1． Power cable connection
1) Connection to Power Supply
When connecting the power supply connector to the control box, the connector should be completely
plugged in the proper receptacle after confirming the connector type and matching direction.
A. In case of three-phase electrical power system, the “U” phase should be connected to the red lead
he “V” phase to the white lead, and the “W” phase to the black lead. The motor rotary direction
t
depends, however , upon the setting of the internal switch in the control box as described in
Paragraph 1-(3)
CAUTION: The green wire must be connected to the ground terminal in order to ground
the motor properly.
B
he appropriate power fuse capacity is as follows. Power supply 200V-240V： 10A
. T
100V-120V： 15A
2) Lamp Leads
A.
When installing the illuminating lamp(6V,15-20W),The connecting wire is attached on the back of
the Control box. It should be
removed and connected by
removing the insulating tube
from the wire and stripping
properly. The wire connections
,
should be, then, insulated by
wrapping insulating tape on the wires.
CAUTION: The power switch must be Turned off before connecting the lamp.
B. When the illuminating lamp is not used, the end of the lamp leads must be insulated as (a) or (b) as
— 2 —
shown in the figure on right side. If a short circuit occurs failing to insulate, the transformer in the
control box will be possibly burned out.
CAUTION: The illuminating lamp must not be connected with any heater, such as a foot
warmer and others, in parallel. Otherwise, the load capacity will be exceeded.
It may cause transformer winding burned out.
3) Rotary direction
I
t is possible to change the rotary direction of the motor by removing the rubber cap from the
bottom left side of the front cover on the control box, and push the internal direction selector switch.
The built-in lamp in the internal switch is off when the motor is rotating counterclockwise as facing
to the motor pulley, and on when rotating clockwise. The rotary direction has been set t
counterclockwise as facing to the motor pulley, matching with the machine prior to shipping.
2． Connection of control box
The control box should be connected
as shown to the right.
Note: (1) Be sure to turn the power switch
off for safety before connecting
or disconnecting the connectors.
