EPO Port Connection
2
This optional feature is only for those applications which require connection to a
facility's Emergency Power Off (EPO) circuit. When the power module is con-
nected to this circuit, it enables emergency shutdown of the output. Using the
2a
included cable
, connect the power module's EPO port to a user-supplied remote
switch. The pin assignments for the EPO port are shown in diagram
there is a short between pins 2 and 3, 2 and 5, 4 and 5, or 3 and 4, the UPS system
will power off.
Internal SNMP/WEB Card Insertion
3
Remove the small cover panel from the accessory slot to use optional accessories
to remotely monitor and control your UPS. Contact Tripp Lite Customer Support
at (773) 869-1234 for more information, including a list of available SNMP, net-
work management and connectivity products.
Note: RS-232 serial communications are unavailable for PowerAlert Software monitoring while the SNMP/WEB Card is installed in the UPS system's accessory
slot. Removing the SNMP/WEB Card from the accessory slot will restore the availability of RS-232 serial communications for PowerAlert Software monitoring.
Manual Bypass Operation
The UPS system includes a self-contained power/battery module along with an independent, detachable PDU with a bypass switch. This
switch allows qualified service personnel to remove the detachable PDU from the power/battery module for routine maintenance without
disrupting power to connected loads. While this switch is set to "BYPASS", connected equipment will receive unfiltered AC utility power,
but the equipment will not receive battery power in the event of a blackout.
Note: If desired, an optional hardwire detachable PDU is also available separately from Tripp Lite. Contact Tripp Lite for details.
(Optional: During a hot-swap, the PDU can be housed in the back of the rack configuration using supplied PDU hanger brackets and hard-
ware. See STEP 1 on page 11 for mounting instructions.)
WARNING! For qualified service personnel only. Failure to follow the bypass procedure completely will not adequately power down
the UPS power/battery module, resulting in the continued risk of death or injury from potential contact with high voltage. The
UPS's power/battery module and detachable PDU are extremely heavy. This procedure requires several people to perform.
