Proper grounding of the power supply enclosure is essential for safe and efficient
operation. Proper grounding can be accomplished by either of the following methods:
1. For power supplies mounted on machinery, connect power supply ground stud with
at least #16 AWG copper wire.
2. All power supplies are equipped with a 3-conductor line cord.
For power supplies with 120 VAC operating voltage, the line cord is fitted with a
standard NEMA 5-15P plug. The line cord must be plugged into a 3-terminal grounded
receptacle.
For power supplies with 230 VAC operating voltage, the line cord is fitted with a
standard NEMA 6-15P plug. The line cord must be plugged into a 3-terminal grounded
receptacle.
For power supplies that are equipped with a plug-less 3-conductor line cord, the ground
wire (green or green/yellow) must be connected to earth ground.
Input Line Voltage Connections
The line cord must be connected to a power source of the correct voltage and frequency
as listed on the nameplate. For power supplies with 120 or 240 VAC operating voltage,
the line cord is fitted with a plug. For power supplies with a plug-less line cord, the
following connections are required:

If the static eliminating equipment is used ton machinery, it is recommended that the
line cord of the power supply be connected to the machine “RUN” button. This enables
the static eliminating equipment to turn on and off with the machine. Some power
supplies are equipped with an ON/OFF switch with indicator.
CAUTION
–
Electrical Shock Hazard
Do not apply line voltage to the power supply until all grounds and high voltage
connections are complete and static eliminating equipment has been installed.
