Capacitive load
With capacitive loads elevated switch-on currents arise. These can be reduced by
series-connecting resistors in the supply line.

5.3 Electrical mounting of the transmitter
Requirements for voltage supply
Power supply: DC 10 ... 30 V
The supply must be made via an energy-limited circuit in accordance with IEC 61010-1.
Requirements for electrical connection
Cable diameter matches the cable bushing of the mating connector.
■
Cable gland and seals of the mating connector are correctly seated.
■
With cable outlets, no humidity can ingress at the cable end.
■
Requirement for shielding and grounding
The transmitter is grounded via the process connection of the gas density monitor. The
transmitter is connected with the process connection of the gas density monitor via the
mounting.
