Start-up

The following must be checked before commissioning:
• The correct installation and sealing of the thermowell or protective sleeve (especially when
used as separation element to Zone 0).
• The connection of the potential equalization line (mandatory for dust-ignition proofness).
• The compliance of the electrical specifications with the specified ignition-proof relevant
values.
• The size of the contact resistance and loop resistance according to the protection type.
• The electrical connection and the installation must be performed according to the
"Installation" and "Electrical connection" chapters.
Warning – general risks!
The relevant safety and accident prevention regulations must be complied with.
• The associated technical documentation for the operation of transmitters and indicator units
is to be observed. The technical documentation is also available on the Internet at
