3.1 Location

The actuator should be mounted above the valve with sufficient space to remove the terminal cover and

general ease of access. When selecting the location, make sure that the actuator is not exposed to an

ambient temperature exceeding the range -10°C to + 55°C. Humidity <95%. The actuator is rated at IP66.

Warning

Prevent access by non technical personnel!
