Power Module Channel Assignment
The slot location of a power module in the mainframe determines the channel assignment of the
module. When viewed from the rear, the module next to the ac mains connector is always output
channel one. Numbering continues sequentially to the left, from 1 up to 6.
Double-wide power modules are assigned the number of the lowest numbered slot in which is
installed. For example, if a double-wide module is installed in slots 3 and 4, it is assigned channel
number 3. The next adjacent higher numbered module will be assigned channel number 5.
Bench Installation
Do not block the air intake at the front and side, or the exhaust at the rear of the unit.
Refer to the dimension diagram for details.
Never stack more then three mainframes on top of one another in a free-standing
installation.
The unit must be installed in a location that allows sufficient space of at least 3 inches (7.62 cm) at the
front and back, and 1 inch (2.54 cm) along the side of the unit for adequate air circulation.
Four self-adhesive feet are shipped with the mainframe. If desired, install the feet on the bottom of the
chassis - one on each corner. Do not install the feet on the front frame.
