•
To ensure that the inverter can be safely disconnected from the power grid when an
exception occurs, connect an AC switch to the AC side of the inverter. Select an appropriate
AC switch in accordance with local industry standards and regulations.
•
Connect cables in accordance with the local installation laws and regulations.
•
Before connecting cables, ensure that the DC switch of the solar inverter and all the switches
connected to it are set to OFF. Otherwise, the high voltage produced by the solar inverter
may cause electric shocks.

Prepare cables based on site requirements.
• Do not connect loads between the inverter and the AC switch that directly connects to the
inverter. Otherwise, the switch may trip by mistake.
• If an AC switch is used with specifications beyond local standards, regulations, or Huawei's
recommendations, the switch may fail to turn off in a timely manner in case of exceptions,
causing serious faults.
Each inverter must be equipped with an AC output switch. Multiple inverters cannot connect
to the same AC output switch.
