Abbreviations for the Tables
*) Resulting max. brake torque when using R
in brackets is the drives max. brake torque
2
*) All cabling must comply with national and local regulations on cable cross-sections and ambient temperature. Copper
(60/75°C) conductors are recommended.
3
*) Order the specified amount of Brake Resistors (e.g. 2 x 1062 = 2 pieces of 175U1062). See table header for the first four
characters (175U or 130B).
4
*) Rating for each thermistor relay (using one thermistor relay per resistor).
5
*) Parallel star connection (see the Installation chapter).
6
*) Please contact Danfoss for further info.
