2.4 poWeR ReqUiReMents
• Ensure that the power connector for the Newton camera is inserted securely. The connector is keyed to
aid correct orientation.
• Power Input: 100 - 240V, 50 - 60Hz, 1.6A.
• The electrical mains lead should be certied for use in your country and in applicable countries the plug
must be tted with a 240V 5A fuse.
• If users use any other power supply they do so at their own risk.

SECTION 3: INSTALLATION
WARNINGS:
• PRIOR TO COMMENCING INSTALLATION, THE USER SHOULD REFER TO THE SAFETY AND WARNING
INFORMATION AND UNPACKING INSTRUCTIONS AT THE BEGINNING OF THIS MANUAL.
• CABLES SHOULD BE ROUTED TO PREVENT ACCIDENTS, DAMAGE AND ACCIDENTAL UNPLUGGING WHILE
AVOIDING BEND RADII OF LESS THAN 30 MM.
• FOR FURTHER INFORMATION ON SO AND SY MODELS PLEASE REFER TO SECTION 5.
• TEMPERATURE AND HUMIDITY MUST MEET THE SPECIFICATIONS DEFINED IN TECHNICAL SPECIFICATIONS.
3.1 tRanspoRt and stoRage infoRMation
• Storage Temperature: -30°C to 50°C.
• If it is to be stored after use at a temperature below the coolant freezing point, ensure that all liquid coolant has been
expelled from the camera.
3.2 MoUnting tHe neWton Using tHe MoUnting flange
The standard Newton mounting ange has mounting holes for 4x M4 ttings. For further information, refer to the
mechanical drawings in Appendix B. For SO models refer to Section 5.
3.3 attacHing to MoUnting posts
There are three holes that can be used if required with the 1/4 - UNC mounting posts with 1” spacing.
For further information, refer to the mechanical drawings in Appendix B.
3.4 c-MoUnt
An optional C-mount adapter is available for standard Newton models.
3.5 connecting tHe neWton to tHe pc
The appropriate PCIe card should be available in the control PC.
USB 2.0
• Connect the USB 2.0 cable from the Newton to a suitable USB 2.0 slot on the control PC.

Newton
3.6 connecting tHe neWton to tHe poWeR sUpply
• Connect the power cable between the Camera power input (rear panel) and the PSU.
• Connect the power cable of the PSU to the mains supply.
3.7 connecting acooling systeM
The Newton can use either air cooling, or optional liquid cooling for deep cooling.
3.7.1 iMpoRtant consideRations WHen Using liqUid cooling systeMs
• Before attempting to remove the coolant hoses, ensure that all coolant has been drained from the hoses and
integral coolant channel within the camera head.
• Care must be taken to avoid permanent damage to the camera system resulting from either leakage of
coolant during connection/removal of hoses or spillage of any residual coolant contained within the camera
head once the hoses have been removed.
• Always ensure that the temperature of the liquid coolant circulated through the camera head is above the
dew point of the camera ambient temperature and humidity conditions. Refer to the Dew Point graph in
Appendix C for guidance.
• Use of coolant at or below the dew point can result in permanent damage to the camera head, due to
formation of condensation on internal components.
• When using a liquid cooling system it is recommended that an overpressure device is tted to avoid
leaks that may nd their way to the mains electricity supply and create a hazard.
• Never use damaged, split or worn hoses.
• The coolant connectors are factory tted and sealed, they cannot be removed.
• Always remove residual coolant from the camera head if the camera is to be stored after operation-
especially if the storage conditions are below the freezing point of the coolant.
3.7.2 cooling Hose connectoRs
There are two cooling hose connectors that are located on the top plate of the camera for connection of the Newton to
a water cooler, or re-circulator system. One end is inserted into the camera body, the other end is barbed for push-t
connection to suitable tubing.
• Coolant Hose Connectors: Two push-t hose connectors are factory tted and sealed, suitable for connection
to 6 mm [0.25”] internal diameter soft PVC tubing / hose
• Recommended tubing: 10 mm [0.4”] outside diameter, i.e. a wall thickness of 2 mm [0.08”]. Alternative hose
dimensions and materials should be thoroughly tested to ensure a leak tight seal is achieved with the barbed
connectors.

3.8 coolant RecoMMendations
• Coolant temperature: Refer to the temperatures specied in Technical Specications for the specic model. Note that
cooling performance may be affected by distance between camera head and cooler.
• Recommended coolant: water or water/glycol mix depending on the ambient environmental temperature during operation.
De-ionized water (without additives) may be used as the coolant. Some mains supply water is heavily mineralized (i.e.
“Hard”) which could cause deposits in the water circuit inside the camera. This can reduce the ow-rate and cooling
efciency. The specied cooling performance of the camera can be achieved with coolant ow rates of 2 litres per
minute, the maximum recommended pressure of coolant circulating through the camera head is 2 bar (30 PSI).
3.9 connecting tHe liqUid cooling systeM
An overview for connecting a liquid cooling system is outlined below- please refer to the information supplied with your
cooling system for further information.
3.9.1 connecting tHe coolant Hoses
1. Remove the black rubber protective caps (x2) if tted.
2. Press the hoses onto the connectors on the camera.
3. Conrm the hoses are connected securely.
4. Connect the other ends of the coolant hoses to the cooling system- refer to the cooling system manual.
