10.1.5 Power supply
Electrical connection see Page 48 ff.
Supply voltage Transmitter:
85...260 V AC, 45...65 Hz
20...55 V AC, 45...65 Hz
16...62 V DC
Measuring sensors:
powered by the transmitter
Potential equalisation
For potential equalisation no special measures are necessary.
For instruments for use in hazardous areas, observe the corresponding guidelines in
the specific Ex documentation.
Cable entry Power supply and signal cables (inputs/outputs):
Cable entry M20 x 1.5 or
Cable gland for cables with Ø 6...12 mm
Threaded adapter 1/2" NPT, G 1/2"
Sensor cable connection (see Fig. 48 on Page 46):
A special cable gland allows you to insert both sensor cables (per channel) into the con-
nection compartment simultaneously.
Cable gland M20 x 1.5 for 2 x Ø 4 mm or
Threaded adapter 1/2" NPT, G 1/2"
