UPS Power/Battery Module Removal

Optional Connection continued

Contact-Closure Communication Connection

Use a user-supplied contact-closure DB9 cable B to connect the power module's Dry-Contact port to the communication port on your computer or other equipment. This will allow basic contact-closure signals to be sent to and from the UPS. Refer to diagram 1c and table 1d to determine the signals carried by this port. Install on your computer the Tripp Lite PowerAlert Software appropriate to your computer's operating system.

2EPO Port Connection

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 included cable 2a , connect the power module’s EPO port to a user-supplied remote switch. The pin assignments for the EPO port are shown in diagram 2b . Note: if 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.

3Internal SNMP/WEB Card Insertion

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 (for power module maintenance or replacement)

The UPS system includes a self-contained power/battery module along with an independ- ent, 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”, con- nected 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.

WARNING! For qualified service personnel only. Failure to follow the bypass proce- dure 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.

STEP 1. Disable PowerAlert Software and disconnect communication cables from the communication ports A on the UPS power/battery module.

STEP 2. Press UPS's “OFF” Button C , if the UPS is powered, until you hear a beep and see a “BYPASS MODE” message shown in the LCD Display D .

STEP 3. Turn the detachable PDU's Bypass Switch B to “BYPASS”.

STEP 4. If an external battery module is connected to the UPS E , disconnect it from the UPS.

The UPS power/battery module is now safely powered down and it can be detached

from the PDU to perform maintenance/replacement.
