Use only control cables supplied to interconnect inverters. Do not use substitute
cables (eg computer cables) - electrical noise problems may occur

Control Interconnection for Parallel Units
A direct earth bonding wire of not less than 6mm
2
is required between adjacent inverter
modules for functional purposes.
In addition, one (only one!) earth connection should be made from the master inverter module to
the switchboard earth link. Do not use the inverter module earth connections to earth other
components or cable screens etc. The reason for this requirement is to avoid possible earth
currents from other sources flowing in the earth bonding wire between inverter modules. High
frequency currents in the bonding connections may induce sufficient voltage between inverter
modules to cause improper operation.
