Figure 5-11 Cell Installation and Latching System
The cell mounting infrastructure consists of a polyglass backplane, cell mounting rails, and
horizontal polyglass supports. Each of the nine Power Cell's three-phase AC input
connections exit at the top right of the Transformer Section, and are routed to the cell via
three large adalets (right enclosure wall) and two lexan wire trays. These trays are located
underneath the cells. The Power Cell's single phase PWM AC output connections are made
in the rear air plenum via bus connections. Projects requiring Cell Bypass will use an
additional bus network scheme to connectand physically mount the bypass. Contactors can
be changed in the field through the front of the enclosure by removing a Power Cell,
disconnecting the subject contactor, and pulling it through the polyglass back plane (only
qualified personnel should access the contactors). The contactors and bus connections are
forced air cooled (see Figures "Nine Cell 40-140 Amp Mounting Structure" and "Bypass
Contactors and Bus Connections"). Projects that do not require Cell Bypass use an
alternative bus connection made between the power cells' T2 and T1 terminals.
Note
A cell lifter, P/N A1A163496.08, may be required to install or remove power cells from the
GenIV System.
