Toshiba 1600XPi Series Installation And Operation Manual page 73

The 1600XPi come equipped with a set of internal backup batteries packaged in sets of 6 batteries per battery pack. See
Appendix A: Specifications for the number of battery packs per UPS model.
HOT SWAPPABLE: The battery packs can be replaced while the UPS is in On-Line or Bypass modes without removing
power from the critical loads.
If a power failure occurs as the battery pack is being removed/inserted or occurs during
the period batteries are out of the circuit, the unit will try to go to Backup (without
battery) and would thus drop the load. It would also arc/spark between the battery and
chassis connections if going to Backup as the tray is pulled.
To perform a hot swap of the battery packs:
1. Open the front door of the 1600XPi.
2. Loosen the battery retaining plate screws and remove the battery pack retaining plate(s).
Each battery pack weighs approximately 40 lb (18 kg).
Dropping or uncontrolled handling of the battery pack may result in personal injury or
damage to the UPS or battery pack.
Use two hand or two person lift to handle each battery pack. Maintain horizontal
orientation of the battery pack with setting it down.
3. Slowly draw out each battery pack half-way, then support the bottom of the pack as the pack is drawn out of it's recep-
tacle.
4. Place the old battery pack aside.
5. Lift the new battery pack using the same technique described above to slide the battery pack half way into the battery
pack receptacle.
Ensure the battery pack is oriented right-side up.
6. Slowly slide the battery pack the rest of the way into the receptacle.
6.1 If oriented correctly, the battery pack will slide all the way into the battery pack receptacle, and a faint but
audible click can be heard when the rear connectors mate.
6.2 If the battery pack does not slide smoothly back completely into the receptacle, remove it and verify the bat-
tery pack is not upside down.
6.3 Notify the factory if the battery pack still will not fully seat in the receptacle, and a cause cannot be deter-
mined.
7. Repeat steps 3-6 for remaining battery packs.
8. Reinstall battery pack retaining plates.
9. Close the front door.
