Danger!
Dangerous voltage
If the Inverter Drives 8400 are operated on a phase-earthed mains with a rated 
mains voltage of  400 V, external measures need to be implemented in order to
ensure protection against accidental contact.
Possible consequences:
 • Death or severe injury
Protective measures:
 • If protection against accidental contact is required for the control terminals 
of the controller and the connections of the plugged-in device modules, ...
– a double isolating distance must exist.
– the components to be connected must be provided with the second 
isolating distance.
Note!
The existing protective insulation in the Inverter Drives 8400 is implemented
according to EN 61800-5-1.
