WARNING!
Thermometers must be earthed if dangerous voltages could be expected at the
connection wires (caused, for example, by mechanical damage, electrostatic
discharge or induction)!
6.1 Electrical connection
CAUTION!
■ Damage to cables and wires, and to connection points must be avoided
■ Leads with bare ends must be finished with end splices (cable preparation)
■ Both the internal effective capacitance and inductance must be considered
The electrical connection is to be made according to the sensor connections shown below:
