1.3 Electrical Connection Safety
Before electrical connections, please make sure that the inverter is not damaged,
otherwise it may cause danger!
Before electrical connections, please make sure that the inverter switch and all
switches connected to the inverter are set to "OFF", otherwise electric shock may
occur!
The PV string will generate lethal high voltage when exposed to sunlight.
• Operators must wear proper personal protective equipment during electrical
connections.
• Must ensure that cables are voltage-free with a measuring instrument before
touching DC cables.
• Respect all safety instructions listed in relevant documents about PV strings.
Danger to life due to a high voltage inside the inverter!
• Be sure to use special insulation tools during cable connections.
• Note and observe the warning labels on the product, and perform operations
strictly following the safety instructions.
• Respect all safety instructions listed in this manual and other pertinent
documents.
If the battery is short-circuited, the instantaneous current will be excessively high
and a large amount of energy will be released, which may cause fire and personal
injury.
Disconnect the battery from all voltage sources prior to performing any work on
the battery.
Lethal voltages are present at the battery terminals and cables connecting to the
inverter. Severe injuries or death may occur if the cables and terminals in the inver-
ter are touched.
Observe all safety information provided by the battery manufacturer.
