TROVIS 6412 (panel-mounting unit)

5. Electrical connections

When making the electrical connections, note the VDE 0100 regulations and the regulations
valid in the country where the control station is intended to be installed.
Use shielded cables for the signal lines of the analog and binary inputs, which are installed
outside the control cabinets, in order to avoid measuring errors or other interferences. Inside
the control cabinets, these lines have to be installed separately from the control and power
supply lines.
The shieldings of the lines are to be grounded on one side at the neutral point of the measuring
and control system.
