4. Be careful when using metal tools in vicinity of batteries. Dropping a metal tool onto a
battery might cause a shorted battery and an explosion.
5. Remove personal metal items such as rings, bracelets, necklaces, and watches when
working with a battery. A battery can produce a short-circuit current high enough to weld
a ring or the like to metal, causing severe burns.

The serial communication port
This inverter is equipped with an RS485 serial communications port for future use. This port can be
used to communicate with an optional remote control panel or for connection to a TBS-Link
compatible data network. 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 (166 feet).
DO NOT CONNECT THE INVERTER'S SERIAL COMMUNICATION PORT TO
AN ETHERNET NETWORK OR TO ANY OTHER NON TBS-LINK
COMPATIBLE NETWORKS.
WARNING
2.7
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, are drawing large inrush
currents during startup. In these kind of situations, it is possible that the startup current is
exceeding the overcurrent trip level of the inverter. In this case the output voltage will shortly
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
disconnect this 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
reducing.
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 shortly 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.
