earthing

As stipulated in the applicable regulation, the connection to earth contact is compulsory for devices with working voltages exceeding 42V.

The actuator is always powered, so it must be connected to a disconnection system (switch, circuit breaker) to ensure the actuator power
cut, correctly located, easily reached and marked as being the disconnecting device for the equipment.

An Inrush current may occur when actuators are switched on. Therefore it is necessary to limit the number of actuators on the same line.
Alternatively an inrush current limiter at the output of the circuit breaker may be used.

The terminal temperature can reach 90°C

For a use with a long power supply wiring, the induction current generated by the wires mustn't be higher than 1mA

To optimize the installation security, please connect the failure feedback signal (D1 and D2).

In order to ensure the IP66 tightness, the cable gland for feedback wiring must be used (7 to 12mm cable). Otherwise, the cable
gland must be replaced by a ISO M20 IP66 cap.
Instructions
Our cable glands are designed for cables with a diameter between 7mm and 12mm.
The actuator can support MAINS supply voltage fluctuations up to ±10 % of the nominal voltage.
It is necessary to connect all actuators to an electrical cabinet

Remove the position indicator, unscrew the four screws and take off the cover.
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.21 or p.26 for POSI models )

To ensure the correct functioning of the anti-condensation heaters, the actuator must be permanently power supplied
WIRING OF THE FEEDBACK SIGNAL (Except POSI: p.25)
Our actuators are equipped with two simple limit switch contacts normally set either in open position, either in closed position (see wir-
ing diagram DSBA0436). 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.21 (or p.26 for POSI models ).

Tighten the 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, fasten the four screws and attach the position indicator.
