Through the Conduit Openings
Depending on the M91xx Series model selected, use
one or both conduit openings. The threaded actuator
conduit openings accept 1/2 in. trade size conduit
fittings. Refer to Figure 6 and proceed as follows:
Models with the same torque and control input may be
mounted in tandem. For example:
• M9116: two GGx, two HGx, or one GGx and
one HGx
1. Loosen the cover screw with a Phillips No. 1
screwdriver, and remove the actuator cover.
• M9124: two AGx, two GGx, two HGx, or one GGx
and one HGx

• M9132: two AGx or two GGx
Note: Do not use M9108 Series models in
tandem.
The Master/Slave Jumper is factory set in the master
position. Determine the method for mounting the two
actuators in tandem: front-to-back (Figure 7 shows the
front view) or back-to-back, and proceed as follows:

2. Push the plastic plug out of the conduit opening
with fingertip.

3. Use the Phillips screwdriver to puncture a hole
through the center of the plug, and reinsert the
plug into the conduit opening.
Note: For applications requiring metal conduit,
thread the conduit fitting into the conduit opening and
hand tighten.
IMPORTANT: Use flexible metallic tubing or its
equivalent with the fitting. Do not overtighten the
conduit fitting into the actuator to avoid damaging
the actuator threads.
4. Insert the cable wires through the plastic plug or
conduit fitting, and connect to the terminal block
using the applicable wiring diagrams in Figure 5.
5. Perform the procedures appropriate to the specific
application, as described in the Tandem Operation
and Setup and Adjustments sections.

6. Reattach the cover and tighten the cover screw.
1. Designate one actuator as the master, and move
Master/Slave Jumper on the other actuator to the
slave position.
Tandem Operation
The tandem configuration provides twice the torque of
a single actuator as follows:
2. Connect Terminal 101, Terminal 102, and
Terminal 103 from the master actuator to the
corresponding terminals on the slave actuator.
(Refer to Figure 7 for AGx models and Figure 8 for
GGx and HGx models.)
• 280 lb·in (32 N·m) for two M9116-GGx or
M9116-HGx units
• 420 lb·in (48 N·m) for two M9124-GGx or
M9124-HGx units
a. When mounting two actuators front-to-back on
the same shaft, connect:
• 560 lb·in (64 N·m) for two M9132-GGx or
M9132-HGx units
• Terminal 101 from the master actuator to
Terminal 101 on the slave actuator.
The actuators operate in exact synchronization,
ensuring the load is split evenly between each unit.
