In order to minimize the effects of external electromagnetic fields, connect the chassis of
the camera to an appropriate grounding point via the grounding threads (see Fig. 3.3K).
The same grounding point should be used for both the camera and the computer to avoid
ground loops. If the machinery chassis is in different ground than the computer, the camera
should be electrically isolated from the machinery chassis. If the camera is powered by the
power supply provided with the camera, camera will not be grounded via the power supply
(attach grounding wire to the grounding threads of the camera and the other end of the
grounding wire to the same grounding point as the computer).
The camera unit must be properly protected from excessive radiation, heat/cold, condensation,
vibration or mechanical forces (see Table 3.1 for more detailed specifications). If you feel
uncertain about the correctness of the installation and/or about the suitability of the
environment, please contact your vendor or Cavitar. Warranty does not cover damage caused
by improper installation.
Installation of temperature warning unit
Temperature warning unit should be mounted to an appropriate fixture in such a way that the
indicator leds and buttons are visible and accessible to the operator. If this is not possible, an
additional warning light system (optional) should be applied to ensure that possible alarms
will be noticed and reacted on without delay.
Electrical connections
The electrical connections shall be made in the following way:
• connect the power cable (Fig. 4.9A) between camera unit (Fig 3.3H) and temperature
warning unit (Figs. 4.9B and 3.6H)
• connect the power supply output cable (Fig. 4.9C) to temperature warning unit (Fig.
3.6G)
• connect the power supply input cable (Fig. 4.9E) to the power supply (Fig. 4.9D)
• connect the GigE cable (Fig. 4.9F) between camera unit (Fig. 3.3I) and computer
(computer is not included in the standard system)
• ensure the camera unit housing (Fig. 3.3K) is firmly connected to an appropriate
grounding point. Also ensure the computer is grounded to the same grounding point to
avoid ground loops
Fig. 4.9 shows a typical welding camera system configuration after the connections have been
made. Also spare protective windows (Fig. 4.9G), cooling connectors for air or liquid cooling
(Fig. 4.9H), heat sinks for passive cooling (Fig. 4.9I, optional), thermally conductive sheets
for heat sinks (Fig. 4.9J, optional) and installation CD (Fig. 4.9K) are shown.
