88 Guidelines for planning the electrical installationImplementing thermal overload and short-circuitprotection Protecting the drive and input power cable in short-circuitsThe drive is equipped with internal AC fuses as standard. Protect the input cable withfuses or a suitable circuit breaker. Size the input cable fuses according to the instructionsgiven in chapter Technical data. The fuses will protect the input cable in short-circuitsituations, restrict drive damage and prevent damage to adjoining equipment in case of ashort-circuit inside the drive. Protecting the motor and motor cable in short-circuitsThe drive protects the motor cable and motor in a short-circuit situation when the motorcable is sized according to the nominal current of the drive. No additional protectiondevices are needed. Protecting the drive and the power cables against thermal overloadThe drive protects itself and the input and motor cables against thermal overload when thecables are sized according to the nominal current of the drive. No additional thermalprotection devices are needed.WARNING! If the drive is connected to multiple motors, use a separate circuitbreaker or fuses for protecting each motor cable and motor against overload. Thedrive overload protection is tuned for the total motor load. It may not trip due to anoverload in one motor circuit only. Protecting the motor against thermal overloadAccording to regulations, the motor must be protected against thermal overload and thecurrent must be switched off when overload is detected. The drive includes a motorthermal protection function that protects the motor and switches off the current whennecessary. Depending on a drive parameter value, the function either monitors acalculated temperature value (based on a motor thermal model) or an actual temperatureindication given by motor temperature sensors. The user can tune the thermal modelfurther by feeding in additional motor and load data.The most common temperature sensors are:• motor sizes IEC180…225: thermal switch, eg. Klixon• motor sizes IEC200…250 and larger: PTC or Pt100.See the firmware manual for more information on the motor thermal protection, and theconnection and use of the temperature sensors.Protecting the drive against ground faultsThe drive is equipped with an internal ground fault protective function to protect the unitagainst ground faults in the motor and motor cable in TN (grounded) networks. This is nota personnel safety or a fire protection feature. The ground fault protective function can bedisabled with a parameter, refer to the firmware manual.An optional ground fault monitoring device (+Q954) is available for IT (ungrounded)systems. The option includes a ground fault indicator on the drive cabinet door.
