d. For the quick-connect connector, push the connector on and apply a
quarter turn.
e. For the threaded connector, hand-tighten the knurled collar with five to
six turns to fully seat the connector.
Signal and Wire Definitions
for Flying Lead Components
For linear motors, catalog numbers LX xxxxxxxxxxx0x, wire them by using the
wiring diagram on page 61 . Wire colors and signal types are shown here; for wire
gauge information see LX-Series Iron Core Linear Servo Motor Technical Data,
publication LX-TD001 .
Linear Motor Coil
These are the wire colors and signals for the linear motor-coil power and thermal
protection cables, catalog numbers LX xxxxxxxxxxx0x.

ATTENTION: Be sure that cables are installed and restrained to
prevent uneven tension or flexing at the cable connectors.
Excessive and uneven lateral force at the cable connectors may
result in the connector’s environmental seal opening and closing
as the cable flexes. Failure to observe these safety precautions
could result in damage to the motor or encoder.
ATTENTION: Keyed connectors must be properly aligned and
hand-tightened the recommended number of turns.
Improper alignment is indicated by the need for excessive force,
such as the use of tools, to fully seat connectors.
Connectors must be fully tightened for connector seals to be
effective.
Failure to observe these safety precautions could result in damage
to the motor, cables, and connector components.

ATTENTION: Disconnect the input power supply before installing or
servicing the motor. Motor lead connections can short and cause damage
or injury if not well secured and insulated. Insulate the connections, equal
to or better than the insulation on the supply conductors. Properly ground
the motor per the selected drive manual.
