Location
Figure 3-1 gives the dimensions of your dc source. The dc source must be installed in a location that
allows sufficient space at the sides and back of the unit for adequate air circulation (see Bench
Operation).
NOTE: This dc source generates magnetic fields that may affect the operation of other
instruments. If your instrument is susceptible to operating magnetic fields, do not locate
it in the immediate vicinity of the dc source. Typically, at three inches from the dc
source, the electromagnetic field is less than 5 gauss. Many CRT’s, such as those used in
computer displays, are susceptible to magnetic fields much lower than 5 gauss. Check
susceptibility before mounting any display near the dc source.
Bench Operation
Do not block the fan exhaust at the rear of the unit.
A fan cools the dc source by drawing air in through the sides and exhausting it out the back. Minimum
clearances for bench operation are 1 inch (25 mm) along the sides.
Rack Mounting
The dc source can be mounted in a standard 19-inch rack panel or cabinet. Table 2-1 documents the part
numbers for the various rack mounting options that are available for the dc source. Installation
instructions are included with each rack mount option.
NOTE: Support rails or an instrument shelf is required when rack mounting units.
