=-50 °C to 80 °C, T6 T
a
=-50 °C to 65 °C, Ga/Gb
Special Conditions for Safe Use (X):
1. The device contains a thin wall diaphragm. Installation, maintenance and use shall take
into account the environmental conditions to which the diaphragm will be subjected.
The manufacturer's instruction for maintenance shall be followed in detail to assure
safety during its expected lifetime.
2. In case of repair, contact the manufacturer for information on the dimensions of the
flameproof joint.
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:
 T4 for –50 °C
≤
T

≤
80 °C with T process = –50 °C to 120 °C
 T5 for –50 °C

≤
65 °C with T process = –50 °C to 65 °C
5. The Transmitter can be installed in the boundary wall between an area of EPL Ga and the
less hazardous area, EPL Gb. In this configuration, the process connection is installed in
EPL Ga, while the transmitter housing is installed in EPL Gb.
I7 IECEx Intrinsic Safety
Certificate: IECEx BAS 13.0110X

+70 °C)
Special Conditions for Safe Use (X):
1. The Model 4088 MV Transmitters fitted with transient protection are not capable of
withstanding the 500V test as defined in Clause 6.3.13 of IEC 60079-11:2012. This must
be taken into account during installation.
2. The Model 4088 MV enclosure may be made of aluminum alloy and given a protective
polyurethane paint finish; however, care should be taken to protect it from impact or
abrasion if located in a Zone 0 area.
