4.2 Protective insulation
Danger!
Dangerous electrical voltage
If Inverter Drives 8400 are used on a phase earthed mains with a rated mains
voltage ≥400 V, external measures need to be implemented in order to provide
reliable protection against accidental contact.
Possible consequences:
• Death or serious injury
Protective measures:
• If protection against accidental contact needs to be provided for the control
terminals of the controller and for 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 protective insulation provided in Inverter Drives 8400 is realised in
accordance with EN 61800-5-1.

Note!
The INTERBUS input (X206) is isolated from the voltage supply (X205) and the
INTERBUS output (X207).

Example
Which type of protective insulation is used between the bus terminal of the device module
in slot MCI and the mains terminal X100?
The separate potential area with the better protective insulation is decisive.
– The separate potential area of the device module bus terminal is "functionally
insulated".
– The separate potential area of the mains terminal has a "reinforced insulation".
Result: The insulation between the mains terminal X100 and the bus terminal is of the
"reinforced insulation" type.
