When a signal is received, the contacts for connectors X3 of the
master and expansion boards are closed between the two contact
points with the lowest numbers (normally open "NO").
When a signal is received, the contact for connector X4 of the
master board is open between the two contact points with the low-
est numbers (normally closed "NC").
The control signal is active when the input for connector X5 of the
master board and connector X4 of the expansion board is bridged
(normally open "NO").

7.10 Input Current Measurement System (Optional)
When installing the equipment with an input current measurement
system A41:1-5, it is important that the nominal values of all eight
input currents are as equal as possible. This means the PV mod-
ules (zones) must be connected to the individual GCBs in the
same way, e.g.:
The same module types
•
The same series connection or •
The same parallel connection
The input current measurement system is an intelligent CAN as-
sembly with multiple interfaces.
