3.2 Electrical connections.
3.2.1 Safety instructions – Installation.
Isolate the power supply to the measuring device before performing any electrical connection work.
The electrical wiring and cabling work must be performed exclusively by authorized
personnel.
Due to the risk of electrocution, systematically isolate the power supply to the controller
before performing electrical connection work.
Warning for the model supplied with 10 – 30V
Risk of electrocution: do not connect a device operating in mains power mode to a
model supplied with 10-30 V.
Risk of electrocution: the connection of a protective earth (PE) is compulsory when
wiring and cabling both 100-240 Va.c. and 10-30 Vd.c. models.
Warning for wiring the relays
Fire risk. Since the relay contacts have a nominal value of 6 A, the external loads
connected to the relays must be fitted with devices which limit the current to < 6 A.
Open the unit's lower cover to access the controller's wiring terminals.
Unscrew the two screws which hold the lower protective cover.
Before removing the cover, loosen all the cable glands so that the cables can slide in and out.
Figure 3 shows the transmitter's wire connection zone when the lower protective cover is removed.
