General Warnings and Cautions
An explosion-proof device may be opened only after power is removed from the device.
An intrinsically safe device loses its license as soon as it is operated in a circuit that does not meet the requirements
of the examination certificate valid in your country.
The device may be operated with high pressure and corrosive media. Therefore, serious injury and/or considerable
material damage cannot be ruled out in the event of handling of the device.
The perfect and safe operation of the equipment is conditional upon proper transport, storage, installation and
assembly, as well as, on careful operation and commissioning.
The equipment may be used only for the purposes specified in this manual.
CAUTION
Electrostatic discharge can damage or cause the failure of semiconductor devices such as integrated
circuits and transistors. The symbol at right appears on a circuit board or other electronic assembly to
indicate that special handling precautions are needed.
• A properly grounded conductive wrist or heel strap must be worn whenever an electronics module
or circuit board is handled or touched. Static control kits are available from most electrical or electronic supply
companies.
• Electronic assemblies must be stored in static protective bags when not installed in equipment.
