Factor analysisElimination method
1. If the wiring mode is incorrect,
please connect based on the
correct wiring mode (see the
wiring diagram).
2. If the supplied voltage is
abnormal, please supply the
voltage on the instrument
specification.
1. If any problems for the
communication cable, please
change the cable.
2. Set the address, baud rate,
data bit and parity bit of the
instrument to be the same as the
inverterthrough buttons and so
as the "parameter setting".
1. For wrong wiring, please
connect based on the correct
wiring mode (see the wiring
diagram).
2. If a negative value is
displayed, change the cable
connection mode of the current
transformer to ensure that the
high and low ends are
connected properly.
Fault phenomenon
No display after the
instrument being
powered on
1. Incorrect wiring mode.
2. Abnormal voltage supplied for
the instrument.
Abnormal RS485
communication
1. The RS485 communication
cable is disconnected, short
circuit or reversely connected.
2. The address, baud rate, data
bit and parity bit of the
instrument is not in accordance
with the inverter.
Power metering
inaccuracy
1. Wrong wiring, please check
whether the corresponding
phase sequence of voltage and
current is correct.
2. Check whether the high & low
end of current transformer inlet is
reversely connected. Please
observe the power, to be
abnormal if any negative values.

Verifying the Installation
that all mounting brackets are securely installed and all screws are tightened.
that all cables are reliably connected with correct polarity and no short circuit.
