4.2 Disassembly
WARNING
Incorrect disassembly
The following dangers may result through incorrect disassembly:
- Injury through electric shock
- Danger through emerging media when connected to the process
- Danger of explosion in hazardous area
In order to disassemble correctly, observe the following:
•
Before starting work, make sure that you have switched off all physical variables such
as pressure, temperature, electricity etc. or that they have a harmless value.
•
If the device contains dangerous media, it must be emptied prior to disassembly. Make
sure that no environmentally hazardous media are released.
•
Secure the remaining connections so that no damage can result if the process is started
unintentionally.
4.3 Instructions for installation
Note
Protect the pressure transmitter from:
•
Direct thermal radiation
• Rapid temperature fluctuations
•
Severe soiling
• Mechanical damage
The installation location is to be as follows:
•
Easily accessible
• As close as possible to the measuring point
•
Vibration-free
• Within the permitted ambient temperature values
Note
Perform position error correction
After installation of the pressure transmitter, perform a position error correction to
compensate any zero offset (work offset) arising from the installation location.
