2. Unused cable entries must be filled with suitable blanking plugs
which maintain the ingress protection of the enclosure to at least
IP66.
3. Cable entries and blanking plugs must be suitable for the ambient
range of the apparatus and capable of withstanding a 7J impact test.

Special Conditions for Safe Use (X):
1. The device contains a thin wall diaphragm less than 1 mm thickness
that forms a boundary between EPL Ga (process connection) and EPL
Gb (all other parts of the equipment). The model code and datasheet
are to be consulted for details of the diaphragm material.
Installation, maintenance and use shall take into account the
environmental conditions to which the diaphragm shall be
subjected. The manufacturer's instructions for installation and
maintenance shall be followed in detail to assure safety during its
expected lifetime.
2. Flameproof joints are not intended for repair.
3. Non-standard paint options may cause risk from electrostatic
discharge. Avoid installations that could cause electrostatic build-up
on painted surfaces, and only clean the painted surfaces with a damp
cloth. If paint is ordered through a special option code, contact the
manufacturer for more information.
