6.1 Typical connection modes
This chapter describes ten kinds of typical connection modes, from which the customer can
select according to his own needs. When a connection macro is selected via the operator panel
(for details, please refer to " Operation mode ② - Connection macro selection") after the wiring
work, relevant parameter settings will be done automatically, which greatly helps simplify the
work of quick commissioning
WARNING
Direct contact between copper earthing conductor and aluminium PE terminal will lead to
significant corrosion due to electrochemical action! Make sure that copper earthing conductor
is corrosion resistant or properly plated.
The earth-leakage current exceeding 3.5 mA may occur during normal operation of the
inverter. A permanently fixed ground connection must be provided.
CAUTION
The inverter digital input terminals, analog input/output terminals and the communication port
between the inverter body unit and the operator panel should be double-insulated from live
parts and meet the requirements for SELV (Safety Extra Low Voltage) in EN61800-5-1, and
those terminals shall be connected to other SELV circuits.
The inverter output terminals (relay output, max. 250 V) are at a dangerously high voltage
when Non-SELV control voltage is applied. Use only approved double insulated cable for
supply connection with nominal cross-section area of at least 0.75 mm
