NOTE: The connector should connect only one way, matching the color of the pins.
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 220/127 V.
NOTE: When connecting distribution POD’s to an AS3 or AS4 frame, the L-L output receptacles
connect to the 240-V taps of the output transformer, not to the 208-V tap. Verify receptacle voltage
and load ratings before energizing the load.

3.10.1 Checks before Commissioning/Start-up

2. If using external battery cabinets or 3-party battery systems, verify that the DC-power and
communication cables are connected properly and that all connections are tight.
3. Measure and record the AC-input voltage and frequency. These are required to properly
configure the output voltage of the Liebert APS system.
4. If any modules were removed from the Liebert APS during installation, verify that all modules
are fully-inserted and that the module locking levers are in the locked position.
5. For Remote Emergency Power Off (REPO) circuit:
• If connecting the UPS to a REPO circuit, see REPO (Remote Emergency Power Off) on
page 53 for the connection details and instructions.

the terminal-block Pins 9-10 as described in
Dry-contact Ports on page 52.

place and secure.
