Cables
Motor power cable
When selecting the motor power cable, observe the following:
●
Cross section: The minimum size depends on the type current and rout‐
ing method of the motor power cable.
●
Leakage capacitance: Without HLL DC bus choke, maximum 500 nF
per phase is permitted (phase: HMU + HNL + HNC + HNL + HNF).
When connecting multiple HMUs in parallel, the allowed leakage capaci‐
tance drops to 450 nF per phase. Reason: balancing HNF mains filter.
The overall leakage capacitance for n parallel HMUs is therefore n x 450
nF.
