3.3.7 INPUT VOLTAGE CONFIGURATION, MODELS 140-AMX, 160-AMX, 345-AMX,
360-AMX, 390-AMX, & 3120-AMX
• 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 140-AMX, 160-AMX, 345-AMX, 360-AMX, 390-AMX, and 3120-AMX Power Sources have 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
systems may be used with input frequencies of up to 440 Hz. Contact the factory for details.)
Figure 3.3.7 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. Refer to the table in Figure 3.3.7 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
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 AMX-Series Power Source is then connected to an appropriate distribution panel via an input power cord.
Refer to Paragraph 2.1.1 for minimum input service requirements of the various input voltage forms.
