and input power and terminals. The capacity of the inverter should be 1.5-2 times of the rated current.
Due to the inherent operating principle and construction of circuit breakers,
independent of the manufacturer, hot ionized gases may escape from the breaker
enclosure in case of a short-circuit. To ensure safe use, special attention must be
paid to the installation and placement of the breakers. Follow the manufacturer’s
instructions.
It is necessary to install the electromagnetic contactor in the input side to control the switching on and off
safety of the main circuit. It can switch off the input power supply when system faults.
