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.
(1) In case of three-phase electrical power system, the "U" phase should be connected to the red lead,
the "V" phase to the white lead, and the "W" phase to the black lead. The motor rotary direction
depends, however, upon the setting of the internal switch in the control box as described in
Paragraph [T|-3.
CAUTION: The green wire must be connected to the ground terminal in order to ground the
motor properly.
(2) The appropriate power fuse capacity is as follows.
Power supply 200V
100V
240V: 10A
120 V: 15A
Lamp Leads
(1) When installing the illuminating lamp (GV,
15 to 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 connect
ing the lamp.

(2) When the illuminating lamp is not used, the end of the lamp leads must be insulated as 0 or (D as
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.
Rotary Direction
It 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 to
counterclockwise as facing to the motor pulley, matching with the machine prior to shipping.
