Wiring example
• In order to make the ON-OFF operation, install the switch between the DC
power supply and the pump. Installing it between the DC power supply and
the AC power supply, the pump may not run.
• After wiring work, check that the system is free from the inductive noise at
start-up.
• Noise accompanies the high-speed switching of the drive circuit. Check it
does not affect peripheral devices.
• If a power source is shared with the inductive load such as solenoid and
relay, take protective measures against surge.
