*) The setting of the overcurrent release results from the maximum permissible
brake current of the resistor (r.m.s. valuel.
Overcurrent release and base are not supplied with the inverter.
Base for thermal overcurrent release: Part no. 325 701
Warning: In ca se of mains overvoltage (>260 VI, the brake chopper may be
activated. When using resistors without overload protection, the
resistors may burn out. Therefore, only resistors with integrated or
external temperature surveillance may be used. Since the surface of the
brake resistors may heat up to 350°C, the resistors must be built into a
fire-proofhousing.
The brake chopper output isnot protected against short-circuits.
