WARNING
Physical access
Unauthorized personnel may potentially cause significant damage to
and/or misconfiguration of end users’ equipment. This could be
intentional or unintentional and needs to be protected against.
Physical security is an important part of any security program and
fundamental to protecting your system. Restrict physical access by
unauthorized personnel to protect end users’ assets. This is true for all
systems used within the facility.
CAUTION
Hot surfaces
The transmitter and process seal may be hot at high process
temperatures. Allow to cool before servicing.
Note
Be careful not to scratch or otherwise damage the PTFE sealing.
