Input Voltage Configuration, Models 120-Asx And 320-Asx - Pacific Power Source ASX series Operation Manual

3.3.2 INPUT VOLTAGE CONFIGURATION, MODELS 120-ASX AND 320-ASX

DISCONNECT THIS UNIT FROM THE INPUT SERVICE BEFORE REMOVING TOP COVER.
HIGH VOLTAGE HAZARD PRESENT INSIDE UNIT WHEN TOP COVER IS REMOVED AND STILL
The 120-ASX and 320-ASX Power Sources have been designed to accept most standard single
phase input voltage forms. This is accomplished through the use of a tapped, dual primary, 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.
Figure 3.3.2 shows the location of the various jumpers which need attention relative to input voltage
form. The position of these jumpers is listed on the accompanying table.
The first step in configuring the input power form is to remove the top cover. Next, connect the
jumpers as stated in the table for the desired input voltage. Jumpers are located on the the input
power transformer (T1). Refer to the table in Figure 3.3.2 for the proper setting.
After configuring the input voltage form, check connections and insure that they are tight and in the
correct position. Replace the top cover.
CONNECTION OF THIS UNIT TO IMPROPER INPUT VOLTAGES WILL CAUSE
READ THE INPUT VOLTAGE LABEL AND CONNECT TO THAT INPUT
VOLTAGE ONLY. IF THERE ARE ANY QUESTIONS, CONTACT THE FACTORY.
The 120-ASX or 320-ASX is then connected to an appropriate outlet via the input power cord.
Refer to Paragraph 2.1.1 for minimum input service requirements of the various input voltage
forms.
