- The inverters used have to be all the same size.
- The mains power supply has to be simultaneous for all inverters, i.e. a single switch /line contactor has to be used.
- Such connection is suitable for a maximum of 6 inverters.
- If necessary dissipate braking energy; a single internal braking unit (with external resistor) has to be used or one (or several) external braking unit.
- Fast fuses (F12...F62) have to be tted on the dc-link side ( C and D terminals) of each inverters (see chapter 5.1.2).
(*) Do not connect if external braking units BUy.. is used.
(*) Pas raccorder si l’unité de freinage extérieure BUy... est utilisée
