ATTENTION:
Electrical connection of the Differential pressure indicator is to be done by spe-
cialists (e.g. electricians) to prevent damages. In any case the connection cables
are to be seperated from mains supply before.
CABLE PREPARATION:
Beforer connection prepare the cable ends with tin or cable end sleeves.
CONTACTS:
The contacts are switched according to the above-mentioned circuit diagram. The respecti-
ve differential pressure, engraved into the display (
∆
p1,
∆
p2) controls the contacts (f1, f2).
Each contact is associated a clamp on the reverse of the differential pressure indicator. This
is protected with a sealed aluminum cover.
The clamp description is found on the the plate and on the upper side of the casing.
Connection to earth can be either made via the clamps or the brass-screws which hold the
plate. At loss of these screws they are absolutely to replace, because they serve simultane-
ously as fastening bolts for the plate.
CONNECTION:
Before connection to the clamps, the cable must be led through any kind of PG-11 cable
screw, the cluminum cover and it´s gasket. Subsequently the cables can be connected ac-
cording to the above-mentioned circuit diagram. The max. tightening moment is 2Nm.
Finally the aluminum cover is to be screwed with the casing.
