Page 9: General
General Description In converters with no regenerative feedback capability, the energy that occurs in the drive train under regenerative conditions is fed back to the DC link where it is reduced via braking resistors. The braking resistor is connected to the Braking Module. The distance between the Braking Module and braking resistor must not exceed 100 m. - Page 10 General WARNING Risk of fire and damage to equipment due to short-circuit/ground fault The cables to the braking resistor must be routed so that a ground fault or short circuit can be ruled out. A ground fault can result in fire with the associated smoke. •...

Electrical installation Cable lugs Cable lugs The cable connections on the devices are designed for cable lugs according to DIN 46234 or DIN 46235. For connection of alternative cable lugs, the maximum dimensions are listed in the table below. These cable lugs are not to exceed these dimensions, as mechanical fastening and adherence to the voltage distances is not guaranteed otherwise. -
