3.3 Positioning the antenna
The antenna is inside the receiving unit. Hence, install the receiving units
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 possibly towards
the work 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.
To obtain the protection from unintended movements from the rest position,

commands.
The STOP circuit in the receiving unit has two contacts connected in series
through a wire jumper (manufacturer's standard wiring). If the machine needs
a STOP circuit with two separate contacts (four wires), this bridge can be
removed. In this case, the installer is responsible for wiring in a way that
assures the required safety level.
