5.7.1 Introduction
The inverter offers the following options for communication with
other devices (e.g. PC, smartphone, data logger):
●
RS485 (communication card with RS485 connections,
digital inputs, dry contacts, external power-off and 12 V
DC
power supply)
●
Sub-1G antenna (included in scope of delivery)
●
Wi-Fi module (optional accessory)
5.7.2 Components of the communication card
The connections for RS485, the digital inputs, the
dry contacts and the external power-off (EPO) are
all on the communication card. This means that
the installation work can be combined.
