Description / information
Sunny Island: connection BatTmp
You only have to connect a battery temperature sensor if lead-acid
batteries are used.
Mount the battery temperature sensor in the middle of the battery-
storage system, in the upper third of the battery cell.
Use the ferrite included in the delivery.
The control cable must be connected if a Grid-Connect-Box is in-
stalled.
Sunny Island: connection Relay1 terminals C and NC
Multicluster-Box: connection X112 terminals 1 and 2
Conductor cross-section: from 1.5 mm
Sunny Island: connection Relay2 terminals C and NO
Multicluster-Box: connection X113 terminals 1 and 2
Conductor cross-section: from 1.5 mm
Sunny Island: connections DigIn+ und BatVtgOut+
Multicluster-Box: connection X113 terminals 3 and 4
Inside the Sunny Island, connect terminals DigIn- and BatVtgOut-.
Conductor cross-section: from 1.5 mm
The complete DC voltage range is mapped at the terminal BatVt-
gOut. The connection BatVtgOut is current-limited and protected
against short circuits. Use the supplied ferrite for BatVtgOut.
Terminal ComETH
At SI-SYSCAN.BGx terminal SysCanIn
Master of the extension cluster: at SI-SYSCAN.BGx
Terminal SysCanOut
The communication bus must be equipped with a terminator on both
ends.
At SI-SYSCAN.BGx terminal SysCanOut
The communication bus must be equipped with a terminator on both
ends.
Sunny Island: terminal ComSyncOut
The communication bus connects the master with the slaves in each
cluster and additionally with the Multicluster-Box in the main cluster.
The communication bus must be equipped with a terminator on both
ends.
