3.1 Operation
THIS EQUIPMENT GENERATES DANGEROUS
VOLTAGES THAT MAY BE FATAL.
PROPER GROUNDING OF ALL HIGH VOLTAGE
EQUIPMENT IS ESSENTIAL.
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 G IS REACHED.
Failure to follow these procedures may void the warranty.
A)
Insure the Circuit Breaker is in the OFF position (0).
B)
Check the input voltage rating on the nameplate of
the supply and make certain that this is the rating of
the available power source. Standard SLS Series
units operate on 220Vac, three phase.
C)
PROPER GROUNDING TECHNIQUES:
The E1
ground stud on the rear of the inverter chassis must
be connected to whatever customer system ground is
used: cold water pipe ground, electrical conduit
ground, steel building girder ground, ground rod
ground, etc. This customer provided system ground
cable should be a heavy gauge, mechanically secure
connection. See Figure 3.1 for a typical operating set-
up.
The “bottom end” of the load must be connected to
the ground stud on the bottom of high voltage stack
baseplate using a heavy gauge and mechanically
secure customer provided load return cable.
SLS units are provided with a four conductor line
cord (three phases and safety ground). No specific
phase orientation is required.
D)
Electrically/mechanically attach the high voltage
stack assembly corona dome to the load as seen fit
for the application on hand.
E)
OPTIONS NOTE
: See Section 5 for hook-up and
operating instructions for the options on your unit.
Custom models may also require set-up changes.
F)
For initial turn-on, rotate the KILOVOLT control
fully counter-clockwise to the zero voltage position.
Rotate the MILLIAMPERES control fully clockwise
to the maximum position.
G)
The input power cable may now be connected to the
AC power line.
H)
Switch the front panel circuit breaker to the ON
position (I). (If the supply is to be turned off for an
extensive period of time, the line cord should be
disconnected). The front panel lights should
illuminate. The unit is now in the HIGH VOLTAGE
OFF mode. The green HIGH VOLTAGE OFF light
should be illuminated.
I)
Depress and hold the green HIGH VOLTAGE OFF
switch. The front panel meters will now read the
preset value of the KILOVOLT dial and the
MILLIAMPERES dial (or remote programming
voltages, if used). To preset the desired level of
current and voltage during operation, hold in the
green HIGH VOLTAGE OFF switch and rotate the
appropriate dial while noting the corresponding
meter reading. Release the green HIGH VOLTAGE
OFF switch.
NOTE:
No actual output is being produced at this stage.
J)
Depress the red HIGH VOLTAGE ON switch. The
switch should illuminate and the output will slow
start to the preset level output voltage and/or output
current.
