evident, immediately contact the shipping company and Pacific Power Source.
Select an appropriate location for the unit. Key points to consider when locating the chassis
are:
1. PROXIMITY TO THE LOAD - The power source should be located as close to the
load as possible. This helps to reduce distribution losses. These losses become
more critical as the output frequency increases.
2. VENTILATION - The chassis requires good ventilation to adequately cool the internal
components.
requirement for each model is listed below.
Minimum Clearance Requirement
12 inches front and back
2 inches on each side and
12 inches to the rear
When the power source is placed in a 19 inch rack, it must be supported by either chassis
slides or full depth angle brackets. The front panel alone will not support the weight of the
power source. Chassis slides are available from Pacific Power Source as a cost option.
Call factory service for details.
After the location for the unit is selected, verify that the input voltage of the power source is
correct (Input voltage is stated on the system ID label). If it requires changing, refer to
Paragraph 3.3 for instructions.
Also check that the output transformer ratio is correct. If not, reconfigure to the desired ratio
as directed by Paragraph 3.2.
After the input voltage form and output transformer ratio have been verified, set the power
source into the rack or set it into its final position. Make input and output connections as
stated in paragraphs 3.3 and 3.4, respectively.
If either the Remote Interface (GPIB or RS-232) or External Sense feature is to be used, refer
to paragraphs 3.5 and 3.7 for connection.
Airflow ranges from 200 to 1200 CFM.
