Input Power Wiring Requirements - Pacific AMX series Operation Manual

3.3.8 INPUT POWER WIRING REQUIREMENTS

This paragraph describes the input wiring requirements for the AMX-Series Power Sources. Wire size and
connection techniques are discussed.
• LETHAL VOLTAGE PRESENT AT INPUT TERMINALS OF THIS MACHINE.
• ALWAYS CONNECT "CHS or GND" TERMINAL TO EARTH POTENTIAL.
FAILURE TO DO SO WILL CREATE A SHOCK HAZARD.
The Models 105-AMX, 108-AMX, 112-AMX, 305-AMX, 308-AMX, 312-AMX, and 320-AMX are supplied
with an input power cord. Install an appropriate plug onto the end of the power cord and connect to the proper
outlet. Refer to paragraph 2.1.1 for recommended input service of the configured input voltage form.
The input power of the Models 125-AMX, 140-AMX, 160-AMX, 345-AMX, 360-AMX, 390-AMX, and 3120-
AMX is connected to the Input Power Terminal Block located on the rear panel of the power source. In this
case the input wiring is brought to this terminal block from the distribution panel. The connection points are
labeled "A," "B," "C," "N," and "CHS." The input wiring is connected to these points in the appropriate order
with CHS being the safety ground or earth potential. The AMX-Series Power Source is not sensitive to phase
rotation of the input voltage. For all standard DELTA input voltage forms (208, 220, and 240 VAC) and WYE
input voltage forms (220/380 VAC, 240/416 VAC, and 277/480 VAC), the "N" terminal is not used. Refer to
Figure 3.3.8 for the proper wire size to be used with the configured input power form.
• 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.
NOTE:
It is the user's responsibility to meet all local and national electrical codes when
