1Provide overload protection and disconnect as required.
2Actuators mounted on separate shafts may be wired in parallel. All actuator black wires are connected to the transformer common and all red wires are connected to the hot lead. Power consumption must be observed.
3For end position indication, interlock control, fan startup, etc., MA4X-715X-502, and MA4X-707X-502 models incorporate two built-in auxiliary switches.
MX40-707X-502 and MX40-715X-502 units manufactured prior to the date code 0141 (October 6, 2001) used the following color coding for the auxiliary switches:
Auxiliary Switch 1 |
|
Orange: |
Fixed auxiliary switch common (com) |
Yellow: |
Fixed auxiliary switch normally closed (NC) |
Violet: |
Fixed auxiliary switch normally open (NO) |
Auxiliary Switch 2 |
|
Orange/white: |
Adjustable auxiliary switch common (com) |
Violet/white: |
Adjustable auxiliary switch normally closed (NC) |
Yellow/white: |
Adjustable auxiliary switch normally open (NO) |
The label information on these units is incorrect. If replacing these units, the auxiliary switch operation of the replacement actuator will be per the product label.

Precautions General
Warning:
•Electrical shock hazard! Disconnect the power supply (line power) before installation to prevent electric shock and equipment damage.
• Make all connections in accordance with the job wiring diagram and in accordance with national and local electrical codes. Use copper conductors only.
Caution:
•Avoid electrical noise interference. Do not install near large contactors, electrical machinery, or welding equipment.
•Do not drill holes in actuator body. Six pre-drilled holes are located on each side, under the label, to accept #10-24 thread-forming screws for mounting accessories.
Caution: The MX41-707X and MX41-715X actuators are equipped with a manual override.
•The manual override is to be used only when power is not applied to the unit.
•If the universal clamp is not set to 0° on the position indicator, manually wind the actuator in the direction indicated with hex wrench from -5° to 0° and lock with a screwdriver.
•When operating manual override, back off 5° from full open mechanical stop to ensure proper release.
•Do not attempt to use the manual override with actuators mounted in tandem. Damage to the gear train may occur.
