Permanent Mounting
17.1
Mounting
The detector unit should be mounted in a frame or chassis using the mounting points (
“Appendix A – Technical Drawings” on page 41.
). The unit must be mounted under a cover that
prevents direct contact with an operator. Screws: use M4 screws with 8
mm max thread length
and maximum 5
Nm torque to screw fixings into the mounting points.
17.2
Protective Earthing
A protective earth terminal is located on the back panel. This terminal is used for grounding the
unit to minimize any mains leakage current that might be generated if the primary earth
connection of other equipment or components fails.
The detector must be connected to the nearest available grounding point on an earthed
equipment chassis or frame.
The earthing connection should be able to withstand a continuous current of 40
A. This can be
achieved by installing an earth cable of at least 18
AWG conductor thicknesses, which should be
terminated with crimped ring terminals and secured with screws of 4 mm diameter or larger.
17.3
Cooling
The detector units generate heat during continuous use. This heat must dissipate to the
surrounding air or the equipment in which the detector is installed.
The 2315NDT has forced air cooling provided by fans, which run in the powered-on state. The
air flowing through the detector is sufficient to cool the unit without relying on conductive or
convective cooling provided that the air flows into the entrance fan from the outside of the X-ray
housing, and is expelled such that it does not loop back into the fan inlet.
Baffles or other blocking arrangements can be used to enforce this air flow. Examples of correct
and incorrect arrangements are shown in
Inlet and outlet vents in the housing must each have a cross sectional area of at least 15 cm2.
WARNING
The detector MUST be cooled via forced air cooling system.
