IMPO
RTANT: The D- Series actuators are
intended to control equipment under normal
operating conditions. Where failure or malfunction of
a D- Series actuator could lead to an abnormal
operating condition that could cause personal injury
or damage to the equipment or other property, other
devices (limit or safety controls) or systems (alarm
or supervisory) intended to warn of, or protect
against, failure or malfunction of the D- Series
actuator must be incorporated into and maintained
as part of the control system.
To
mount the actuator, proceed as follows:
1. Press
and hold the gear release lever, and rotate
the
coupler to the 0 or 90° position. Release the
gear
release lever. (See Figure 1.)
Parts Included
Note: is the distance from the center of the
holes in the anti-rotation bracket to the center
