4.2. Transmitter housing
The transmitter is accommodated in a cast aluminium box coated on the surface with paint of hue RAL 1017.
The box is held by four M5 bolts with hexagonal socket heads. Upon loosening the bolts slightly the box can
be rotated around horizontal axis through ±180°. At the rear part of the box there is a terminal board under a
lid held in position by six bolts with hexagonal socket heads. At the bottom of the box there are cable glands
and a special valve preventing condensation of the air humidity inside the box.
The unused gland openings shall be blinded. The front panel of the box is either blinded (the ECONOMIC
version) or fitted with a two-line background-illuminated display unit and a four-button membrane keypad (the
COMFORT version of the meter).
Prior to putting the meter into operation, check the correct sealing of all active glands, blinding of the unused
ones and tightening of the bolts holding the terminal box lid.
