4.2. Electronic unit box
The signal-processing electronic unit is accommodated in a cast aluminum 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 of the box is a terminal
board under a lid held in position by six bolts with hexagonal socket heads. At the rear bottom part 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 fitted with a two-line background-
illuminated display unit and a four-button membrane keyboard.
Prior to putting the meter in service, check the correct sealing of all active glands, blinding of the unused
ones and tightening of the bolts holding the terminal board lid.
