2. Adjust the Limit Switches, MDPI (Mechanical Dial Position
Indicator) and Potentiometer following the procedures outlined
in Sections 4.5 and 4.7.
3. Ensure Torque Switch is set properly for your application. In
most cases, adjustments are not needed, but if changes are
required, see Section 4.6, “Torque Switch Settings and Wiring”.
4. Connect wiring to Terminal Strips provided on the actuator.
Refer to the wiring diagram supplied with your specific actuator.
“Fork-type” terminal connections are recommended.
5. Be sure any unused conduit entrances are plugged with metal
Conduit Pipe Plugs.
Notes:
a) Explosion-proof actuators require approved “sealing fittings”
installed in accordance with the National Electric Code.
b) Submersible actuators require approved “sealing fittings” in
order to prevent water entering the actuator.
6. Attach grounding wire to Grounding Lug (piece 14).
