Operating status 

 

The busbar voltage and current values are displayed with three 
decimals before and one decimal after the decimal point. The display 
accuracy corresponds to class 1 with respect to the rated output 
value of the unit. 

Remote signalling is carried out by means of potential-free contacts 
via a Combicon connector on the front of the unit. 

Assignment of the signal terminals: 
SBS fault:  

In the event of a signal, X4.2 – X4.3 close, no fault: X4.2 – X4.1 
•  When the SBS is disconnected from the power supply (no mains / 

INV supply), a fault is signalled! 

INV operation: 

In the event of a signal, X4.4 – X4.5 close 

The remote signals are designed for safe isolation. The minimum load 
should not be below 12 V and 0.1 A. 

Two operating modes can be selected using the DIL switches 
(see chapter 4.11). 

 

The switchover from INV to SBS is always carried out without 
interruption. If the INV and SBS circuit are not synchronous, the SBS 
blocks. If the INV is switched off due to asynchronism or if it fails, the 
load is not supplied by the SBS. 

This operating mode is set ex works and is recommended.

NOTE:  
If the mains are poor or the SBS circuit is supplied by a diesel 
generator for example, the SBS can be temporarily blocked due to 
frequency deviations.
