X89: Braking
resistor
Connection at the UEC 11x:
On the UEC 11x compact inverters, there must be no bridge at connector X89.
A bridge at X89 would cause the internal braking resistor to be bridged and
lead to a short circuit of the DC-link voltage. If necessary, you can connect an
external braking resistor (PW 210) via X89 in parallel to the internal braking
resistor.
