Rectifier Shelf
The maximum # of Rectifier Modules per 4RU Main Shelf
is 4. If an Expansion shelf is used then 4 additional Rectifier
Modules. For details on the Expansion shelf, see Section 3.3.
Preparation for Rack Installation
The installation location should be clean and dry. The Rectifier Shelf requires a minimum of at
least 50cm clearance at the front and sides. The Rectifier Modules pull air in from the front so the
front of the Shelf should be clear of any obstructions or other items to allow for adequate airflow.
Note:
All Shelf components except Rectifier Modules, Rack Temp cable, and Batt Temp cable have
been factory-installed.
AC Input Protection
The end-customer shall ensure that the appropriately sized and rated AC input protection devices
(such as fuses or circuit breakers) and properly sized cables are installed by trained personnel.
DC Output Terminal Block Protective Cover
The Main Shelf and the Expansion Shelf each
have a clear protective cover mounted over
the DC Output terminal block (see
Figure 2
).
The cover is held in place by 2 mounting screws
for easy access for cable installation and other
maintenance. When work is completed or the
shelf will be left unattended, always replace the
protective covers over the terminal blocks.
