B. Power wires
Power wires are wires connected to L1, L2, L3, T1, T2, T3, P and R. Choose wires in
accordance with the following criteria:
(1) Use wires with copper cores only. Decide diameters of wires based on working conditions at
105
o
C.
(2) For nominal voltage of wires, the minimum voltage of 240VAC type is 300V, and 480VAC
type is 600V.
C. Control
wire
Control wire is connected to TM2 control terminal. Choose the wire in accordance with the
following criteria:
(1) Use wires with copper cores only. Decide the diameter of the wire based on working
conditions at 105
℃
.
(2) For nominal voltage of wires, the minimum voltage of 240VAC type is 300V, and 480VAC
type is 600V.
(3) To avoid noise interference, do not route the control wire in the same conduit with power
wires and motor wires.
D. Nominal electrical specifications of the terminal base: The following are nominal values of TM1:
