B. Power wires:
Power wires connect to
terminals
L1(L), L2, L3 (N), T1, T2, T3, P and N.
Select power wire
in
accordance with the following criteria:
(1) Use wires with copper core only. Insulating materials with diameters
should be
based on
working conditions at

.
(2) The minimum
nominal
voltage of 240Vac type
connectors
is 300V, and 480Vac type
connector
is 600V.
C. Control wire:
Control wire is connected to
the
TM2 control terminal.
