WARNINGS:
• Turn off power before servicing any device.
• Please check the ambient and operating temperatures under "Ambient/
Operating Temperature" on page 2 for the specific configuration you
are about to use or install.
• In potentially explosive atmospheres:
- open the enclosure only when SITRANS LC300 is not energized.
The transmitter is in operation when the power supply is switched on.
Note:
