Optionally, slow blow fuses can be used at the input. They must be sized for 1.2 x the inverter rated input
current. In this case, the installation is protected against short-circuit, but not the inverter input rectifier. This
may result in major damage to the inverter in the event of an internal component failure.
Table 3.2 - Recommended wire gauge and fuses for standard models - use only copper wire [75 ºC (167 °F)]
