the device to be controlled, proceed with wiring and earthling.
4.2
The wiring diagrams are reported both in the attached technical bulletin and on
the plate inside the cover.
4.3
Warning! Before servicing make sure, that power supply is disconnected by
means of the two-pole-switch (phase and neutral); in case of non-observance,
damages to people and to the equipment may occur.

All wires must comply with local prescriptions and, in any case, their section
must be ranging between 1 and 1.5 mm². Connection piping recommended
HO7V-U...G 1.5 mm².
4.7
The wiring diagrams show the AR2 gear motor at end position closed (0°).
4.8
The auxiliary microswitches are single-pole double through and are voltage-free.
4.9
The auxiliary microswitches rating is 5(1)A/250 Va.c.

If a potentiometer is installed, its resistance value is indicated on the label.
4.11
Make sure that power supply and system frequency corresponds to the values
indicated on the AR2 gear motor's plate.

they are laid in a single channel, screened cables must be used.
