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!
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.
DANGER!
In potentially explosive areas, the intrinsically safe versions must be used.
The C330X / R330X (intrinsically safe) can be installed in potentially hazardous area zone 0, 1 and
2.
The C330X / R330X (intrinsically safe)can be installed in potentially hazardous area zone 1 and 2
and the input may be connected to temperature sensors installed in zone 0.
The intrinsically safe versions must be supplied by an intrinsically safe power supply unit or
Zener barrier placed outside of the potentially explosive area.
DANGER!
Never connect or operate a non-Ex version of a transmitter in potentially explosive areas,
otherwise it might cause an explosion that can result in fatal injuries! Before you connect and
operate a transmitter version with an Ex approval, always note the following items to avoid an
explosion which may result in fatal injuries
•
Connect the Ex version only to Ex approved sensors or sensors that meet the requirements
for "simple apparatus" in EN 60079-11.
•
Observe the corresponding regulations, the declaration of conformity, the Ex type test
certificate of the device and the relevant instructions of this document.
•
The intrinsically safe versions must be supplied by an intrinsically safe power supply unit or a
Zener barrier placed outside of the potentially explosive area.
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.
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 (applies only to the intrinsically
safe versions).
