Safety instructions

Appropriate use
Zener barriers are used in control and instrumentation systems for the
processing of lower voltages and currents. Zener barriers contain intrinsically
safe circuits that are used to drive intrinsically safe field devices (load cells) in
potentially explosive atmospheres.
Devices which have been operated in general electrical systems, must not be
used afterwards in electrical systems that are in connection with potentially
explosive atmospheres.
To ensure safe operation, the device may only be operated in accordance with
the information given in the Operating Manual. It is also essential to comply
with the legal and safety requirements for the application concerned during
use. The same applies to the use of accessories.
The equipment must not be attached directly to the mains.
General dangers of failing to follow the safety instructions
The Zener barriers correspond to the state of the art and are fail‐safe. The
devices may give rise to remaining dangers if they are inappropriately
installed and operated by untrained personnel.
Any person entrusted with the installation, commissioning, maintenance or
repair of the devices must have read and understood the Operating Manual
and in particular the technical safety instructions.
Conditions on site
Protect the equipment against direct contact with water (IP 20).
Maintenance and cleaning
The Zener barriers are maintenance free. Please note the following points
when cleaning the housing:
- Before cleaning, disconnect the device from the power supply.
- Clean the housing with a soft, slightly damp (not wet!) cloth. In no case
shall you use solvent.
- When cleaning, ensure that no liquid gets into the device or connections.
