accumulation of electrostatic charge, it is necessary to clean the painted surfaces
with a damp cloth.
4. 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.
5. The Transmitter can be installed in the boundary wall between a level Ga and level
Gb location. In this configuration, the process connection is installed in Ga, while
the transmitter housing is installed in Gb. Refer to Control Drawing D7000002-885.
6. Cable entries must be used which maintain the ingress protection of the enclosure
to at least IP65. To maintain the ingress protection ratings, Covers and Sensor
Module to be fully tightened and PTFE tape or pipe dope is required for cable entries
and blanking plugs. See Instruction Manual on application requirements.
7. Using the box provided on the nameplate, the User shall permanently mark the
type of protection chosen for the specific installation. Once the type of protection
has been marked it shall not be changed.
8. The applicable temperature class, ambient temperature range and process
temperature range of the equipment is as follows:
