Application Notes
I. Always make sure power is off before attempting to work on or near the actuator and its electrical controls.
2. Electrak 10 actuators are load protected with a slip clutch. The clutch will slip when the load exceeds the
actuator’s rating, preventing any movement of the load. The clutch is factory set based on load rating.
3. The duty cycle for the Electrak 10 actuator is 25% “on time”. For instance, an actuator operating for 25 seconds
must remain off for 75 seconds before operating again. Exceeding this maximum will cause the motor to overheat
and trip its internal thermal breaker.
4. Electrak 10 actuators are weather protected for use in outdoor applications, but they are not waterproof and
should not be used in underwater conditions
5. Electrak 10 actuators are not explosion or dust ignition proof; do not use in those types of environments.
6. Electrak 10 actuators are factory lubricated for life. No disassembly is ever required for routine maintenance
purposes.
