B. Power cables:
Power cables are wires connected to L1(L), L2, L3 (N), T1, T2, T3, P and N. Choose cable in
accordance with the following criteria:
(1) Use cable with copper cores only. Select cable with insulation diameter based on working
conditions at 105P

C.
(2) For nominal voltage ratings, use cable rated at minimum 300V for 240Vac iDrives and
600V rated cable for 480Vac iDrives.
C. Control cables:
Control cables are connected to TM2 control terminals. Choose cable in accordance with the
following criteria:
