Warning!
Only appropriately trained personnel are allowed to work on the instrument when
the system is live and is connected to the power supply.
A power disconnect must be installed near the instrument.
Do not start up the instrument until the PE conductor has been connected!
Before connecting the instrument to the input power source, make sure the voltage
matches the voltage rating on the nameplate!
Caution!
All lines conducting signals are to be shielded and run separately from other
control lines.
Note!
Immunity against interference can only be guaranteed if the shielded ground wire
is kept as short as possible. Do not solder an extension onto the shield!
If the instrument is being installed on a post, grounding the post is recommended.
