3.1 Operation
THIS EQUIPMENT GENERATES DANGEROUS
VOLTAGES THAT MAY BE FATAL.
PROPER GROUNDING OF ALL HIGH VOLTAGE
EQUIPMENT IS ESSENTIAL.
WARNING X-RAY RADIATION EXPOSURE IS
HAZARDOUS
Failure to follow these procedures may void the warranty.
Check the input voltage rating on the nameplate of the
supply and make certain that this is the rating of the
available power source. The Spellman XRBHR/XRBD
MONOBLOCK
operates on 90-264VAC, single phase
50 or 60Hz.
Bellow Vent hole:
Do not block or insert anything into the vent hole located
on top cover as indicated on the XRBHR data sheet
SHV#128132-001 or XRBD data sheet SHV#128146-001.
This hole provides venting for the internal bellows that
allows for the expansion and contraction of the insulating
oil as temperature varies.
Cooling
:
For convection/forced air cooled models:
The Monoblock® is designed to operate in an ambient
temperature of 0-40 degrees C. For maximum performance
and reliability, it is important that sufficient cooling is
provided to maintain the oil temperature of the
Monoblock® at or below 55 degrees C. Convection
cooling may be sufficient. However, in some applications
an external cooling fan (to be provided by the user) may be
necessary to maintain the oil temperature of the
Monoblock® at or below 55 degrees C. Please see below
for suggest fan placement.
For models with an integrated cooling system:
Models equipped with an integrated cooling system are
designed to operate in an ambient temperature of 0-40
degrees C. For maximum performance and reliability, it is
important that the ambient operating temperature of the
Monoblock® is maintained at or below 40 degrees C.
Preventative maintenance is recommended in order to
keep the fans and heat exchanger free from dust and
debris.
