External pulsed resistors

6-194
With externally attached pulsed resistors, the power loss of the resistor that oc-
curs during braking accumulates outside the control cabinet and, thus, does not
place a thermal load on the control cabinet.
The external pulsed resistors are generally required for the 28 kW UI module.
Depending on the power requirement, up to two equal pulsed resistors can be
connected in the case of the 28 kW UI module. The protection function is para-
meterized via the connecting terminals.

Note:
Carefully note the mounting position, base mounting is possible.
When mounting the pulsed resistor it must be carefully ensured that it is not located
in the cooling airflow of the drive group and there is sufficient clearance to the cable
ducts.
