d. For the threaded connector, hand-tighten the knurled collar with five to
six turns to fully seat the connector.
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.
