BRAKE RESISTOR CABLES
Vacon
®
NXS and NXP AC drives have terminals for the DC supply and an optional external
brake resistor. These terminals are identified with B–, B+/R+ and R–. The DC bus connection
is made to terminals B– and B+ and the brake resistor connection to R+ and R–. You can find
the dimensions that we recommend for the brake resistor cables in the tables in Chapter 5.3
Cable dimensioning and selection.
CAUTION!
If you use a multi-conductor cable, 1 of the conductors of the brake resistor cable
stays unconnected. Cut off the remaining conductor to prevent an accidental
contact with a conducting component.
See Chapter 9.1.5 Brake resistor ratings.
NOTE!
The frames FR8 and larger have the DC connection as optional.
NOTE!
If it is necessary to connect an external brake resistor, see Brake Resistor Manual.
