Installation
•
Observe local regulations and install in accordance with manufacturer's specifi-
cations and the relevant standards and rules.
•
Observe installation instructions of threaded joints (conduits, adapters and ca-
ble glands).
•
Do not operate the device outside of its electrical, thermal and mechanical pa-
rameters.
•
Thoroughly install the housing cover and the threaded joints (cable glands,
adapters and conduits) to maintain the integrity of the flamepaths and the de-
gree of protection of the housing.
•
Also observe the installation instructions for the threaded joints.
•
The o-ring between the housing cover and socket must be inserted for sealing.
•
The base must be completely screwed to the housing.
•
The detector is designed that it does not need to be connected to the local po-
tential equalization. If electrostatic charging cannot be excluded, the detector
must be connected to earth according local requirements.
•
Use suitable connecting cable for the ambient conditions.
•
Connecting cables (conductors and insulation) must be suitable for a continuous
service temperature ≥
T
a
+20 K.
•
Before the use of connection cables, they have to be checked for the possibility
of gas migration, especially if changes of the ambient and/or operating condi-
tions can occur (see also NEC, CEC or IEC 60079-14). For NEC and CEC installations
sealing at enclosure must be provided.
•
Connected lines must be strain-relieved.
•
The detectors are to be used exclusively for fixed location installation.
•
Devices that were used in "non-hazardous areas" must not be used in hazardous
areas.
