- Observe the approvals of the manufacturer for the tank/pipeline
and the interstitial space.
- The safety instructions in this documentation must be adhered to.
- Only qualified service companies may be used for assembly and
commissioning

.
- Lead-throughs for pneumatic and electric connection lines, through
which the EX atmosphere can carry over, must be sealed gas-tight.
- Comply with relevant regulations regarding electric installation, ex-
plosion protection (e.g. EN 60 079-14, -17), and accident preven-
tion.
- Comply with explosion regulations, e.g. BetrSichV (and/or directive
1999/92/EC and the laws of the respective member states result-
ing therefrom) and
/
or others
- Pneumatic connections, connection lines and fittings must be de-
signed to at least PN 10 for the entire temperature range.
- Before entering inspection chambers, the oxygen content must be
tested and the inspection chamber flushed if necessary.
- If metallic connection lines are used, it must be ensured that the
power supply grounding is on the same potential as the pipe-
line/tank to be monitored.
5.2 Assembly of the Leak Detector
- Wall mounting using the supplied mounting material.
- Outside and inside the Ex-area (zone 1 or 2), in the open air, with-
out any more protective boxes.
If a protective box should nevertheless be necessary for opera-
tional reasons, the protective box must be adequately ventilated.
- Install the housing protected from external mechanical loads. (Test
with low requirements).
- If it is assembled in an enclosed space, it must be well ventilated.
The operator shall apply EN 60 079-10/EN 13 237 as a basis for
evaluation.
- To avoid excessive heating, the leak detector must not be installed
directly next to a heat source.
The ambient temperature must not exceed 55°C; appropriate
measures may need to be taken (e.g., installation of a roof to pro-
tect against sunlight).
- Ventilation systems must be kept clear.
