The figures below show measurement locations for voltage, current, and power measure-

ments listed in the table on the previous page. The voltage to be measured is the funda-

mental wave effective voltage. The power to be measured is the total effective power.

Conduct the insulation resistance test by short circuiting the terminals as shown below.

CAUTION: Never test the withstand voltage (HIPOT) on the inverter. The inverter has a

surge protector between the main circuit terminals above and the chassis ground.
