Power wires:
Power wires are connecting to L1, L2, L3, T1, T2, T3, P, BR and P1. Choose wires in
accordance with the following criteria:
(1) Use copper wires only. Deciding diameters of wires should be based on rating working at
105
o
C.
(2) For rating voltage of wires, the minimum voltage of 230VAC type is 300V, and 460VAC
type is 600V.
(3) For safety reason, the power wires should be fixed by type terminal.
C.
Control wires:
Control wires are wires connecting to TM2 control terminal. Choose the wire in accordance with
the following criteria:
(1) Use copper wires only. Deciding diameters of wires should be based on rating working at
105
o
C.
(2) For rating voltage of wires, the minimum voltage of 230VAC type is 300V, and 460VAC
type is 600V.
(3) To avoid noise interference, do not route the control wires in the same conduit with power
wires and motor wires.
