Specifications for the drive wires, safety devices and operating devices are given in the tables below.
For the greatest drive sizes, wiring with multiple conductors for the same phase is recommended. For example,
“2x150” in the wire cross-section column means that two parallel-connected 150sqmm conductors per phase
are used.
Multiple conductors must have the same length and must follow parallel paths so that current is evenly
delivered at any frequency level. Unparallel paths, even if their length is the same, result in uneven current
distribution at high frequency.
