Planning the electrical installation 57
Implementing thermal overload and short-circuit protection
Protecting the drive and input power cable in short-circuits
Protect the drive and input cable with fuses as follows:
Size the fuses at the distribution board according to instructions given in chapter
on page
. The fuses protect 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.
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 sized 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 sized according to the nominal current of the drive. No additional
thermal protection devices are needed.
Protecting the motor against thermal overload
According to regulations, the motor must be protected against thermal overload and
the current must be switched off when overload is detected. The drive includes a
motor thermal protection function that protects the motor and switches off the current
when necessary.
The most common temperature sensors are:
• motor sizes IEC180…225: thermal switch, eg, Klixon
• motor sizes IEC200…250 and larger: PTC or Pt100.
