rear panel of the instrument.
AC Power Input Level
The AC input of this series is a three-phase AC power (three-phase four-wire)
by default, the detailed specifications refer to Technical Specifications.
Please pay attention to the AC input voltage level.
NOTE
Connecting the Power Cord
The AC input is three phase and balanced, connecting the power cord as below.
Operation procedures:
1. Confirm that the switch of the AC power distribution box is off.
2. Confirm that the power switch is in the OFF position and verify that there is

When the instrument input three-phase line voltage is ( 198 to 264 ) V, 50% of the rated
power is output at 40℃ ring temperature and 40% of the rated power is output at 50℃
ring temperature. When the output exceeds the present rating, the instrument enters AC
