3.2.11. Braking Resistors for BU200 4T

NOTE

The wire cross-sections given in the table relate to one wire per braking resistor.

NOTE

The Part Numbers of the braking resistors in the tables are given in the

Available Braking Resistors section.

CAUTION

The cables of the braking resistors shall have insulation features and heatresistance features suitable for the application. The minimum rated voltage of the cables must be 0.6/1kV.

HOT

SURFACE

Based on the functioning cycle, the surface of the braking resistors may reach 200°C.

CAUTION

CAUTION

The power dissipated by the braking resistors may be the same as the rated power of the connected motor multiplied by the braking duty-cycle; use a proper air-cooling system. Do not install braking resistors near heatsensitive equipment or objects.

Do not connect to the inverter any braking resistor with an Ohm value lower than the value given in the tables.

CAUTION

Never exceed the maximum operating time of the resistor as given in the

Available Braking Resistors section.
