The connection cable and the ul-
tra-low-voltage safety cables (con-
trols, electric lock, antenna, power
supply for auxiliaries) must be sep-
arated (minimum 4 mm in air or
1 mm through supplementa-
ry insulation) from the 230V ~

Position jumper J7 on TTL.
If NET-COM is installed at more than 3 m
from the device, it is necessary to use the
S-EXTENDER accessory (art. 677650): this sig-
nal amplifier allows for reaching a maximum
distance of 50 m by using a 3x1 mm shielded
cable.
In this configuration, position jumper J7
on 485.
