8.2 Positioning the antenna
The Receiving Unit may be configured with internal antenna or external antenna
(see Technical Data Sheet). If the antenna is external, it cannot be mounted
directly on the Receiving Unit's casing, but it mu be inalled with the antenna
cable-extension kit.
8.3 Wiring
Wiring inside the Receiving Unit shall be made with electrical wires resiant
to at lea 125°C usage temperature.
Group all cabling wires so that they are far from the radio area in the electronic
board, in order to avoid interference and danger related to electrical safety.
The current of STOP outputs is interrupted at regular intervals for approx. 1
ms every 100 ms. Risk assessment mu consider this interruption. If STOP
outputs are used to power electronic devices, check that they are compatible
with this recurring interruption (use suitable filters if necessary).
When failure is detected on the SAFETY outputs, the STOP outputs are
automatically opened within 200 ms. Risk assessment mu consider this
delay.
SAF_1 and SAF_2 outputs are designed to drive power loads and are protected
by means of fuses and transils, to ensure the longe lifetime in mo
applications.If these outputs are connected to inductive loads (i.e. solenoid
valves, relays), it is recommended to connect a reverse recovery diode close
to the load, to further reduce the effects of demagnetisation currents.
