5.1 Important notes
Danger!
Dangerous voltage
All power terminals remain live for at least three minutes after mains
disconnection.
Possible consequences:
ƒ Death or severe injuries when touching the power terminals.
Protective measures:
ƒ Wait for at least three minutes before working on the power terminals.
ƒ Check that all power terminals are deenergised.
Danger!
Dangerous voltage
The discharge 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
– PE connection must confirm 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.
