3 ELECTRICAL CONNECTION
To gain access to the electrical terminal block, the scale plate must be removed. To do
this, slide it to the left by the guide until it be free.
In order to make the electrical connection of the instrument, the limit switch has a screw
terminal strip.
For the electrical installation it is recommended to use multiple conductor cables with
individual cable sections in the order of 0.25 to 0.5 mm
2 in order to make it easier to
connect. Loose cables should not be used given that they can affect the seal of the cable
glands. It is better to maintain the mains cables separated from the cables with low level
signals.
Before starting the installation, check that the cable glands are the right size for the cables
to be used, this will guarantee the instrument will stay watertight. The PG11 cable glands
used are for cables with outside diameters between 6 mm and 10 mm.
Peel the outside insulation to free the inner cables. It is recommended to tin the ends of
the wires to avoid loose ends. Next, feed the cables through the cable glands, and connect
to the corresponding screw terminals. Last, tighten up the cable glands so that they
maintain their degree of protection (IP). The numbering of the terminals is given on the
printed circuit board.
