Use at ambient temperatures below -20 °C

The rotary drives are equipped with integrated, regulated heating for use at ambient temperature down to -40 °C. The heating is supplied automatically when there is a constant voltage supply to terminals 1 and 2.

1. Once the rotary drive is installed, it must be connected to the electrical system immediately.
2. The heating switches on automatically if the rotary drive reaches an internal temperature of -20 °C. It warms the rotary drive up to operating temperature then switches off automatically. The rotary drive will not move during this heating up phase.
3. Actuation and standard function are only ensured after this heating up period.
