Basic Connection Diagram of HLP-C100 series inverter:
Precautions for the main circuit wiring:
●
While wiring the sizes and speci
fi
cations of wires should be selected and
the wiring should be executed according to the electrical engineering
regulations to ensure the safety.
●
It is better to use shielded wire or wire conduit for power cord and
ground the shielded layer or two ends of wire conduit.
●
Be sure to install a circuit Breaker between the power supply and the
input terminals (R.S.T). (If using RCD, please choose B type)
●
Phase-shif ting capacitors, LC, RC noise f ilters etc, can never be
connected to the output terminals of the inverter.
●
Please lower the inverter switching f requency when there is a longer
distance between the inverter and the motor.
●
Drive earth leakage current is greater more than 3.5 mA. According
to the requirments of IEC 61800-5-1 , must use the following ways to
enhance the protection of ground: minimum 10mm
2
cross sectional area
of copper, or additional PE line, its cross sectional area and the main
power cable should be the same, must be separate grounded.
●
Make sure reliable ground of the inverter in accordance with IEC 61800-
5-1.
●
Please refer to 9.2 for the use of RFI SWITCH.
