4.2 System Integration Interface

4.2.1 Introduction

Single Mains Input

The system Integration Interface (SII) is the control link between the UPS and the

system main switches as shown in the above diagram. The purpose is to ensure

correct operation of the switches without loosing the system output power.

Position information from auxiliary contacts on the main switches are the inputs for

the SII-board and the outputs are the lamp signals giving “the green light” for

operating the specific switches.

Besides above the SII-board also have input facilities for emergency shut down and

temperature compensation of the charge voltage for systems with external battery.

“Battery operation” and “Common fault” are the two main status relay signals also

coming from the SII-board.

NOTE:

Use of the same designations

in your diagrams make informa-

tion exchange much easier.
