Check the panel and the chassis for obvious impact such as scratches and dents on the surface caused by the transport or handling. Confirm that the dials can turn smoothly. If an abnormality is found, contact both Matsusada Precision and the delivery company. Installation 1-7-1 Installation conditions This product is a high voltage supply.
Confirm the AC input voltage displayed on the rear panel to correctly input the voltage. Using the unit with an incorrect voltage could cause damage to it. 1-7-3 GROUND connection Be sure to ground the GND terminal of the power supply at a single point for safety reason.
