High Voltage Connections for Standard Cable
When connecting high voltage cable through the high voltage outlets of the power supply
enclosure, always install the strain relief bushing onto the cutout to insulate cable and
prevent it from arcing to ground. Refer to the installation procedures below:
1. Disconnect line voltage to power supply
2. Remove lid from power supply
3. Remove black insert bushing from cutout of high voltage outlet. Mount strain relief
bushing (P/N 4610634 supplied with power supply) on cutout.
4. Cut a suitable high voltage cable to desired length. Insert cable through strain relief
bushing. Allow additional length for cable to reach high voltage output terminal
block inside power supply.
5. Strip 3/8 inch insulation from end of high voltage cable. Attach cable to one of the
free positions n the high voltage output terminal block.
6. Re-tighten strain relief bushing to fit snug. Pull gently on cable to make certain
connection is secure.
Some static eliminating devices may have a separate insulated ground wire (green)
running along the high voltage cable. This wire must be connected to the ground screw
on the outside of the power supply.
If corona-free shielded cable is used, be sure to connect ground wire to ground terminal
located inside the power supply.
CAUTION
–
Electrical Shock Hazard
Failure to properly ground shielding may result in electrical shock hazard to
personnel and inefficient operation of equipment.
“D” and TrueAC Power Supply
1. Determine the location for mounting the neutralizing bar and power supply. Refer
to
Figure 8
(see
Figure 9
for TrueAC cable connections) for correct cable assembly.
Some cable assemblies have SLCC high voltage connector pre-installed.
2. DO NOT PLUG LINE CORD OF POWER SUPPLY INTO THE INPUT
POWER RECEPTACLE UNTIL INSTALLATION IS COMPLETED.
3. Drill four 9/32” diameter clearance holes for mounting the power supply using
¼-20 hardware. Refer to
Figure 10
for dimensions between clearance holes.
4. Ensure the mounting location of the power supply will allow the high voltage cables
to be positioned away from moving parts and sharp edges then mount power supply.
