Specific Conditions of Use (X):
1. The Model 5408 Level Transmitter will not pass the 500Vrms dielectric strength test
between the circuits and the earth ground. This must be taken into account during
installation.
2. Plastic wire-on tag, Plastic part of Process Seal Antenna and Non-standard paint
options (paint options other than Rosemount Blue) may cause risk from
Electrostatic discharge. Avoid installation that could cause electrostatic build-up,
and only clean with a damp cloth.
3. Appropriate cable, glands, and plugs need to be suitable for a temperature of 5 °C
greater than the maximum specified ambient temperature for location where
installed.
4. The Transmitter can be installed in the boundary wall between EPL Ga and EPL Gb.
In this configuration, the process connection is EPL Ga, while the transmitter
housing is EPL Gb. Refer to Control Drawing D7000002-885.
