The serial communication port

The Phoenix 12/850 inverter is equipped with an RS485 serial communications port for future use.
The communication port wiring is designed to work with a standard RJ45 terminated Ethernet
compatible patch cable. Maximum recommended cable length is approx. 50 meters.
DO NOT CONNECT THE INVERTER'S SERIAL COMMUNICATION PORT TO
AN ETHERNET NETWORK OR TO ANY OTHER NON COMPATIBLE
NETWORKS.
THIS COMMUNICATION PORT IS FOR FUTURE OPTIONS.

Connecting the load

Before you connect your appliance(s) to the inverter output, always check it's maximum power
consumption. Do not connect appliances to the inverter needing more than the nominal power
rating of the inverter continuously. Some appliances like motors or pumps, may draw high inrush
currents during startup. In this kind of situations, it is possible that the startup current exceedes
the overcurrent trip level of the inverter. In this case the output voltage will quickly decrease to limit
the output current of the inverter. If this overcurrent trip level is continuously exceeded, the inverter
will shut down and restart within 18 seconds. In this case it is advisable to
appliance from the inverter, since it requires to much power to be driven by this inverter. Note that
at higher ambient temperature levels, the overload capacity of the inverter is reduced.
Besides indicating the type of error, the red LED on the inverter also functions as an overload
indicator. When heavy loads are switched on, this LED will quickly be activated due to the inrush
current of the load. If the ERROR/OVERLOAD LED stays on for 6 seconds, the inverter will shut
down and jumps into the overload error mode (see chapter 3.1)
NEVER CONNECT THE INVERTER'S OUTPUT TO THE AC DISTRIBUTION
GRID, LIKE YOUR HOUSEHOLD AC WALL OUTLET. IT WILL DAMAGE THE
INVERTER.
CAUTION
WHEN CONNECTING MORE THAN ONE APPLIANCE TO THE INVERTER,
IN COMBINATION WITH A COMPUTER, NOTE THAT IF ONE OF THE
APPLIANCES STARTS UP, IT CAN CAUSE YOUR COMPUTER TO REBOOT
DUE TO A SUDDEN VOLTAGE DROP.
