Power Fail (Output)
If AC input fails (below 20 V DC), level decreases to -7 V DC.
If AC input ok, level is at +7 V DC.
Battery Low (Output)
If the battery is low, level decreases to -7 V DC.
If the battery is ok, level is at +7 V DC.
Shutdown (Input)
Signal to switch off the PSU in UPS mode.
The level has to be ≥+7 V DC and has to be connected ≥60 msec. The UPS switches off
after app. 15 sec.
The output voltage corresponds to the connected input
voltage minus app. 0.45 V DC.
The (5-pole) pin-and-socket connector is included in the
delivery of the DC UPS UPSI-2401.
5 Installation and Start up
Connections
