Braking resistors
9.1 Description
Installation
The braking resistors can be installed standing on the floor of the control cabinet or
suspended. You must ensure that the braking resistors do not obstruct the flow of cooling air
to the drive line-up.
Positioning the braking resistor outside the control cabinet or switchgear room enables the
resulting thermal losses to be routed away. This reduces the level of air conditioning
required.
Connection cables
A shielded connecting cable (3 m, 3 x 1.5 mm
1AA00-0DA0.
All other braking resistors are supplied without a connection cable. The maximum conductor
cross-sections are listed in the technical data.
The maximum cable length for all braking resistors is 10 m.
