1. Check the actuator’s nametag for confirmation of:

Torque Rating, Quarter Turn Time, Duty Rating and

Power Supply. Example ‘A’ below is shown for S73

PN: 73-0102-113D5-536

2. Suitably rated wire should be used for actuator voltage

and current rating. 18AWG, 300V minimum, insulated

wire is recommended for all sizes.

3. Field control scheme (supplied by others) should be

compatible with the operation of actuator motor (AC

or DC).

NOTE: Do not parallel wire multiple actuators - refer

to explanation on parallel wiring.

CAUTION

Do not reverse motor instantaneously when it is still

running - Reversing direction to actuator motor when

it is running can cause damage to motor, switches and

gearing. Directional control switching can be done by

PLC in 20ms or by a small relay in 45ms. Therefore

time delay of 1s has to be incorporated into the control

scheme to avoid damage.

NOTICE

18 AWG minimum wire is recommended for all field wiring

4. Actuator must have its field wiring terminated as shown

in the supplied wiring diagram (diagram attached to

inside of cover). Wiring diagrams (AC or DC) show

remote (customer supplied) typical control switching

devices. Refer to customers/field wiring for details of

the specific control devices.

NOTICE

The conduit connections must be properly sealed to main-

tain the weatherproof integrity of the actuator enclosure.

CAUTION

Do not reverse motor instantaneously when it is still

running - Reversing direction to actuator motor when

it is running can cause damage to motor, switches and

gearing. Directional control switching can be done by

PLC in 20ms or by a small relay in 45ms. Therefore

time delay of 1s has to be incorporated into the control

scheme to avoid damage.
