Inspection and Installation

The yellow-green wire is grounding wire, which is connected to the PE terminal

of power input on the rear panel; the others are live wires, which are corre-

spondingly connected to the L1, L2 and L3 terminals of power input on the rear

panel of the instrument.

AC Power Input Level

The input of this series is a three-phase AC power (three-phase four-wire). The

voltage level and frequency are as follows. (Note: here is the line voltage, such

as L1 and L2)

• Voltage 1: 198V to 264V (Derating 50%), frequency: 47Hz to 63Hz

• Voltage 2: 342V to 528V, frequency: 47Hz to 63Hz

• When the AC input voltage is in the range of Voltage 1, the power

setting value is derated by 50%, and when the output exceeds the

present rating, the instrument enters AC Input Overcurrent protec-

tion and the output is turned off. If a full power output is required,

the AC input level Voltage 2 must be selected.

• Models without emergency stop module (i.e. AC contactor not in-

cluded), other AC input voltage ranges are required for

customization.

• Models without emergency stop module and assembled to the cabi-

net, with AC input voltage in the range of 198~264V, need to be cus-

tomized while derating by 50%.

• Models with emergency stop module (including AC contactor) only

support 380VAC±10% for standard AC input voltage, 480VAC±10%

voltage is required for customization.

The instrument which rated power less than 15kW consumes different current

on the three phases. Take the 5kW instrument for example, the rated AC
