ELECTRICAL WIRING
Pic.3
The conductors forming the signal carrying cable connected to the microswitch (Pic. 1)
must have an adequate cross-section so that the current density, in each conductors,
2
is no higher than 4 A/mm . One of these is used only for the earthing of the level gauge.
The cross-section of the conductors must also be adequate in relation to the overall
lenght of the cable used to avoid drop in voltage along it, over the values prescribed
by the regulations on the subject.
It is likewise recommended to use flexible cables with an adequate outside diameter
for the fair-leads used (not supplied), to ensure a perfect seal of the cable clamp
on the signal carrying cable.
For connections to the microswitch terminals use eyelet cable terminals.
The membrane level gauge
MN-03
has two 1/2" Gas cable inputs. If one of these is
not used, it must be closed with the supplied PVC plug.
CAUTION: there is a screw inside the casing, near the right-hand cable input, whose
position is marked by the ground symbol (Pic. 3), and it is used for the earthing of
the membrane level gauge. This screw must be connected to the yellow-green conductor (only green for the USA)
of the signal carrying cable. The ground connection of the membrane level gauge, through the yellow-green conductor,
