Implementing thermal overload and short-circuit
protection
Protecting the drive and input power cable in short-circuits
Protect the drive with fuses (1) and the input cable with fuses (2) or a circuit breaker (3) as
shown below:
Size the fuses or circuit breaker at the distribution board according to local regulations for
the input cable protection. Select the fuses for the drive according to the instructions given
in chapter
The fuses for the drive protection will restrict drive damage and
prevent damage to adjoining equipment in case of a short-circuit inside the drive.
Note 1
: If the fuses for the drive protection are placed at the distribution board and the
input cable is dimensioned according to the nominal input current of the drive given in the
rating table on page
, the fuses will protect also the input cable in short-circuit
situations, restrict drive damage and prevent damage to adjoining equipment in case of a
short-circuit inside the drive. No separate fuses for the input cable protection are needed.
Note 2:
Circuit breakers must not be used without fuses.
Protecting the motor and motor cable in short-circuits
The drive protects the motor cable and motor in a short-circuit situation when the motor
cable is dimensioned according to the nominal current of the drive. No additional
protection devices are needed.
Protecting the drive and the input power and motor cables against
thermal overload
The drive protects itself and the input and motor cables against thermal overload when the
cables are dimensioned according to the nominal current of the drive. No additional
thermal protection devices are needed.
WARNING!
If the drive is connected to multiple motors, use a separate circuit
breaker or fuses for protecting each motor cable and motor against overload. The
drive overload protection is tuned for the total motor load. It may not trip due to an
overload in one motor circuit only.
