Protection against contact
• All terminals have basic isolation (single insulating distance)
• Protection against contact can only be ensured by additional measures (i.e. double insulation)
STOP!
In the case of a Spinning Motor:
To bring free-wheeling loads such as fans to a rest before starting the drive, use the DC
injection braking function (“Auto-DCB”). Starting a drive into a freewheeling motor creates
a direct short-circuit and may result in damage to the drive.
Conrm motor suitability for use with DC injection braking.
3.2.4 Control terminals
STOP!
If the kVA rating of the AC supply transformer is greater than 10 times the input kVA rating of the drive(s),
an isolation transformer or 2-3% input line reactor must be added to the line side of the drive(s).
