The manufacturer's instructions for installation and maintenance
shall be followed in detail to assure safety during its expected
lifetime.
2. Flameproof joints are not intended for repair.
3. Appropriate cable, glands, and plugs need to be suitable for a
temperature of 5 °C greater than the maximum specified
temperature for location where installed.
4. The applicable temperature class, ambient temperature range and
process temperature range of the equipment is as follows:
•
•
•
5. Non-standard paint options (paint options other than Rosemount
Blue) may cause risk from electrostatic discharge. Avoid installation
that could cause electrostatic build-up on painted surfaces, and only
clean the painted surfaces with a damp cloth.
6. Display glass shall be positioned in such a way as to minimize the risk
of mechanical impact.
