Units with DC Power Supply
Note: 1. Be sure to connect the COM terminal before turning ON the power supply. If the COM terminal is disconnected, or if the wiring is changed
after turning ON the power supply, a malfunction may occur.
2. Apply the power supply voltage through a relay or switch in such a way that the voltage reaches the rated value within 4 s. If the voltage
is applied gradually, the power may not be reset or unstable output operations may result.
