4.3 Grounding and potential binding
The 9243 amplifier module is ungrounded. The measurement inputs and outputs are isolated
from the supply voltage. Observe the potential binding between the sensor, cable shield and
downstream-connected electronics.
CAUTION
Only applicable to low rated voltages.
4.4 Installation
The mounting rail version is installed on a DIN EN mounting rail.
5 Using the instrument for the first time
DANGER
Electrical shock hazard
Never switch on the 9243 amplifier module if it shows signs of damage incurred in
transit. Only ever use the 9243 amplifier module under the conditions specified in this
operation manual.
DANGER
Electrical shock hazard
Turn on the operating voltage only once all sensors and loads have been connected.
Only connect the device to power supply units which are equipped with a safety transformer
complying with VDE 0551. Transmitters and other components connected in series with the
9243 amplifier module and powered from the mains should also be equipped with a safety
