3.1 Installing the POD

WARNING

Risk of electric shock. Can cause injury or death. Failure to shutdown the Liebert ITA2 and to isolate the system electrically means that the system will

contain deadly high voltage within the unit and at its output terminals. The Liebert ITA2 must be shut down and all local and remote electric input power must be disconnected

before any work may be done on or in the UPS and MBC. This includes the addition, removal or alteration of a power distribution box.

NOTICE

Risk of improper shutdown. Can cause damage to connected equipment. Shutting down the UPS system will result in loss of input power to the connected load. Before beginning, shut down the connected equipment or transfer them to an alternate input power supply. Refer to 4.2 - Shutdown for details about

shutting down the Liebert ITA2 UPS.

To install the POD:

1. Remove the screws attaching the POD port cover panel and retain them for reassembly; see Figure 19.

2. Remove the POD port cover and set aside.

3. Align the POD connectors with those inside the POD port, making sure the colors match; see Figure 20..

4. Verify that the connectors are fully seated.

5. Tilt the top of the POD and insert the lower edge into the slot of the POD port on the Liebert ITA2 MBC.

6. Press the top of the POD toward the enclosure and press it into place. See Figure 21.

7. Attach the POD with the screws removed in Step 1.

Labels on UPS not shown.

4.1 Startup

1. If the two plastic bezel are attached to the Liebert ITA2 MBC, remove them by pulling both ends toward you with equal force.

2. Verify that the Maintenance Bypass Breaker on the front of the Liebert ITA2 MBC is Off (open) and that the breaker interlock is secured in place.

3. Close the feeder breakers in the external panel to provide main input and bypass input (for dual input system).

4. On the front of the Liebert ITA2 MBC, close the rectifier input breaker, bypass isolation breaker and maintenance isolation breaker.

5. If any optional POD’s are installed, verify that any distribution breakers on the POD’s are closed.

6. Start the UPS according to procedures in the UPS user manual, SL-00030. The connected equipment should now be supplied protected power from the UPS.

7. Reinstall the two plastic bezels on the front of the Liebert ITA2 MBC.

4.2 Shutdown

NOTICE

Risk of improper shutdown. Can cause damage to the connected equipment. Shutting down the Liebert ITA2 will disconnect input power to the connected equipment. Before shutting down the UPS, prepare the connected equipment, either by transferring it to an alternate input power source or shutting it down.

If shutting down the Liebert ITA2 UPS is an emergency, either operate the REPO button, if installed, or remove the four-pin connector on the rear of the UPS for communication terminal block Pins 9-12.

To shut down the Liebert ITA2 UPS to take it out of service, follow the procedures in the UPS user manual. Once the UPS has been shutdown, remove the plastic bezel from the front of the MBC to reveal the circuit breakers. Open all circuit breakers to electrically isolate the UPS unit from input power.

4.3 Transfer UPS from Normal Mode to Maintenance Bypass Mode

1. Remove the two plastic bezels from the front of the Liebert ITA2 MBC by pulling both ends toward you with equal force.

2. Transfer the Liebert ITA2 UPS to internal bypass by following the procedures in the UPS user manual, SL-00030.

3. Loosen the thumb screw on the interlock on the Maintenance Bypass Breaker.

4. Slide the interlock up (rack-mount orientation) or to the side (tower orientation) and tighten the thumb screw to secure the interlock in place.

NOTE

When the interlock is moved to unlock the maintenance bypass breaker, the UPS will transfer to internal bypass if it was not already done in Step 2. The connected equipment is now unprotected from power abnormalities.

5. Close the Maintenance Bypass Breaker

6. Open the Rectifier Input Breaker, Bypass Isolation Breaker and Maintenance Isolation Breaker to electrically isolate the UPS module from AC power

7. Open all battery breakers on the rear of each battery cabinet to electrically isolate the UPS module from DC power.

The system is now in maintenance bypass mode to allow the UPS module to be safely serviced.

4.4 Transfer UPS from Maintenance Bypass Mode to Normal Mode

1. Ensure that the mechanical interlock is still secured in the unlocked position.

2. Close the Rectifier Input Breaker, Bypass Isolation Breaker and Maintenance Isolation Breaker on the front of the MBC.

3. The UPS will begin its startup procedure and operate in internal bypass mode. Verify that the UPS is operating in internal bypass mode before proceeding.

NOTICE

Risk of improper operation. Can cause damage to the connected load. Failure to have the UPS operating on internal bypass and performing the next step will result in loss of all output power to the connected equipment.

4. Open the Maintenance Bypass Breaker

5. Loosen the thumb screw on the mechanical interlock and slide it down (rack orientation) or to the side (tower orientation) and secure it in place by tightening the thumb screw

6. Transfer the UPS from internal bypass to inverter power following the procedures in the UPS user manual, SL-00030.

The UPS is now in normal operation, and the connected equipment is supplied with protected power.
