5.11.4 Connecting the Control Cable to the Control Terminals
The control terminals are located near the LCP, as shown in Illustration 16 . The control terminal connectors can be unplugged from
the drive for convenience when wiring. Either solid or flexible wire can be connected to the control terminals. For minimum and
maximum control cable cross-section, refer to the
Cable Specifications section.
N O T I C E
ELECTRICAL INTERFERENCE
Minimize interference by keeping control wires as short as possible and separate from high-power cables.
Procedure
Strip 10 mm (0.4 in) of the outer plastic layer from the end of the wire.
Insert the control wire into the terminal.
For a solid wire, push the bare wire into the contact.
For a flexible wire, open the contact by inserting a small screwdriver into the slot between the terminal holes and push
the screwdriver inward. Then insert the stripped wire into the contact, and remove the screwdriver.
Pull gently on the wire to ensure that the contact is firmly established.
Loose control cable can cause equipment faults or reduced performance.
