SPECIAL CONDITIONS FOR SAFE USE
The 'X' suffix to the certificate number relates to the following special condition(s) for safe use:
• 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
conditions (such as high-pressure steam), which might cause a build-up of electrostatic
charge on non-conducting surfaces.
• The end user must ensure that an ingress protection of at least IP65 is maintained at
each entry to the enclosure by use of a blanking element or cable entry device that meets
the requirements of the protection concepts type 'n' or increased safety 'e' or flameproof
'd' .
• The supply to the equipment shall be rated for a prospective short-circuit current of not
more than 10 kA and shall be protected by a suitably-rated fuse
