you must also ensure proper use of the serial port when connecting the
UPS to your network or monitoring equipment.

50 mA and a maximumof +40 Vdc. Do not exceed these ratingsor applyany
negative voltageor AC voltageto thesecontacts;otherwise, damage mayoccur to
yourUPS.
Use only the pins specified for your communications configuration. The
use of any additional pins for any of the following interfaces can cause
interference with system communications.
Even though your network uses the specified signal lines, the pins
assigned to these signals at the network end of the cable may vary with
those of the UPS serial port. The connector body and style may vary as
well.
