I7 IECEx Intrinsic Safety

Certificate: IECEx BAS 09.0004X

Standards: IEC 60079-0:2011, IEC 60079-11:2011;

Markings: Ex ia IIC T4/T5 Ga, T4(-60 °C

≤ T

≤ +70 °C),

T5(-60 °C ≤ T

≤ +40 °C);

See Table 16 at the end of the Product Certifications

section for Entity Parameters.

Special Conditions for Safe Use (X):

1. The surface resistivity of the antenna is greater than

1GΩ. To avoid electrostatic charge build-up, it must

not be rubbed or cleaned with solvents or a dry cloth.

2. The power module may be replaced in a hazardous

area. The power module has surface resistivity greater

than 1GΩ and must be properly installed in the

wireless device enclosure. Care must be taken during

transportation to and from the point of installation to

prevent electrostatic charge build-up.

3. The enclosure may be med from aluminum allow with

a protective polyurethane paint finish; however, care

should be taken to protect it from impact or abrasion

when located in Zone 0.
