OPERATION
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 H is reached.
Failure to follow these procedures may
void the warranty.
A)
Insure that the CONTROL POWER ON
switch on your remote interface fixture is in the
OFF (out) position.
B)
Check the input voltage rating on the
nameplate of the supply and make certain that this
is the rating of the power source to be connected.
DF3/FF3 units operate on 220VAC single phase,
unless ordered with a different input voltage.
C)
Proper Grounding Technique: The chassis
of the high voltage power supply must be
grounded to the local earth ground and also to the
tube housing ground. See Figure 3.1A, 3.1B and
3.1C for typical operating setup.
A three-wire cable is provided for connecting to
the AC supply. The Green wire is for chassis
safety ground connection.
D)
Connect the X-ray cable to the X-ray tube
housing.
E) Connect
the
X-ray
cable to the power
supply. Insure the connector and housing is clean.
Generally vacuum grease or oil is not required but
can be used if desired. Tighten the cable collar to
the connector housing.
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.
G)
For initial turn on, set the kilovolt control
fully counter clockwise to the zero position.
H)
The input power cable may now be
connected to the AC power source.
