Emerson 480V ユーザーズマニュアル

The MultiPort 4 card provides four sets of voltage-free contact closures for remote monitoring of 

alarm conditions UPS operation On Battery and Low Battery condition. A typical application is to 

allow a maximum of four computer systems to simultaneously monitor the status (e.g., utility power 

failure-low battery) of a single UPS.
This card is supported in any of the three Liebert IntelliSlot bays on the Liebert NX.
