B.2 Instructions specific to hazardous area installations
10.The certification of the transducers rely upon the following materials used in their
construction:
11.If the equipment is likely to come into contact with aggressive substances, then it is the
responsibility of the user to take suitable precautions that prevent it from being adversely
affected, thus ensuring that the type of protection is not compromised.
– Aggressive substances: for example, acidic liquids or gases that may attack metals, or
– Suitable precautions: for example, establishing from the material's data sheet that it is
Specific conditions of use
The apparatus shall only be supplied from a circuit containing a suitably rated fuse having a
breaking capacity of at least 1500 A.
Parts of the enclosure may be non-conducting and may generate an ignition-capable level of
electrostatic charge under certain extreme conditions. The user should ensure that the
equipment is not installed in a location where it may be subjected to external influences, which
might cause a build-up of electrostatic charge on non-conducting surfaces.
Any open face of the XPS-10, XPS-15 or XPS-30 Transducer shall only be installed so that the face
is not substantially subjected to light.
