for size and length
recommendations.
