Heat Output
In normal environmental circumstances the maximum heat output of the equipment can reach:
-- for Line Powered Generators 0.16 kW (544 btu/hr)
-- for Capacitor Assisted Generators 0.20 kW (682 btu/hr)
-- for Battery Powered Generators 0.26 kW (890 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 w hich will maintain the selected
X-ray techniques during adverse line conditions. However, there is a limit to the
Generators ability to correct for inadequate line power.
To ensure proper operation:
• Do not under size the Distribution Transformer (Line Powered
Generators). It is recommended that the secondary of Distribution
Transformer has a “Star” configuration.
• Size feeder and ground wires per this document.
• Ensure and maintain input mains voltage to specification. Ensure that
the ground resistance is lower than 10
Ω.
The power requirements given here (wire sizes, etc.) are the recommended
specification. With the exception of high current carrying conductors and
grounds, low voltage connections are made with preterminated wires.
The installation should comply with all the electrical
requirements indicated in this document. These
requirements should be upgraded if Local Standards were
more stringent.
