Appendix D Linking Device for Zone 2 Explosion and Protection Environment Commissioning and
3BDD011677-600 A 127
• The linking device is only operated in a fully mounted and intact enclosure, if
the enclosure is damaged, the operation is not permitted.
• If ambient temperature exceeds 58°C at the place of installation, the
temperature of the connecting cables increases. Hence ensure that,
– temperature of the cables does not exceed 80°C
OR
– suitable cables are used that can withstand temperatures of minimum
90°C.
• When the package is removed, ensure that dirt does not enter the enclosure or
the plugs.
• The equipment must be protected against accidental opening, a warning sign
Warning - Do not separate when energized must be installed near the plugs.
• The connecting plugs must be secured using a torque of min. 0.3 Nm.
• If the parts of the plugs are loosened due to vibration during the operation, then
the plugs must be provided with a light firm varnish to secure the screws. An
extraction force of 0.5 Nm has to be achieved at an equivalent thread.
• Open or not securely closed sockets should not be energized in the Ex-
atmosphere.
• To circuits of Zone 2, only such equipment are connected that is suitable for
operation in this zone and is certified accordingly (Ex Certificate for the
conductive equipment documents have been provided).
• The devices must be protected from Ultraviolet light exposure.
• The device must be connected at low inductance with the Protective Earth of
the system.
• Spare parts are ordered as complete units giving the material number stated on
the device (marking, type label).
• Do not put stress on the system by bending or torsion.
• Inside the potentially explosive atmospheres, assembly must be performed
considering the locally applicable rules of erection into account. The following
directions must be observed:
