WARNING
Electrical Power Hazard.
Line voltage can cause death or serious injury
and short equipment circuitry.
Disconnect power supply before installation.
CAUTION
Electrical Shock or Equipment Damage Hazard.
Low voltage can shock individuals or short
equipment circuitry.
Disconnect power supply before installation.
CAUTION
Equipment Damage Hazard.
Tightly securing actuator to damper housing can
damage actuator.
Mount actuator to allow it to float along its vertical axis.
CAUTION
Actuator Damage Hazard.
Using actuator as shaft bearing causes device
damage.
Use actuator only to supply rotational torque. Avoid
any side loads to actuator output coupling bearings.
IMPORTANT
1. All wiring must comply with local electrical codes,
ordinances and regulations.
2. Voltage and frequency of transformer used with
ML8202 and ML8302 must correspond with the
characteristics of power supply and actuator.
3. Use wires rated for at least 75°C (167°F).
4. For actuators with a product date code before 0527,
a power break of less than two seconds can cause
the actuator to spring-return 5 degrees or less and
remain in place until a power break of longer dura-
tion. For actuators with a product date code of 0527
or after, a power break of any duration will cause the
actuator to spring-return and be able to drive imme-
diately when power is reapplied.
