CAUTION
Disconnect power supply before beginning
installation to prevent electrical shock or equipment
damage.
Location
Locate the contactor on a flat, solid surface as close as
possible to the equipment being controlled.
Mounting and Wiring
Disconnect power supply before beginning installation to
prevent electrical shock or equipment damage. Be sure all
wiring complies with local codes and ordinances.
IMPORTANT
Do not exceed the contact and coil ratings when
wiring the contactor into the system.
New Installation
쐃 Mount the contactor in a vertical position for best
performance. Horizontally-mounted contactors have
a 12 percent lower efficiency.
쐇 Use two screws to mount the contactor. Select
models use a shear formed panel tab to mount the
contactor. See Fig. 1.
쐋 See equipment manufacturer wiring instructions or
Fig. 2.
쐏 Attach the line wires to the contactor using terminal
clamp screws.
쐄 Attach the load wires using No. 10 binding screws.
쐂 Use pressure lugs for field wiring with wire larger
than No. 8.

Replacement Installation
쐃 Remove and identify contact and coil leads to
assure correct connection to the new contactor.
쐇 Remove the mounting screws from the old
contactor.
쐋 Mount the new contactor using the screws provided.
Some models include a 138550 Mounting Adapter
Plate for use when replacing competitive controls.
쐏 Reconnect the contact and coil leads to the proper
terminals.
CHECKOUT
Always conduct a thorough checkout when installation is
complete. Restore power supply and operate the contactor
and controlled equipment to assure the contactor pulls in
when the coil is energized and the controlled equipment
operates as intended.
