Communications

“SMART” DB9 Port: Your UPS’s DB9 port can be used to monitor and control your UPS using either RS-232 or dry contact protocols. It can also be used to connect an emergency power off switch.

RS-232 communications are very complex but are easy to implement. The easiest way to monitor and control the UPS using RS-232 is to connect the UPS to a computer with a DB9 cable and install Tripp Lite’s PowerAlert software on the connected computer.

Dry contact communications are simple, but some knowledge of electronics is necessary to configure them. The DB9 port’s pin assignments are shown in the diagram at the left. If the UPS battery is low, the UPS sends a signal by bridging pin 1 and pin 5. If utility power fails, the UPS sends a signal by bridging pin 8 and pin 5. To shut the UPS down remotely, send a 5V to 12V signal on pin 3 (using pin 5 as the (negative) ground) for at least 3.8 seconds.

You may connect your UPS to an EPO switch and a computer at once using a Tripp Lite EPO cable (not included; order accessory #73- 0901 from Tripp Lite). Follow the connection procedures included with the EPO Cable.

Troubleshooting

The UPS’s control panel lights will turn on in the sequences below to signal that the UPS is having operational difficulties.

Lights (On/Flashing) and Condition	Solution
On: REPLACE BATT	Let the UPS system charge for at least
Condition: Replace Battery	12 hours and perform a self test using
	the "ON/Test Switch" as described on
	page 5. If the light continues to stay on,
	contact Tripp Lite for service.
On: BATT LOW, ON BATT	Prepare for imminent UPS shutdown.
Condition: Battery Low
On: BYPASS, LINE, LOAD, OVERLOAD	Reduce the load the UPS supports.
Condition: On Bypass due to Overload
On: FAULT	Remove the cause of the short circuit
Condition: Short Circuit	from the UPS output.
Flashing: FAULT	Check the utility line for wiring problems
Condition: Wiring Fault	such as reversed line and neutral or a
	missing ground.
On: FAULT, REPLACE BATT	Restart the UPS. If the problem persists,
Condition: Battery Voltage too High	contact Tripp Lite for repairs.
On: FAULT, REPLACE BATT, OVERLOAD	Restart the UPS. If the problem persists,
Condition: EEPROM Error	contact Tripp Lite for repairs.
On: FAULT, BYPASS, LINE, 100%	Restart the UPS. If the problem persists,
Condition: On Bypass due to	contact Tripp Lite for repairs.
High Output Voltage
On: FAULT, BYPASS, LINE, 75%	Restart the UPS. If the problem persists,
Condition: On Bypass due to	contact Tripp Lite for repairs.
Low Output Voltage
On: FAULT, BYPASS, LINE, 50%	Restart the UPS. If the problem persists,
Condition: On Bypass due to High	contact Tripp Lite for repairs.
Bus Voltage
On: FAULT, BYPASS, LINE, 25%	Restart the UPS. If the problem persists,
Condition: On Bypass due to Low	contact Tripp Lite for repairs.
