The condions that follow are applicable to the wiring diagrams.
• The installer makes sure that necessary and not shown protecons 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 connecons from moist condions.
Inducon
Problems with inducon must be prevented. Inducon can cause an interference with the
electronics.
Inducon can have many causes such as:
• Cable lengths
• External sources
• Too many cables together.
Electrical connecons are only permied to an electrical installer or
an electrician.
For installaon and maintenance work the system must be de-
energized.
Always make sure that the protecons comply with the, local or
naonal, laws and regulaons of the country.
Separaon of cables is necessary. This prevents problems with
inducon.
