1 Provide overload protection and disconnect as required.
2 Actuators 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.
3 For end position indication, interlock control, fan startup,
etc., MA4X-715X-502, and MA4X-707X-502 models
incorporate two built-in auxiliary switches.

Figure-1 Typical Wiring Diagram for 24 Vac Basic and Double Auxiliary Switch Models.
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.
