Separate control cable ducts
￭
Put 24 V DC and 230 V AC (120 V AC) control cables in separate ducts, unless the 24 V DC
cable is insulated for 230 V AC (120 V AC) or insulated with an insulation sleeving for
230 V AC (120 V AC).
Protecting the drive, input power cable, motor and motor
cable in short circuit situations and against thermal
overload
Protecting the drive and input power cable in short-circuit situations
￭
The drive is equipped with internal AC fuses (1) as standard. The fuses restrict drive damage
and prevent damage to adjoining equipment in case of a short-circuit inside the drive.
Protect the input cable with fuses or circuit breaker (2) according to local safety regulations,
appropriate input voltage and the rated current of the drive (see chapter
data (page 197)
).

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.
