5- Installation recommendations

Experience shows that the functional efficiency of the system basically depends on
the quality of the installation:

- Interference suppression,

- Choice of operating frequency,

- Marking of the controlled equipment,

- Position of receiver and antenna,
- Quality of wiring of receiver and associated systems,
- Electrical power supply protection,
- Minimum and maximum current of relay outputs.
5.1- Interference suppression
In the event of inductive loads on the relay outputs (contactor coils, solenoid valves
or electro-brakes), interference suppression devices such as capacitors, RC circuits,
diodes, etc. must be placed directly at the terminals of the controlled components
using the shortest possible connections.

5.2- Choice of operating radio frequency

The 64 radio channels in 433-434MHz or 12 in 869MHz of the UC provide a broad
range of choices among the available frequencies. To ensure good operating
quality, it is important that the radio channel used be free throughout the area in
which the machine will be controlled.
If several radio remote controls are operating on the same site, frequencies spaced
by at least two radio channels (for example: 5, 7, 9 ...) should be used and, if
necessary, a frequency plan should be drawn up, specifying the various machines
controlled and their working frequency.
5.3- Marking of the controlled equipment
If there are several equipment fitted with similar radio remote control systems working
in the same neighbourhood (e.g. in a plant), each transmitter shall carry a clear
indication which tells the equipment driver which equipment is controlled by the
transmitter in question.
