Electric wiring: instructions
The caps placed on M20x1.5 openings (appendix p.14 mark 7) must be replaced by ATEX/IECEX and IP68 certified con-
nection glands. The unused threaded opening must be closed with ATEX/IECEX and IP68 certified caps
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. 18/19)

To ensure the correct functioning of the anti condensation heater, the actuator must be always supplied
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
wiring diagram DSBL0491 (230V) and DSBL0492&DSBL0493 (400V) 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.

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 18/19

Tighten the ATEX/IECEX and IP68 cable gland (Ensure that it's well mounted to guaranty the proofness).
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.

Re-mount the cover and fasten the four screws.
