contacts or wheel type collectors.
1. See section 11.3 for minimum cross-section and max. length of supply cable.
2. Select cables, leads and conductor lines to match the existing operating conditions
(e.g. voltage, current, protection against electric shock, amassment of cables and
leads) and for external influences (e.g. ambient temperature, presence of water or
corrosive materials, mechanical stress).
