4.8.11 Inverter RS485 communication connections
Read all of these instructions, cautions, and warnings for the Delta
E series inverter and associated PV array documentation.
Lisez toutes les instructions, rubriques Prudence et Avertissement
de l’onduleur Delta E series , ainsi que la documentation sur le
panneau photovoltaïque associé.
Interface connection RS485 (EIA485)
The Delta E series inverters oer an EIA RS485 communication interface which can address up
to 31 daisy chained inverters. For optimal performance, all unused interface connections must
always be terminated by placing the termination jumper in the “on” position.
WARNING!
AVERTISSEMENT!
Clearly distinguish between grid and backup load connections. If
there are multiple inverters in the installation, each inverter should
be connected to a separate backed-up loads panel. Do not share
backup output between inverters.
Distinguer clairement entre les connexions de réseau et celles de
la charge de réserve. Si l’installation contient plusieurs onduleurs,
chaque onduleur doit être connecté à un panneau de charge de
réserve distinct. Ne pas partager la sortie de charge de réserve
entre les onduleurs.
NOTICE!
AVIS!
