The cable must be connected according to the following diagrams. The
communications cable must be connected to the inverter's "IN" terminal. In the
event of several inverters, their communications cable must be connected from
the first inverter's "OUT" terminal to the next inverter's "IN" terminal, as shown in
Figure 2 , and successively until reaching the last inverter, whose bus terminal
resistance ("Match Resistance") must be set as activated.

The communications cable between inverters is a pin-to- pin cable with RJ45
connectors at both ends. This type of cable can be purchased at any computer
