Table 10. Interface COM A

Pin Number

Condition

 

 

SGN at pin 5

This connection point serves as a reference for all signals.

 

 

RXD at pin 2 and TXD at pin 3

In conforms standard RS232 configuration.

 

 

 

This input (pin 2: High signal +5V...+12V, > 1 second, pin 5: 0V)

INV SHUTDOWN at pin 2

enables the control processor to switch off the UPS in the event of a

mains failure. After the mains has been reestablished, the UPS

 

 

starts again independent of this signal status.

 

 

BATTERY LOW at pin 1

This output goes low, when the battery can supply current for

approximately 3 more minutes at nominal load.

 

 

 

 

Pin 9 goes low and pin 6 goes high for mains voltage failure at the

AC FAIL at pin 9 and

UPS input for a minimum of 10 seconds or when the mains voltage

AC FAIL at pin 6

moves beyond the tolerance band. The signal is reset 850 ms after

 

the mains have been reestablished.

 

 

BYPASS ACTIVE at pin 7

This signal goes low after switching over to bypass, blocking the

inverter and the energy being supplied by the mains

 

 

 

 

This output is low, when one of the alarms “BATTERY LOW”, “AC

SUM ALARM at pin 8

FAIL” or “BYPASS ACTIVE” is given.

 

 

15.2 Optional Interface COM B

The optional interface COM can be equipped with various interface cards. The designation beside the plug then depends on the type of interface card.

In the following the function of the interface signals for version COM B is described. The optional interface COM B provides potential-free signalling contacts and a shutdown input and an insulated auxiliary supply.
