-
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 fitted on the dc-link side ( C and D terminals) of each inverters (see
chapter 10.1.2
).
(*) Do not connect if external braking units BUy.. is used.
(*) Pas raccorder si l’unité de freinage extérieure BUy... est utilisée
