* Normally closed (NC) /open (NO) connection state when the Relay Interface Card is not powered.
** The shutdown pin (15) needs minimum of 5 seconds high level signal (connection to +12VDC) to perform the UPS shutdown.
NOTICE: The relay contacts must not be galvanically connected to any mains connected circuits. Do not use +12VCD (Pin13) of the Relay Interface Card for any power supply purposes for external devices. Reinforced insulation to the mains is required for equipment and cables connected to these connections.
The relay contacts are rated for maximum 1A/30VAC or 200mA/60VDC. All relay outputs are galvanically isolated from the other circuits of the UPS (IEC 950, EN 50091-1).

Shut down function

The Relay Interface Card shut down functionality depends on the jumper (JP1, JP2 & JP3) selected on the board and on the UPS mode (Normal or On Battery). The functions are described in table 2.
