•

Weatherproofness of enclosure is guaranteed only if the cover is in place glands adequately tightened. Damage due to
accidental entry of water can be avoided if the instrument is installed in a rain shade.

•

If the ambient temperature is high, the instrument should not be installed to receive direct sunlight. In case such a position
of shade is not available, a heat shield should be fitted above the instrument especially if the operating temperature lies
between

60

◦

C and

80

◦

C.

•

While screwing the instrument, the hexagonal mounting bush should be turned and not the housing.
