Any electrical interference induced onto the conductors of a 4
– 20 mAmp loop, by the installation, must be kept below the
levels necessary to comply with the requirements of EN60079-29-1 or other applicable gas detector performance
requirements / standards.
In practice, this means that peak noise currents induced on the current loop should be no greater than ±0.25 mA.

4.2.1 Handling

Warranty void if opening MetCam enclosure, other than the back cover used for accessing the electrical
connections to the terminal block.

Do not touch MetCam optics with bare hands; take care not to contaminate the optical surfaces with any greasy
substances.
The three MetCam optical surfaces are numbered in the following drawing:
1
– VIS window with lens guard
2
– IR window
3 - Mirror

For cleaning MetCam optics use only wipes approved for optical
equipment with
Isopropyl Alcohol
. Failure to comply could result in
damage.

MetCam is available with M25 or 3/4" NPT ports.

Make sure to use the gland or conduit connector that fits the
MetCam port type.

Using a gland with a flexible cable will allow ease of alignment
and is therefore recommended.
