Transmitter start up

Startup of the transmitter may begin after installation (section 3, Installation) is successfully completed.
WARNING – Bodily injury. When the housing covers are removed and power is still connected, there is a
potential for explosion. Failure to observe this safety information may result in death or severe injury.
Do not remove housing covers in hazardous (classified) areas or explosive environments unless the area is
known to be non-hazardous. Verify an explosive atmosphere is not present when before applying power with
the housing covers removed.
The following sections discuss in detail the requirements to complete a successful startup.
— Section 4.1, Supplying power
— Section 4.2, Configuring the transmitter
— Section 4.3, Commissioning the transmitter
— Section 4.4, Software configuration security (optional)
IMPORTANT NOTE: Some of the procedures required for startup are also used for maintaining or servicing
the transmitter. It will be necessary to skip to the required procedure located in the maintenance instructions
and return to this section when that is completed.
