WARNING
THIS EQUIPMENT GENERATES
DANGEROUS VOLTAGES THAT MAY BE
FATAL. PROPER GROUNDING OF ALL HIGH
VOLTAGE EQUIPMENT IS ESSENTIAL.
IMPORTANT:
Before connecting the power supply to the
AC line, follow this step-by-step procedure.
Do not connect the power supply to the AC
line until Step F is reached.
Failure to follow these procedures may void
the warranty.
A) Insure that the high voltage cable is properly
greased and installed in accordance to the High
voltage cable manufacturer instructions
and terminated
to the load. Insure that all circuits connected to the high
voltage output are safely interlocked against accidental
contact. Insure external load is discharged.
B) Check the input voltage rating on the serial
nameplate of the supply and make certain that this is the
rating of the available power source
C) PROPER GROUNDING TECHNIQUE: The
chassis of high voltage power supplies must be grounded,
preferably to a water system ground using copper pipe or
other earth ground. A ground stud is provided on the front
panel .See Figure 3.1 for a typical operating setup. The
return line from the load should be connected to the power
supply chassis. Using a separate external ground at the
load is not recommended. An IEC 320 connector is
provided for connection to the line voltage source. A
standard line cord is also provided.
D) Hook-up: Connect control and monitoring
connections as described in this manual.
E) For initial turn-on, program the voltage and
current for zero output. Connect the enable/disable signal
to disable.
F) The input power cable may now be connected to
the AC power line.
G) Enable the power supply via the enable/disable
hardware based, dry contact closure.
H) Slowly program the output voltage and current to
desired level. Monitor the output voltage and current via
the monitoring test points. Note equipment operation is
normal, i.e. Load is behaving as predicted.
I) To turn high voltage off, use the enable/disable
signal. If equipment is to be kept off for extended
periods, disconnect power supply from line voltage
source.
WARNING
AFTER TURNOFF, DO NOT HANDLE THE LOAD
UNTIL THE CAPACITANCE HAS BEEN
DISCHARGED!
LOAD CAPACITANCE MAY BE DISCHARGED BY
SHORTING TO GROUND.
WARNING
THE VOLTAGE MONITOR ON THE POWER
SUPPLY FRONT PANEL DOES NOT READ THE
OUTPUT VOLTAGE WHEN THE POWER IS
TURNED OFF, EVEN IF A CHARGE STILL EXISTS
ON THE LOAD.
CAUTION
ALWAYS OPERATE THE UNIT WITH THE COVER
ON. DO NOT ATTEMPT TO ACCESS OR REPAIR
ANY INTERNAL CIRCUITS. DANGEROUS AND
LETHAL VOLTAGES ARE GENERATED INSIDE
THE MODULE.
