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
correspondingly connected to the L1, L2 and L3 terminals of power input on the
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, and the model of 3kVA and 5kVA power supply can support single
phase AC power input. The detailed specifications refer to Technical
Specifications The voltage level range is 190V-528V and frequency range is
45Hz65Hz. (Note: here is the line voltage, such as L1 and L2)
Please pay attention to the AC input voltage level:
NOTE
When the AC input voltage of 5kVA and 12kVA or above are in the range
of 190V-240V, the power setting value is derated to 60%, and when the
output exceeds the present rating, the instrument enters AC Input
Overcurrent protection and the output is turned off. If a full power output
is required, the AC input level Voltage must be greater than 240V.
The instrument which rated power less than 6kVA consumes different current on
the three phases. Take the 3kVA instrument for example, the rated AC current
of each phase for the single unit is L1/L2:18A, L3:0A, and can support single
phase AC input. different model of rated AC current is different, the detailed
specification refer to the technical specification.
Connecting the Power Cord
z When connecting the instrument which rated power is 3kVA or 5kVA
please take care for balanced current distribution on three phases. For single
unit, it supports single phase input, and it requires single phase or three phases
of AC distribution box (the rated AC current on L3 is 0, so, it can be connected
or not). In case multiple units are connected to the same main AC distribution
box. It is recommended to follow the suggestion connection diagram as below.
