
Use only one relay for one actuator.

As stipulated in the applicable regulation, the connection to earth contact is compulsory for devices with working voltages
exceeding 42V.

In order to prevent electrostatic discharge, the external the housing must be connected (see p. 31 rep. 17) to earth The
cross-section must be at least 4 mm

The actuator is being always under power, it must be connected to a disconnection system (switch, circuit breaker) to en-
sure the actuator's power cut. The latter must be closed to the actuator, easy to reach and marked as being the discon-
necting device for the equipment.

The temperature of the terminal can reach 90 °C.

To optimize the installation security, please connect the failure feedback signal (standard: D1/D2, BBPR/GFS : D3/D4 et
GPS : 67/68).

In case of long cables, please note the induction current shall not exceed 1mA.

The actuator can tolerate temporary overvoltage of the electrical grid up to ± 10 % of its nominal system operating voltage.

The selection of the cables and cable glands: the maximal operating temperature of the cables and cable-glands must be at
least 110 °C.

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 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 motor control allows volt-
ages up to 250V AC/DC.
