4.3. Connecting the protective conductor to the UV flame detector
It is critical to connect the exterior "M6 protective conductor connection" to the
enclosure using a ring cable lug. Use a plain washer in front of and behind the
ring cable lug and lock the screw using a serrated lock washer or a spring
washer to keep it from loosening unintentionally.
The cable must be fixed firmly near the enclosure to prevent the cable from
becoming loose.
4.4. Connecting the connector cable to the UV flame detector
Only use screwed cable glands that are approved for the ignition protection type
and the type of cable routing.
Observe the package insert with technical information for the installed screwed
cable glands.
Open the enclosure.
Lead the connection cable with the complete exterior insulation through the
screwed cable gland into the pressure-resistant interior of the UV flame
detector.
(1) Observe the adhesive label when connecting.
When using crimp sleeves, it is critical that they are processed gas-tight
using suitable tools.
(2) Connecting terminals are designed based on push-in direct plug technology
for rigid or flexible conductors with crimp sleeve.
When connecting flexible conductors without a crimp sleeve, the connecting
point is opened with a standard screw driver.
In this regard, also refer to the section
"Tools for assembly"

(3) For shielded connection cables, place the cable underneath the
"grounding clamp = M3" and screw it tight.
Remove the plastic foil from the shield harness.
If necessary, remove any loose metal particles, dirt and traces of moisture from
the pressure-resistant interior of the
UV flame detector.
