WARNING: electric shock hazard. Before making the electrical
connections, the appliance must be disconnected from the mains
power supply and must be prevented from being powered on.
Electrical disconnection must be verified by measurement.
NOTICE:
• check that the unit's power supply voltage corresponds to the rated
data shown on the product label;
• do not power on the unit if tilted or upside down: the transducers may
be damaged.
Connect the power cable to the terminal block through the cable gland.
NOTICE: to avoid unwanted interference, the power cables should be
kept separate from the probe signal cables.
