In order to install an FI-UPM, the UPS cabinet needs to have upgradeability,
which is determined by the power rating of the static bypass. For example, if the
static switch is rated for 40 kW and the UPS contains one 20 kW UPM, it is
possible to add another 20 kW UPM to it.
For a listing of the upgradeable configurations, see Table
2
.
CAUTION
Only an authorized Eaton Customer Service Engineer or other qualified
service personnel authorized by Eaton are allowed to install an FI-UPM.
Note: Check the cable and fuse rating before power upgrades!
3.6 Battery system
The battery system provides short-term emergency backup power to safeguard
operation during brownouts, blackouts, and other power interruptions. By
default, UPS is configured to use VRLA batteries. If other type of batteries or
other energy storage means need to be connected, consult a certified service
technician prior to proceeding with the installation.
The Eaton 93PS 8–40 kW UPS are equipped with internal batteries to provide
full load runtime of 5–60 minutes depending on the UPS rating. This does not
apply to the C-model, which has no internal batteries. In addition, external
battery cabinets can be introduced to the system to allow extended autonomy.
Internal and external batteries can be used in parallel.
For detailed battery specifications, see Chapter
9
.
3.7 Basic system configurations
UPS power rating
The maximum attainable UPS system power rating is determined by the size of
the UPS cabinet frame. The number of UPM power modules determines the
nominal power rating of the UPS. If upgradeability is required, the system static
bypass should be chosen according to the future maximum load rating, and the
number of UPMs is chosen according to the Day 1 capacity requirements.
