5 Tips to extend PA-17 lifespan: -Install the actuator in a configuration so that the force being experienced by the shaft is at the correct angle and position that line up with the push and pull direction of the actuator's travel path. -Ensure the force that is being experienced by the actuator's shaft is within the force rating of the unit you selected. -Allow the PA-17 actuator to have sufficient off time to cool down so that the motor does not overheat by staying within the 25% duty cycle rating (5 minutes on, 15 minutes off). -Install the actuator in a configuration that allows for the actuator to fully extend and fully retract completely so that it can reach the internal limit switches at the end of travel. -Avoid water damage by using the PA-17 actuators within their ingress protection ratings of IP65. Actuators with IP65 can be stored outdoors in the rain, however, they are not rated to operate in motion while it is raining. To operate in motion while exposed to water, a rating of IP65M or higher is required.
