Specific Conditions of Use (X):
1. The Model 5408 Level Transmitter will not pass the 500Vrms dielectric strength test
according to clause 6.3.13 GOST 31610.11-2014 (IEC 60079-11:2011) between the
circuits and the earth ground. This must be taken into account during installation.
2. The Model 5408 Level Transmitter with an aluminum alloy housing, that are painted
by paint, other than Sherwin Williams, Polane HS Series (V66V29 Catalyst), can
accumulate electrostatic charge on the surface of the casing. Therefore, to avoid
accumulation of electrostatic charge, it is necessary to clean the painted surfaces
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 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.
5. 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.
6. 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.
7. The applicable temperature class, ambient temperature range and process
temperature range of the equipment is as follows:
Temperature class /
Maximum surface
temperature Ambient temperature range Process temperature range
IIC/ IIIC
T2/T250 -60 °C ≤ Ta ≤ 70 °C -60 °C to 250 °C
T3/T200 -60 °C ≤ Ta ≤ 70 °C -60 °C to 195 °C
T4/T135 -60 °C ≤ Ta ≤ 70 °C -60 °C to 130 °C
T100 -60 °C ≤ Ta ≤ 70 °C -60 °C to 100 °C
T85 -60 °C ≤ Ta ≤ 70 °C -60 °C to 85 °C
