2.5.5 Connecting Integrated Power Output Distribution (POD)
The rear panel of the Liebert APS UPS provides the capability to add integrated distribution outlets
(PODs) as an option to allow direct AC power connection of the supported equipment to the UPS.
These PODs are intended to allow the user to install and even change distribution, if necessary as
equipment changes, while the UPS is still providing power. Follow these steps to properly and safely
add or change the optional PODs.
1. Ensure that the POD breaker is in the Off position.
2. Using a Phillips screwdriver, remove the two screws that are at the top of the POD cover plate
and retain these for reattaching the POD.
3. Remove the POD cover plate to expose the POD connectors.
4. Insert the bottom of the POD into the slot provided, and then connect the POD connectors.
5. Secure the POD by using the two screws removed in Step 2.
6. Repeat Steps 1 through 5 to install a second POD on the Liebert APS (only the 16-bay frame has
two POD ports).
7. Connect the equipment to the appropriate outlets.
8. Close the POD breaker(s) to connect AC power to the outlets.
9. After commissioning the UPS, turn On the connected equipment per the manufacturer’s
instructions (see 2.5.6 - Commissioning/Startup Procedures).
2.5.6 Commissioning/Startup Procedures
The Liebert APS can be commissioned with or without AC power being connected. Follow these steps
for the initial UPS system startup:
Checks Before Commissioning/Startup
___ 1. Verify that the AC power connections are wired properly and all connections are tight.
___ 2. If using external battery cabinets or third-party battery systems, verify that the DC power
and communication cables are connected properly and all connections are tight.
___ 3. Measure and record the AC input voltage and frequency. This will be needed to properly
configure the output voltage of the Liebert APS system.
___ 4. If any modules within the Liebert APS system were removed during installation, verify that
all modules are fully inserted and that the module locking levers are in the locked position.
___ 5. If the UPS is being connected into a Remote Emergency Power Off (REPO) circuit, refer to
3.3 - REPO (Remote Emergency Power Off) for the REPO connection details and
instructions. If no REPO circuit is required or used, the factory-installed jumper must be
removed from the terminal block Pins 9-10 as described in 3.2 - Dry Contact Ports.
___ 6. Verify that the UPS internal bypass breaker is in the open position with the guard in place
and secure.
NOTE
This is the breaker located near the POD port.
NOTE
The two connectors should connect only one way, matching the color of the connectors.
NOTE
Distribution PODs PD2-101, PD2-102, PD2-103, PD2-104, PD2-105, PD2-106 and PD2-107
should not be used if the UPS output voltage is set to 220/127V.
