J3
DB-9
PIN DESCRIPTION
1 Low Battery ( When UPS reaches low battery, contact activates)
(J1, 1-2 short = N.O) (J1, 2-3 short = N.C)
2 JP2 shorted = Low Battery common & all other shorted JP commons
JP2 open = common for low battery only
3 Utility Loss N.O. ( At loss of utility voltage, contact activates)
4 Utility Loss N.C. ( At loss of utility voltage, contact activates)
5 JP1 shorted = Utility Loss common & all other shorted JP commons
JP1 open = Utility Loss common only
6 Remote Shutdown common
7 Remote Shutdown
(J2, 1-2 short = outside power) (J2, 2-3 short = inside power)
1-2 shorted.
Applying an external 12V signal across the DB-9, pins six
and seven, while the UPS is on battery, will turn the UPS off.
2-3 shorted
. Applying a short directly across the DB-9, pins six and
seven, while the UPS is on battery, will turn the UPS off.
8 Alarm (Upon a UPS fault or failure the contact activates)
(J3, 1-2 short = N.O.) (J3, 2-3 short = N.C.)
9 JP3 shorted = Alarm common & all other shorted JP commons
JP3 open = Alarm common only
