Communications Interface Port
The S4K5U UPS has a standard DB-9 serial port female connector located on the rear of the UPS
unit. Several signals are provided on this port and are assigned as follows:

Whether the UPS turns back ON when power is restored depends on the auto-restart setting: enabled
or disabled.
If the auto-restart is disabled, the UPS will not restart after performing the 2-minute shutdown
delay.
* Maximum voltage and current on pins 1, 7, 8 and 9 are 60VDC and 10.0 mA
