M9216 Series Electric Spring Return Actuators Installation Instructions
With the M9000-100 Conduit Adaptor (Included)
To use a conduit adaptor, proceed as follows:
1. Push the plastic plug out of the conduit opening
with fingertip.
2. Slide the capture nut into the slot located inside of
the conduit opening. (See Figure 10.)

3. Insert the conduit adaptor into the conduit opening,
and hand tighten by turning in a CW direction as
shown in Figure 11.

IMPORTANT:
Use flexible metallic conduit or its
equivalent with the fitting. Do not overtighten the
conduit adaptor assembly into the actuator to avoid
damaging the actuator housing.
4. Insert the conduit fitting (not provided) into the
adaptor, and hand tighten in a CW direction.
(See Figure 11.)
5. Insert the cable wires through the conduit adaptor
assembly, and connect to the terminals using the
wiring diagrams in Figure 8.
6. Tighten the clamp on the conduit fitting.
Tandem Operation
The tandem configuration provides 280 lb∙in (32 N∙m),
twice the torque of a single unit. The actuators operate
in exact synchronization, ensuring the load is split
evenly between each unit.
Use two actuators from the same model group (BGx,
GGx, or HGx) for tandem operation. BGx models must
be wired in parallel for tandem operation. GGx models
employ Mode Switch 5, and HGx models employ
Jumper W4.
IMPORTANT:
When connecting two actuators back-
to-back on the same shaft, set the coupler on one
unit to spring return in the opposite direction from the
other unit. (Refer to the
Installation, Spring Return
Direction
section.)
Note:
Manual override does not function after the
actuators configured for tandem operation are
mounted to a shaft.
GGx Models
GGx models are factory set with Mode Switch 5 in the
master position. Designate one unit as the master
actuator. Refer to Figure 12, and proceed as follows:
