Danger!
Hazardous electrical voltage
The leakage current to earth (PE) is > 3.5 mA AC or > 10 mA DC.
Possible consequences:
ƒ Death or severe injuries when touching the device in the event of
an error.
Protective measures:
Implement the measures required in EN 61800−5−1. Especially:
ƒ Fixed installation
– Implement PE connection in compliance with standards.
– Connect PE conductor twice or PE conductor cross−section
³ 10 mm 2 .
ƒ Connection with a connector for industrial applications according
to IEC 60309 (CEE):
– PE conductor cross−section
³ 2.5 mm 2 as part of a multi−core
supply cable.
– Provide for suitable strain relief.
