ELECTRICAL SHOCK HAZARD.To avoid serious personal
injury, property damage, turn off ALL power to the actuator
before removing the cover.
Before installation, verify the nameplate information informa-
tion to insure the correct model number and voltage of the
actuator.
Be sure to completly review the actuator manual prior to
operation.
Final limit switch adjustment MUST be done after mounting
the actuator to the valve. Incorrect adjustment may cause
actuator failure.
Over torque switches are factory set. Tampering with the over
torque switch settings may damage the actuator and void the
warrenty.
To minimize the possible damage caused by condensation,
be sure to energize the heater.
Care should be taken when wiring 3 phase actuators.
Conrm proper rotation and limit switch shut-off function
during the initial operation. If the actuator rotates in the
reverse direction, then the phasing needs to be corrected
by switching two of the 3 phase wires on the terminal block.
CAUTION
Explosion-proof products must be used under the
temperature and environment appropriate for the product
spec.
Explosion proof actuators and wiring must be properly sealed
prior to operation. Improper installation may cause
a hazardous condition and failure of the explosion proof
enclosure. The manufacture is not responsible for any losses
or damages caused by incorrect installation.
