3.2 Controller/Interface/STS Shelf Mounting/Preparation
The shelf has been designed for flush or mid-mounting in a 19” relay rack. Mounting brackets are also supplied
for mounting in a 23” rack.
NOTE: The shelf shall be mounted in a clean and dry environment. Allow at least 1.75” of free space in front of the unit
for unrestricted cooling airflow.
1. The shelf should be mounted to the rack using at least two #12
– 24 x 1/2” screws in each bracket. Philips-type screws and
screwdriver should be used to eliminate the possibility of
slippage and scratching of the unit’s exterior. Washers (such as
internal tooth) or special screws that are designed to cut
through the painted surface should be used to ensure a good
chassis ground.
2. Put the shelf into the equipment rack horizontally, and align
holes of mounting brackets and rack.
NOTE: Each INEX controller module or interface module allows maximum
control of 12 inverter units cascaded. It is recommended to have the
controller/interface/STS shelf installed on top of stacked inverter
shelves to ease inter-connections; however, it may be installed
below the inverter shelves if the MBSDU panel is not required.
All input and output connections are made through the knockouts, located in the top and the bottom of each of the
two rear covers, as well as both side panels. The cover on the right is for the controller/interface section, and the
cover on the left is for the STS section.
3. Remove the rear cover(s) to access the shelf backplane and
connectors.
4. Knockouts on top and bottom are for shelf inter-connections. To
remove knockout, snip tabs, move plate up and down until tabs
in back snap apart.
