4.2 AC Connection
Select a suitable circuit breaker and consider the factors influencing the ampacity of the cable: type of
cable used, ambient temperature around the cable, type of cable routing, bundling of cables. Other
influences on dimensioning: loop impedance, mutual heating of circuit breakers, ambient temperature
at the circuit breaker, selectivity, type of connected device. If these factors are ignored, it increases
the danger of the circuit breaker tripping under normal operating conditions.

4.4 BAT Power Connection
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.
•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 Installation&Operation&Maintenance Manual.
