Electric connection (models without positioning)

SUPPLY AND CONTROL WIRING

Ensure that the voltage indicated on the actuator ID label corresponds to the voltage supply.

Connect the wires to the connector in accordance with the required control mode. (see diagram p. 25)
WIRING OF THE FEEDBACK SIGNAL
Our actuators are equipped with two simple limit switch contacts normally set either in open position, either in closed
position (see DSBL0470 wiring diagram inside the cover). As per factory setting, the white cam is used to detect the open
position (FC1) and the black cam is used to detect the closed position (FC2).
The auxiliary limit switches must be connect with rigid wires. If the applied voltage is higher than 42V, the user
must foresee a fuse in the power supply line.
The voltages applied to each feedback switch (FC1 and FC2, SNAA690000 electronic board) must be exactly the
same. The reinforced insulation between the feedback signal and the motor control authorizes voltages up to
250V AC/DC.

Unscrew the right cable gland and insert the cable.

Remove 25mm of the cable sheath and strip each wire by 8mm.

Connect the wires to the terminal strip in accordance with the diagram p. 25.

Tighten the cable gland (Ensure that it's well mounted to guaranty the proofness).
HEATING SYSTEM WIRING
Power the terminals 10 and 11 (24 V, 110 V or 230 V according the version).
SETTING OF END LIMIT SWITCHES
The actuator is pre-set in our factory. Do not touch the two lower cams in order to avoid any malfunctioning or even damage
to the actuator.
To adjust the position of the auxiliary contacts, make rotate the two superior cams by using the appropriate wrench.
To ensure the correct functioning, the power supply (1, 2, 3, 4) and heating system terminals must be
permanently powered.
In case of low temperature (< -20 °C), the actuator must be powered 3 hours before using (terminals 1-2-
3-4 and 10-11). This time is necessary for the enclosure to reach functioning temperature.
