Warnings for installation
AUTEC - Air series
3.3 Positioning the antenna
The antenna is inside the receiving unit. Hence, install the receiving unit
towards the working area, so that shields, structures or materials do not
obstruct the radio link. In particular, the receiving unit must be placed at
least 50 cm far from metal objects in its surroundings and never inside
closed metal containers.
WARNING: If the receiving unit is shielded by metal structures or is installed
inside metal cabinets, use the appropriate extension kit for the antenna. In
this case, install the antenna in a vertical position, and if possible towards
the working area.
If this warning is disregarded, the radio remote control working range may be reduced.
3.4 Wiring
The power supply of the receiving unit must be connected using an omnipolar
switch with a switch-contact gap of at least 3 mm, that allows power supply
disconnection during installation, wiring and/or maintenance operations.
The receiving unit's power supply shall be protected from short circuits by
means of a device ensuring a suitable interruption performance (e.g. fuse).

STOP outputs: they shall not exceed the maximum permitted values (see
technical data of the receiving unit).
