Shutdown Procedure

Single UPS Operation (continued)

After following all warnings listed in the Safety section and precautions listed above, start-up UPS according to the following procedure:

Step 1. Turn on (close) the “RESERVE INPUT” Breaker. The LCD Screen will display “Bypass Mode”.

Step 2. Turn on (close) the “RECTIFIER INPUT” Breaker and wait about 30 seconds. The DC BUS voltage will be built up to about 393V DC.

Step 3. Locate the external fuse block(s) on the battery module(s) and turn on (close) the fuses.

Step 4. Simultaneously press the “ON” and “” Buttons and hold for 3 seconds. The inverter will turn on and voltage will build for about 30 seconds. The load will be transferred to the inverter. The LCD Screen will display “Normal Mode”.

Step 5. Measure the voltage on the UPS Output Breaker to determine if it is normal or abnormal. If the output voltage is normal, close the Output Breaker to supply the load. After approximately 30 seconds, the UPS will automatically execute a battery test.

This procedure removes power from and shuts down the UPS.

Step 1. Turn off (open) the “UPS OUTPUT” Breaker.

Step 2. Simultaneously press the “OFF” and “” Buttons and hold for 3 seconds. When the reserve power has returned to normal (where its voltage and frequency are within the set range), the power module's inverter will turn off immediately. Support of the equipment load will be transferred to reserve power. The LCD Screen will display “Bypass Mode”.

Step 3. Locate the external fuse block(s) on the battery module(s) and turn off (open) the fuses.

Step 4. Turn off (open) the “RECTIFIER INPUT” Breaker.

Step 5. Wait approximately 5 minutes for the DC capacity to discharge. Press the “ON” and “OFF” Buttons to test the inverter for adequate discharge of DC capacity, and then simultaneously press the “OFF” and “” Buttons to turn off the inverter. Confirm that BUS voltage is safe.

Step 6. Turn off (open) the “RESERVE INPUT” Breaker.

Manual Maintenance Bypass Procedure

This procedure allows for routine maintenance by qualified service personnel. Tripp Lite recommends a routine maintenance inspection every six months. Note: since the power module's inverter is bypassed during this procedure, the UPS will not be able to switch to Back-Up Mode and support connected equipment in the event of a power failure.

Manual Maintenance Procedure (ON Bypass)

Step 1. Simultaneously press the “OFF” and “” Buttons and hold for 3 seconds. When the reserve power has returned to normal (where its voltage and frequency are within the set range), the power module's inverter will turn off immediately. Support of the equipment load will be transferred to reserve power. The LCD Screen will display “Bypass Mode”.

Step 2. Locate the external fuse block(s) on the battery module(s) and turn off (open) the fuses.

Step 3. Turn off (open) the “RECTIFIER INPUT” Breaker.

Step 4. Wait approximately 5 minutes for the DC capacity to discharge. Press the “ON” and “OFF” Buttons to test the inverter for adequate discharge of DC capacity, and then simultaneously press the “OFF” and “” Buttons to turn off the inverter. Confirm that BUS voltage is safe.

Step 5. Turn on (close) the “MANUAL BYPASS” Breaker. Support of the equipment load will transfer to manual bypass. The LCD Screen will display “Manual Bypass”.

Step 6. Turn off (open) the “UPS OUTPUT” Breaker, the “RESERVE INPUT” Breaker and the auxiliary power (+) and fan power (N) fuse isolators. The LCD Screen will go dark.

Note: When the UPS is in Maintenance Bypass Mode, no high voltages will be present within the UPS power module except at the terminals and the “MANUAL BYPASS”Breaker.

Manual Maintenance Procedure (OFF Bypass):

Step 1. Turn on (close) the “UPS OUTPUT” Breaker, the “RESERVE INPUT” Breaker and the auxiliary power (+) and fan power (N) fuse isolators. Support of the equipment load will transfer to manual bypass. The LCD Screen will display “Manual Bypass”.

Step 2. Turn off (open) the “MANUAL BYPASS” Breaker. Support of the equipment load will transfer to reserve power. The LCD Screen will display “Bypass Mode”.

Step 3. Turn on (close) the “RECTIFIER INPUT” breaker and wait approximately 30 seconds. The DC BUS voltage will be built up to about 393V DC.

Step 4. Locate the external fuse block(s) on the battery module(s) and turn on (close) the fuses.

Step 5. Simultaneously press the “ON” and “” Buttons and hold for 3 seconds. The inverter will turn on and voltage will build for about 30 seconds. The load will be transferred to the inverter. The LCD Screen will display “Normal Mode”.
