## Panel cut-out 

## Panel mounting 

1) Remove the mounting clips from the unit. 

- 2) Insert the unit from the front of the panel. 

- 3) Attach the mounting clips at the both side of the case and secure in place with the screws. 

• Applicable panel thickness: 1 to 5mm 

92 ±0.5 When mounting several units adjacent to each ~~——~~ other, keep at least 130mm of space on all sides measured from the center of the unit.

## Features 

## **Feature 1** 

- Large-screen LCD with backlight clearly displays values in four lines 

- High accuracy! Instantaneous active power: 1%, class 1 (IEC62053-21) Display updating time: 0.1s 

## **Feature 4** 

- Capable of displaying currents as low as 1mA 

- This allows standby power consumption to be monitored, which helps save energy

## **Feature 2** 

- The total and individual power values of each phase are displayed on one screen, enabling you to check the phase balance at a glance. The data is useful for power quality checks and power factor improvements. 

## **Feature 5** 

   - Regenerative power can also be measured by one KW9M Eco-POWER METER. Bidirectional integrated electric power of each circuit can be measured. 

- Capable of displaying voltages, currents, electric power (active, reactive, apparent) and power factor
