General wiring guidelines
Please note:
}
The requirements of the supply voltages can be found in the chapter entitled "Technical
Details".
}
Protective separation must be ensured for the external power supplies that generate
the supply voltages. Failure to do so could result in electric shock.
}
The external power supplies must comply with the current applicable standard EN
60950-1, EN 61140, EN 50178 or EN 61558-1.
}
The maximum current load for the periphery supply on the module bus is 10 A. Please
refer to the derating diagram in the chapter entitled "Function Description".
}
Earth the 0 V supply on the periphery supply or monitor each supply group for earth
faults.
}
The connection of the 0 V supply to the central earth bar or earth fault monitor must be
in accordance with relevant national regulations (e.g. EN 60204-1, NFPA 79:17-7,
NEC: Article 250).
}
Details of the minimum range for conductor cross sections on connection terminals can
be found in the section entitled "Technical Details".
}
Use copper wiring.
