Electric wiring: warnings

As stipulated in the applicable regulation, the connection to earth contact is compulsory for devices
with working voltages exceeding 42V.

The actuator is being always under power, it must be connected to a disconnection system (switch,
circuit breaker) to ensure the actuator's power cut. The latter must be closed to the actuator, easy to
reach and marked as being the disconnecting device for the equipment.

The temperature of the terminal can reach 90°C.

In case of long cables, please note the induction current shall not exceed 1mA.

To optimize the installation security, please connect the failure feedback signal (terminals 7 & 8).

The actuator can tolerate temporary overvoltage of the electrical grid up to ± 10 % of its nominal sys-
tem operating voltage.

It is necessary to connect all actuators to an electrical cabinet. The power supply cables must have
the RATED diameter for the maximum current supported by the actuator and comply with IEC 60227
or IEC 60245 standards.

The selection of the cables and cable glands: the maximal operating temperature of the cables and
cable-glands must be at least 110°C.

In order to ensure the IP68 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 IP68 cap. A cable gland is tight
when it has been tighten by one turn ahead of contact between rubber seal and nut.

The auxiliary limit switches must be connected with rigid wires. If the applied voltage is higher than
42V, the user must foresee a fuse in the power supply line.

The feedback switches must be powered with the same voltage. The reinforced insulation of the mo-
tor control allows voltages up to 250V AC/DC.
