Input Voltage Configuration, Models 112-Amx And 312-Amx - Pacific Power Source AMX Series Operation Manual

SECTION 3 INSTALLATION

3.3.2 INPUT VOLTAGE CONFIGURATION, MODELS 112-AMX and 312-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 112 and 312-AMX Power Sources have been designed to accept most standard single
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.
Figure 3.3.2 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. Jumpers are located on 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 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 112 or 312-AMX 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.
