Input Breaker: Protect your electrical circuit from overcurrent draw
from the UPS load. If this breaker trips, remove some of the load,
then reset it by pressing the breaker in.
External Battery Connector (Select Models Only): Use to connect
Tripp Lite external battery packs for additional runtime. The specifi-
cations section of this manual lists the Tripp Lite external battery
packs that are compatible with your model. Refer to instructions
available with the battery pack for complete connection information
and safety warnings.
AC Input Receptacle: Connect one end of the detachable line cord
into this receptacle and the other end into your wall outlet.
"SITE WIRING FAULT" LED: This red LED will be lit if the UPS
detects a problem with the wiring of the AC outlet you connect it to.
If this occurs, have the outlet inspected by a qualified electrician.
Note that while the UPS will detect many common wiring faults,
including a missing ground, reversed polarity and overloaded neutral
circuits, it cannot detect every conceivable wiring problem.
