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 H IS REACHED.
Failure to follow these procedures may void the warranty.
A)
Insure that 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. Spellman SL Series units
operate on 115Vac (220Vac if 220Vac option is
ordered), single phase unless ordered with a different
input voltage.
C)
PROPER GROUNDING TECHNIQUES:
The
chassis of high voltage power supplies must be
grounded, preferably to a water system ground using
copper pipe or other earth ground using the ground
stud B1 at the rear of the unit. See Figure 3.1 for a
typical operating set-up.
The return line from the load should be connected to
the ground pin terminal block TB2-1, on the rear of
the power supply. Using a separate external ground
at the load is not recommended.
10W-300W units are provided with IEC type line
cable. 600W-1200W units are provided with a three
conductor line cord.
WARNING
D)
Attach the output cable to the load.
E)
Plug the high-voltage output cable provided with the
unit into the rear of the supply and hand tighten the
knurled collar.
F)
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.
WARNING
G)
For initial turn-on, rotate the KILOVOLT control
fully counter-clockwise to the zero voltage position.
H)
The input power cable may now be connected to the
AC power line.
I)
Switch the front panel circuit breaker to the ON
position (1). (If the supply is to be turned off for an
extensive period of time, the line cord should be
disconnected). The light inside the circuit breaker
should light up. The unit is now in the HIGH
VOLTAGE OFF mode. The HIGH VOLTAGE OFF
light should be lit.
