NOTE
• When the wiring length from a unit to the node point is less than 10 m, a balance reactor (FR-POL) is required.
 Selecting the breaker / magnetic contactor
Check the model name of the inverter and the converter unit you purchased. Appropriate peripheral devices must be selected
according to the capacity.
Refer to the following table to prepare appropriate peripheral devices.
• One circuit breaker and one magnetic contactor in total in a system
