Output Frequency - Pacific AMX series Operation Manual

SECTION 3 INSTALLATION
3.1 CHASSIS PLACEMENT
The first step in setting the chassis into place is to remove it from its shipping container. The next step is to
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.
Airflow ranges from 200 to 1200 CFM. A minimum of 12 inches front and back clearance is
recommended for proper operation of the Models 125-AMX, 140-AMX, 160-AMX, 320-AMX, 345-
AMX, 360-AMX, 390-AMX, and 3120-AMX. The air intake for the Models 105-AMX, 108-AMX,
112-AMX, 305-AMX, 308-AMX, 312-AMX, and 320-AMX is located on both sides near the front. A
minimum clearance of two inches on each side and 12 inches to the rear is required for proper
operation of these models.
When the chassis 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 chassis. Chassis slides are available from
Pacific Power Source as a cost option. Call factory service for details.
After the location for the chassis 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 voltage range is that which is desired. If not, reconfigure to the desired form as
directed by Paragraph 3.2.
After the input voltage form and output voltage range have been verified as correct, slide the chassis 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.
