4.9 Installing the Surge Protection Devices
SPD (optional)
Fig. 24: Surge protection device adapters
▷ Insert the optional surge protection module (SPD)
into the appropriate adapter rail until it clicks.
Make sure that AC and DC SPD are not inter
-
changed and plugged in correctly. This can be seen
from the setting pin on the backside of the surge
protection module.
4.10 Communication Connections
The
REFUsol 100K
is equipped with RS485 and Ether -
net communication ports for an easy integration into
monitoring and control systems.
The RS485 and Ethernet (100BaseT) is mapped on
the same RJ45 connectors (RS485/LAN 1...2), located
at the PowerUnit’s back side.
The inverters can be connected in daisy chain, using
a single Ethernet cable CAT 5e (or better) between
each inverter.
For redundancy purposes, you can also connect the
last with the first inverter as a ring topology. Alterna -
tively, they can all be connected separately to a switch.
Inverters in night mode or with non-functional con -
trol boards are automatically by-passed to always
ensure a working bus system.
