Danger!
Hazardous electrical voltage
All power connections carry a hazardous electrical voltage for a longer time
after mains disconnection. Observe the information regarding the discharge
time on the device.
Possible consequences:
ƒ Death or severe injuries when touching the power terminals.
Protective measures:
ƒ Before working on the power connections, wait at least until the discharge
time has passed (depending on the device, this may be up to 30 minutes).
ƒ Make sure that all power terminals are deenergised.
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 10 mm
2
.
ƒ Connection with a connector for industrial applications according to
IEC 60309 (CEE):
– PE conductor cross−section 2.5 mm
2
as part of a multi−core supply cable.
– Provide for suitable strain relief.
