5.2 Protection - Conditions and starting points
The conditions that follow are applicable to the wiring diagrams.
• The installer makes sure that necessary and not shown protections are used and included in the
wiring diagrams.
• Make sure that you can see the operated system from all control units and control systems. Put
control units and control systems at a height of more than 1.5 m.
• Protect the electric connections from moist conditions.
Induction
Problems with induction must be prevented. Induction can cause an interference with the
electronics.
Induction can have many causes such as:
• Cable lengths
• External sources
• Too many cables together.
Electrical connections are only permitted to an electrical installer or
an electrician.
For installation and maintenance work the system must be de-
energized.
Always make sure that the protections comply with the, local or
national, laws and regulations of the country.
Separation of cables is necessary. This prevents problems with
induction.
