Input Voltage Configuration, Model 320-Amx - Pacific Power Source AMX Series Operation Manual

SECTION 3 INSTALLATION

3.3.3 INPUT VOLTAGE CONFIGURATION, MODEL 320-AMX

WARNING
DISCONNECT THIS UNIT FROM THE INPUT SERVICE BEFORE REMOVING TOP COVER.
HIGH VOLTAGE HAZARD PRESENT INSIDE UNIT WHEN TOP COVER IS REMOVED
AND STILL CONNECTED TO INPUT SERVICE.
The 320-AMX Power Source has been designed to accept most standard three phase input
voltage forms. This is accomplished through the use of a tapped input power transformer.
Configuring the proper input form is simply a matter of setting jumpers in the appropriate
positions. The system is designed for use with input frequencies of 47 to 63 Hz. (Optionally,
the system may be used with input frequencies of up to 440 Hz. Contact the factory for
details.)
Figure 3.3.3 shows the location of the various jumpers which need to be moved to change
input voltage form. The position of these jumpers is listed on the accompanying table.
To change the input power form, remove the top cover, then connect the jumpers as stated in
the table for the desired input voltage. Refer to the table in Figure 3.3.3 for the proper
setting.
After configuring the input voltage form, check connections and ensure that they are tight and
in the correct position. Replace the top cover.
CAUTION
CONNECTION OF THIS UNIT TO IMPROPER INPUT VOLTAGES WILL CAUSE
CATASTROPHIC DAMAGE TO THE POWER SOURCE.
READ THE INPUT VOLTAGE LABEL AND CONNECT TO THAT INPUT VOLTAGE ONLY.
IF THERE ARE ANY QUESTIONS, CONTACT THE FACTORY.
The 320-AMX is then connected to an appropriate distribution panel via the input power cord.
Refer to Paragraph 2.1.1 for minimum input service requirements of the various input voltage
forms.
