Measurement Methods of I/O Voltage, Current, and Electric Power
Below are general measurement devices for I/O voltage, current, and electric power.
Measure effective values of fundamental wave for voltage, and all effective values for electric
power.

*1. The life of the capacitor depends on ambient temperatures. Refer to the product life curve in Appendix-2.
When the capacitor stops operating at the end of the product's life, the Inverter must be replaced.
*2. Clean the Inverter periodically. Accumulated dust in or on the cooling fan or heat sink can cause the Inverter
to overheat.
