Connection of the PhaseBalancer

Lack of function due to missing setting!
Â
Adjust Phase Balancer settings within 4 hours after
startup of inverter (see 6.1 Change settings).
Setting at a later time is not longer possible.
Caution
To use the PhaseBalancer, a connection of the power inverters via the
RS 232 interface is necessary. The connection takes place using the
connection cable that was included in the delivery of the
PhaseBalancer.
The length of the connection cable is 2 m.
 During installation, select the distance between the inverters of a
group in such a way the the length of the balancer cable is
sufficient.
