Safety Information Specific to Explosion Protection
!
Warning!
DO NOT OPEN PRODUCT HOUSING!
No repairs requiring opening the product housing are permitted.
Failure to observe this precaution will void the certification and the warranty.
The product is certified for use within the ambient temperature range of -20 °C to +60 ºC and
must not be used outside this range.
The certification of this equipment depends upon the maintenance of the flamepaths and the
use of the following materials in the construction of exposed parts: Aluminum (BS-EN755 1997
6082T6); Stainless Steel (BS-EN10088 No.1.4404). The maximum constructional gaps (Ic) of
the cylindrical flamepaths are less than that required by Table A of EN 60079-1:2007, as
detailed below:
Flamepath Maximum Gap (mm)
Between the tilt center bore and tilt bearing housing shaft (2 off) 0.089
Between the yoke arm bore and tilt resolver shaft 0.061
Between the yoke arm bore and yoke arm blanking cap shaft 0.061
Between the yoke arm bore and yoke spigot shaft 0.061
Between the pan body top bore and yoke spigot shaft (2 off) 0.061
Between the upper cover bore and wiper motor mount shaft 0.060
Between the wiper motor mount bore and base flange shaft 0.100
The pan body to pan body top are to be secured with cap head M5 - 0.8 x 10 mm long S316
stainless steel grade A4/70 special fasteners.
If the equipment is likely to come into contact with aggressive substances (for example, acidic
liquids or gases that may attack metals, or solvents that may affect polymeric materials), then
the user is responsible for taking suitable precautions that prevent it from being adversely
affected, thus ensuring that the type of protection provided by the equipment is not
compromised. “Suitable precautions” include regular checks as part of routine inspections or
establishing from the material’s datasheets that it is resistant to specific chemicals.
The camera is designed for use with flammable gases and vapors covered by apparatus groups
IIA, IIB, and IIC, and with temperature classes T1 to T6.
