Precautions of Use
Warning:
Electrostatic sensitive device
Grablink boards may be damaged by electrostatic discharges. Follow the procedure
hereby described and apply any general procedure aimed at reducing the risk associated
to electrostatic discharge. Damage caused by improper handling is not covered by the
manufacturer warranty.
Warning:
Electrostatic compatibility
Grablink boards are compliant with electromagnetic compatibility regulatory
requirements. To ensure this compliance, it is mandatory to secure the card bracket with
the relevant screw according to the procedure hereby described.
Warning:
Risk of electrical shock
Do not operate the computer with any enclosure cover removed. During the hardware
installation, ensure the AC power cord is unplugged before touching any internal part of
the computer.
Warning:
Heating device
In operation, it is normal that a Grablink board dissipates some heat. To ensure the
adequate cooling effect of the fan equipping your computer, it is mandatory to correctly fit
all enclosure covers, including blank brackets.
Warning:
Hot plugging forbidden
Uncontrolled plugging and unplugging of equipment may damage a Grablink board.
Always switch-off the computer, the cameras and any relevant system device when
connecting or disconnecting a cable at the frame grabber or auxiliary board bracket.
Warning:
Poor grounding protection
The computer and the camera can be located in distant areas with distinct ground
connections. Poor ground interconnection, ground loop or ground fault may induce
unwanted voltage between equipments, causing excessive current in the interconnecting
cables. This faulty situation can damage the frame grabber or the camera electrical
interface.
The user must follow proper equipment grounding practices at all ends of the
interconnecting cables. In addition, it is recommended to use cable assemblies with
overall shield solidly connected to the conductive shell of all connectors. Besides the
beneficial effect of cable shielding on electromagnetic compatibility, the shield connection
can increase the protection level against grounding problems in temporarily absorbing
unwanted fault current.
