Pre-condition: A 24 V (DC) supply cable (± 20%) must be planned for power
supply to the pre-amplifier.
NOTICE
Devices that have not been designed for an operating voltage of 12 V DC
(protected against reverse polarity) may not be operated with a voltage of
24 V. This applies to devices with the special numbers 74, 75, 90, 110, 137,
138, 151 and 167. Please consult the manufacturer in the case of special
numbers > 169.
