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.
The actuator is being always under power, it must be connected to a disconnection system (switch, circuit break-
er) 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.
To optimize the installation security, please connect the failure feedback signal (D1 and D2).
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 operat-
ing 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 stand-
ards.
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 voltages up to 250V AC/DC.
