6.1 Important notes
Danger!
Hazardous electrical voltage
Depending on the device, all power connections remain live up to 3 minutes
after the mains has been switched off.
Possible consequences:
ƒ Death or severe injuries when touching the power terminals.
Protective measures:
ƒ Wait for at least 3 minutes before working on the power terminals.
ƒ Make sure that all power terminals are deenergised.
Danger!
Dangerous voltage
The leakage current to earth (PE) is > 3.5 mA AC or > 10 mA DC.
Possible consequences:
ƒ Death or severe injuries when the device is touched in the event of a fault.
Protective measures:
ƒ Implement the actions required in the EN 61800-5-1. Especially:
– Fixed installation of the machine
– PE connection for the controller and the machine must conform to
standards (PE conductor diameter ≥ 10 mm
2
or PE conductor must be
connected twice)
Stop!
No device protection in the event of too high mains voltages
The mains input is not fused internally.
Possible consequences:
ƒ Destruction of the device if the mains voltage is too high.
Protective measures:
ƒ Observe the max. permissible mains voltage.
ƒ Fuse the device correctly on the supply side against mains fluctuations and
voltage peaks.
