Installation and wiring
Type 8045
→ Make sure that the polarizing pin (mark 4 Fig. 9) is on the fitting.
→ Insert the device (mark 1 Fig. 9) into the fitting. Position the
arrow on the side of the device in the direction of the flow: the
totalizers will increment.
→ Tighten by hand the clamp collar (mark 2 Fig. 9).

Danger
Risk of injury due to electrical voltage.
▶ If a 18...36 V DC powered version is installed either in a wet
environment or outdoors, all the electrical voltages must be of
max. 35 V DC.
▶ Disconnect the electrical power for all the conductors and isolate
it before carrying out work on the system.
▶ Observe all applicable accident protection and safety regula-
tions for electrical equipment.
Danger
Danger due to the operation of the relay outputs of a UL
device in a wet location.
▶ If a UL device is used in a wet location:
- energize the relay outputs with an alternating voltage of max.
16 Vrms and 22.6 Vpeak.
- or energize the relay outputs with a direct voltage of
max. 35 V DC.
