Checking the installation
Connection of other loads
Connection of other loads (for example ventilation or air conditioning enclosure) in parallel on the frequency inverter and the braking unit
with a common circuit-breaker is not permitted (see diagram below). If this is nevertheless performed, then if the circuit-breaker trips, the
connection to the line supply will be absent (loss of power and synchronization information for the braking units). The IGBTs then transfer
the DC voltage directly to the other loads. The resulting quasi-rectangular supply voltage signal sends a current across the loads, whose
waveform and level depend on their impedance. If the power consumption of the loads is too low, then the DC voltage and the output voltage
of the braking unit increase during generation. This overvoltage can damage all the components that are connected.
CAUTION
RISKS OF INTERFERENCE
Overvoltages can cause serious damage to the frequency inverter and/or the braking
unit and the other loads.
Failure to follow this precaution can result in equipment damage.
