ROOM REQUIREMENTS
3.1 ENVIRONMENTAL REQUIREMENTS
LINE POWERED GENERATORS
Storage / Transport Environmental
Conditions
Temperature range of -40 to 70 degree C.
Relative Humidity range of 10 to 100%
Atmospheric Pressure range of 600 hPa to 1060 hPa
Operating Environmental
Conditions
Temperature range of 10 to 70 degree C.
Relative Humidity (no condensing) range of 30% to 75%
Atmospheric Pressure range of 700 hPa to 1060 hPa
Heat Output
In normal environmental circumstances the maximum heat output of the
equipment can reach 0.220 kW (751 btu/hr).
Components must not be allowed to overheat. Overheating of components
can cause system malfunction.
3.2 ELECTRICAL REQUIREMENTS
This generator contains advanced circuitry, which will maintain the selected X-ray techniques during adverse
line conditions. However, there is a limit to the Generator’s ability to correct for inadequate line power.
To insure proper operation:
• Do not undersize the Distribution Transformer.
• Size feeder and ground wires per this document.
• Ensureandmaintaininputmainsvoltagetospecication.Ensure that the ground resistance is lower
than 10 ohms.
Thepowerrequirementsgivenhere(wiresizes,etc.)aretherecommendedspecication.Withtheexception
of high current carrying conductors and grounds, low voltage connections are made with pre-terminated
wires.
The installation should comply with all the electrical requirements
indicated in this document. These requirements should be
upgraded if local Standards are more stringent.

- For lines below or above 240 VAC requires matching the autotransformer to the supply line.
- Instructions in the installation document and labels in the x-ray console provide instructions for Line
Strap Adjustments.
3.5 LINE POWERED GENERATORS – RECOMMENDED WIRE SIZE
Correct sizing of the feeder wires is critical to proper Generator operation. Wire size is dependent on the
Generator power, the line voltage and the distance from the Distribution Transformer to the Generator Cabinet.
The maximum voltage drop during an exposure must not exceed 5% of the normal mains value.
It is recommended that the Distribution Transformer (Hospital, etc.) used as power source have at least a
power of 25% more than the maximum power of the X-ray Generator.
Recommended wire sizing is indicated in Table 3-1. These lengths are measured from the Distribution
Transformer to the Room Electrical Cabinet (room disconnect). From the Room Electrical Cabinet to the
Control Console (AWG 8) may be used as long as the length does not exceed 3 m (10 feet).
