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 protected by a suitably-rated fuse.
