5.7.1 Introduction
The inverter o󰀨ers 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-o󰀨 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-o󰀨 (EPO) are
all on the communication card. This means that
the installation work can be combined.
