6.3.2 Power System Size
In a power system, up to five (5) rectifier shelves may be stacked and connected to the same controller.
6.3 Power System Assembly and Mounting
6.3.1 Mounting and Grounding a Rectifier Shelf
NOTE:
Mount the shelf in a clean and dry environment. Allow at least 1.75" of free space in
front of the unit for unrestricted cooling airflow. Sufficient free space must be provided
at the front and rear of the power system. This is to meet the cooling requirements of
the rectifiers and to allow easy access to the power system components.
The 19" and 23" shelves have been designed for mid mounting in a standard EIA relay rack. Mounting brackets ac-
commodate either 1" or 1-3/4" rack spacing.
Options for flush mounting in a 19" or 23" rack are also available, but require additional mechanical support at the
rear of the unit unless connected to bus bars
1. Mount the shelf to the customer-provided rack using at least two #12 – 24 x 1/2" screws in each bracket. Use
Phillips type screws and screwdriver to eliminate the possibility of slippage and scratching of the unit’s exterior.
2. Connect the shelf chassis ground (Figure 7) to the rack. On the rack, use thread-forming screws and star
washers that remove any paint or non-conductive coatings and establish metal-to-metal contact to ensure a
proper electrical bond.
