Optional Connection (continued)
EPO Port Connection
2
This optional feature is only for those applications that require connection to a facility's
Emergency Power Off (EPO) circuit. When the UPS is connected to this circuit, it enables
emergency shutdown of the UPS's inverter and inhibits transfer to internal bypass. Using the
cable provided, connect the EPO port of your UPS (see
or normally open switch according to the circuit diagram (see
Note:
1. If using a cable other than what is supplied, the cable should not exceed 350 feet or
have a resistance of greater than 10 ohms.
2. If a non-latching EPO switch is used, the EPO must be held for a minimum of 1
second. This does not apply to a latching EPO switch.
CAUTION: The EPO port is not a phone line surge suppressor; do not connect a phone
line to this port.
UPS Unit State when asserting EPO with AC line present:
LEDs Output
OFF OFF
To restart the UPS unit after asserting EPO with AC line present:
1. Verify that the EPO assertion has been removed or cleared.
2. Remove AC line power to the UPS unit.
3. Reapply AC line power. Now the UPS will start back up in Bypass mode and the LCD will
display "BYPASS MODE".
UPS Unit State when asserting EPO without AC line power:
LEDs Output
OFF OFF
To restart the UPS unit after asserting EPO without AC line power:
1. Verify that the EPO assertion has been removed or cleared.
2. Reapply AC line power to the UPS unit. Now the UPS will start back up in Bypass mode and
the LCD will display "BYPASS MODE".
Internal SNMP/WEB Card Insertion

Remove the small cover panel from the accessory slot to use optional accessories to remotely
monitor and control your UPS. Visit www.tripplite.com/support for more information,
including a list of available SNMP, network management and connectivity products.
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 hardware. See
STEP 5 on page 3 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.
