• Use exible metal conduit.

• Push the UL listed conduit tting device over the

actuator’s cable to butt against the enclosure.

• Screw in conduit connector.

• Jacket the actuator’s input wiring with UL listed exible

conduit.

• Properly terminate the conduit in a suitable junction box.

Installation Notes for MS41-7303-W02, MS41-7303­WH2

• Use 60 °C/75 °C copper (Cu) conductor and wire size
range 12 (0.9 mm) to 26 (0.4 mm) Ga., stranded or
solid.

• If conduit is used, use UL listed and CSA certied

watertight exible metal conduit, strain relief, and
conduit tting suitable for outdoor applications, rated

NEMA type 4, 4X, 6 or 6X or watertight.

Provide overload protection and disconnect as required.

Actuators may be connected in parallel. See the Mounting
Multiple Actuators on a Common Jackshaft section for

2

complete information. Observe power consumption and
input impedance.

Actuators may also be powered by 24 Vdc.

3

For end position indication, interlock control, fan startup,
etc., MA41-7303-502 incorporates two built-in auxiliary
switches: 2x SPDT, 3 A (0.5 A) @ 250 Vac, UL approved.

4

One switch is xed at +10° and one is adjustable from 10°

… 85°.

Meets cULus requirements without the need of an
electrical ground connection.
