• The operator must be connected to Life control units only.
• All wiring and connection operations must be carried out with the control unit disconnected from the electricity supply. If the
disconnection device is not in view, display a sign reading: “ATTENTION: MAINTENANCE WORK IN PROGRESS”.

The 230 V and 24 V two-cabled versions have an extra cable for the encoder and limit switch signal (2-wired cable).
The 230V models come with a capacitor, which is housed in the control unit. The capacitor is connected in parallel to the “open motor” and “close
motor” cables.
N.B. each cable is 1m long.
