Note: The HF Series radiographic systems are compatible with any
automatic collimating system that provides an isolated nor-
mally open switch that closes when the Automatic Collima-
tion System presents an “EXPOSURE READY” mode to the
control; they are also compatible with any beam limiting
device that complies with 21 CFR Subchapter J intended for
radiographic equipment.
POWER REQUIREMENTS
In order to assure the proper operation of our equipment and subsequently, the produc-
tion of high-quality radiographs, it is essential that all power requirements, as specified in
the tables that follow, are suitably met by the facility in which the equipment is installed.
This includes usage of the proper size conductor between distribution transformer and dis-
connect switch, connection to a supply transformer of sufficient capacity (specified in
terms of KVA), insuring the AC input voltage tolerance meets specification (±5% or ±10%
depending on model), and voltage regulation of 5% at full load is maintained. All wiring
and grounding at the installation site must be in accordance with applicable National Elec-
tric Code (NEC) and/or local electrical codes.
THe generator requires a 3-phase "Y" connection, measured line-to-line, balanced to
earth or neutral. The "Y" connection can be 4-wire (L1, L2, L3, Neutral) and GND or
3-wire (L1, L2, L3) and GND. The 4-wire connection may be required by local electri-
cal code and in connection where a roughly balanced 3-phase source exists (e.g.,
when using a delta-to-Y transformer).
Note that failure to comply with the above requirements not only may result in
improper generator operation and/or performance, but it will also void the warranty,
as the warranty is exclusive of the following conditions:
• "Failure of customer to prepare the site or provide power requirements or
operating environmental conditions in compliance with any applicable
instructions or recommendations of QMI.
• "Failure of customer to provide the proper incoming power required to support
the equipment in accordance with the recommendation of QMI.
• "Improper or extraordinary use of the Product, improper maintenance of the
Product, or failure to comply with any applicable instructions or
recommendations of Quantum Medical Imaging, LLC.
