3.3 Special Hazards
In addition to all standard regulations, the appropriate existing codes or regulations must also be
followed.
If you do not comply with the appropriate regulations, serious injuries and/or damage can occur!
A protection from electrostatic discharge (ESD) is required.
The proper use of grounded work surfaces and personal wrist straps is required when working with
exposed circuitry (PCB, printed circuit boards), in order to prevent static discharge from damaging
sensitive electronic components.
Do not use this instrument in safety or emergency stop devices. Incorrect use of the device can result in
injury.
There is a danger of death caused by electric current.
Upon contact with live parts, there is a direct danger of death.
Electrical instruments may only be installed and connected by skilled electrical personnel.

- Check if the DTW transmitter was delivered in complete assembly.
- Inspect the DTW for possible damage during transportation. Should there be any obvious
damage, inform the transport company and supplier immediately.
- Keep the packaging, as it offers optimal protection during transportation.
- Make sure to protect the connecting contacts from damage.
The digital temperature transmitter DTW is a universal measuring transmitter for resistance thermometers and
potentiometers. It is configurable via PC. The device transforms resistance values or relations (potentiometer)
into a proportional current signal. At the same time the sensors are constantly tested to ensure faultless operation.
The temperature transmitter complies with the requirements of:
- Explosion protection (varies with version)
- Electromagnetic compatibility according to NAMUR-recommendation NE21
- Signaling at analog output according to NAMUR-recommendation NE43
- Sensor break signaling according to NAMUR-recommendation NE89 (Corrosion monitoring of sensor
connection)
