Shelf Preparation/Mounting
See drawings 030-821-06 and 030-903-06.
NOTE:
Mount the shelf in a clean and dry environment. Allow at least 1.75” of free space above and below the unit for
unrestricted cooling airflow. A customer-supplied DC fan tray can occupy part or all of the required space below
the shelf and it is recommended to allow a minimum of 2RU (3.5”) below a DC fan tray for removal and servicing
of the fans and/or fuses.
Mounting brackets accommodate either 1" or 1-3/4" rack spacing. 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. Use washers, which are designed to cut
through the painted surface (such as internal tooth), or special screws to ensure a good chassis ground.
To attach a 19" rack mount kit, see Figure 6.

Module Insertion/Removal
To insert a module: lift locking bar, place the module on the shelf bottom, and slide the module into the rear
connector (inside of the shelf). Apply pressure on the module handle to engage the rear connector in the shelf
receptacle.
NOTE:
It is recommended that the first module be inserted into the front rightmost position using the side of the shelf as a
guide. The next module may be inserted using the previous module as a guide. Do not force a module into
position if it does not seat properly. All modules are keyed to ensure that the correct module (polarity/voltage) type
is used.
To remove a module: lift locking bar, grasp module handle and pull out, sliding the module away from the rear
connector and out of the shelf.
NOTE:
Replacing a rectifier with a new one requires a manual Inventory Update at the controller before installing the
new rectifier. This command (
Main Menu > Rectifiers > Inventory Update)
clears the removed rectifier from the
controller’s current list of rectifiers.
