4.1 Safety instructions
DANGER!
All work on the electrical connections may only be carried out with the power disconnected. Take
note of the voltage data on the nameplate!
DANGER!
Observe the national regulations for electrical installations!
CAUTION!
Before you connect and operate a transmitter, always note the following items to avoid an
electric shock:
• For all work on the electrical connections use an electrostatic safe (i.e. grounded)
workplace! In this way you minimize the risk of electrostatic discharge (ESD).
• Assure that the cover was closed after any work on the device. The cover prevents
electrostatic discharge if the solder pads are touched inadvertently; furthermore it protects
the solder pads against dirt.
WARNING!
Observe without fail the local occupational health and safety regulations. Any work done on the
electrical components of the measuring device may only be carried out by properly trained
specialists.
INFORMATION!
Look at the device nameplate to ensure that the device is delivered according to your order.
Check for the correct supply voltage printed on the nameplate.
INFORMATION!
The transmitter is protected against polarity reversal. No damage will occur to the device if the
polarity of the supply voltage is switched. The output will then indicate 0 mA.
INFORMATION!
The calibration of this transmitter works with potentiometers. Therefore assure that the
transmitter is protected against heavy impacts or strong vibrations. Otherwise the calibration
data could change.
