4.4 Connecting the Battery to the Inverter
Danger to life due to burns caused by electric arcs through short-circuit currents
Short-circuit currents in the battery can cause heat build-up and electric arcs . Heat build-up and electric arcs
may result in lethal injuries due to burns .
•
Disconnect the battery from all voltages sources prior to performing any work on the battery .
•
Disconnect the inverter from all voltages sources prior to performing any work on the inverter .
DANGER
•
DO NOT short-circuit the battery terminals . First, complete the main negative terminal connection between
battery and inverter, and then complete the main positive terminal connection between battery and inverter .
•
Observe battery safety information provided in the Safety and Installation Instructions .
