4. Electrical Connection
1)
Fix the motor, the customer has, to the base, if the customer purchased the pump without the motor.
2)
Remove the V-belt, when connecting the wires.
3) Switch in and watch the direction of rotation of the motor pulley. An arrow mark (like this: ⇒ ) is
put on the model name plate to indicate the right direction of rotation. If the pump does not rotate
in the right direction, interchange any two of the three-phase leads.

4) Be sure to install a safety circuit such as a motor breaker or fuse in front of the motor, and an
electromagnetic switch (with thermal relay) for remote starting. Use the safety circuit capacity
shown in Table 4.
Attention: Be sure to use the motor breaker. Since a current 5 to 10 times the rated current flows
when the motor starts, a general-purpose breaker may trip at the motor starting current.
