Any Mode Shutdown

The purpose of Any Mode Shutdown is to shut down the UPS output by turning Off the rectifier, inverter
and static switch so that there is no power to the loads.
Any Mode Shutdown can be operated locally or remotely:
• Local Any Mode Shutdown can be performed by shorting pins1 and 2.
• Remote Any Mode Shutdown can be performed using a switch mounted at a remote location and
connected to pins1 and 2.
NOTE
Remote Power Off will be performed either by NO or NC contact of Any Mode Shutdown,
depending on the settings in the configuration program.
A current-limited source for this optocoupler (+12 VDC, 50 mA) will be available from the UPS.
The connection to the UPS for remote connection will be via terminal block connector.
Any Mode Shutdown wiring must conform to all national, regional and local wiring regulations.
