Safety Instructions
For personal and device safety during electrical connection, observe the safety instructions
described in this manual, especially in this chapter, and respect the national/local standards
and regulations.
7.1.1
General Safety Rules
High voltage! Electrical shock!
Do not touch the live component!
Ensure that both the AC and DC side are voltage-free before starting
installation.
Never put inflammable materials in the vicinity of the inverter.
Do not use an ordinary multimeter to measure the DC voltage. A multimeter with
voltage withstanding of at least 1,500V is recommended. Otherwise, serious
damage may follow.
All electrical connections must comply with national/local standards.
Connect the inverter to the gird only after an approval is received from the local
power supply company and technical persons have finished the installation.
Only professional electricians and qualified personnel can perform electrical
connections.
Perform cable connections strictly according to the wiring identifications inside
the device.
7.1.2
Five safety Rules
During the whole electrical connection process or other operations on the inverter, respect
the following five safety rules:
Disconnect all external connections and internal power supply connections to the
inverter.
Ensure that the inverter cannot be powered on accidentally.
Ensure that the interior of the inverter is completely voltage-free by using a multimeter.
Perform necessary grounding and short circuit connection.
Use the insulation clothing to cover and insulate the possible live components adjacent
to the operation area.
