5.1.5 Float Charger
While the inverters provide a fast replenishment of
energy following a power quality event, a dedicated
Float Charger is used for float charging to optimize
energy efficiency. The Float Charger also allows
Ultracapacitor based systems to start from a
completely discharged state.
Note:
For the smallest PCS100 UPS-I systems without a
separate Coupling Transformer Enclosure (frame
size 1xB) the Float Charger is installed in the
Termination Enclosure.

5.1.6 Inverter Enclosure
One Inverter Enclosure can hold up to six PCS100
Inverter modules. Where the PCS100 UPS-I requires
more than six inverters, two or more enclosures will
be required. One enclosure is deemed the Master
Inverter Enclosure and the remaining are deemed
Slave Inverter Enclosures.
The Master Inverter Enclosure also houses the Master
Auxiliary Module.
The Graphical Display Module (GDM) is always
mounted in the door of the master Inverter enclosure.
The Slave Inverter Enclosure houses a Slave Auxiliary
Module.
