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 current
