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.
Stop!
The device contains components that can be destroyed by electrostatic
discharge!
Before working on the device, the personnel must ensure that they are free of
electrostatic charge by using appropriate measures.
