Commissioning and Installation Appendix D Linking Device for Zone 2 Explosion and Protection
126 3BDD011677-600 A
• Ensure the installed equipment comply with the types of protection applicable
to the corresponding zones.
• All connected electrical equipment must be suitable for the respective intended
use.
• The operator must ensure protection against lightning in compliance with the
locally applicable regulations.
• Electrostatic aspects must be considered when mounting the bus-modules.
• The hazard of any objects falling onto the bus-module must be prevented.
• If the linking device does not meet the requirements of impact protection,
protection against impact energy and IP protection must be provided at the
place of use as per the requirements stated in section 26.4 of IEC/EN 60079-0.
• The linking device is defined as Instruments and apparatus of low energy
according to clause 23 of IEC/EN 60079-15; thus the requirement stated in
sub-clause C, limiting the transient characteristic to 40% above the rated
voltage, has to be adhered to when erecting the equipment.
Commissioning and Installation
The linking device is mounted in a major system. Depending on the level of IP-
protection, an interval for cleaning the apparatus (dust settlement) must be defined.
Care must be taken that only equipment is installed that complies with the types of
protection relevant to the applicable zones and categories.
The following important facts must be observed:
• The equipment must be installed in a protective enclosure that meets the
requirements for resistance to impact as defined in the IEC/EN 60079-0, cl.
26.4.2. This enclosure must pass the environmental tests according to
IEC/EN 60079-0 standards for the preferred ambient range, that is, it must be
submitted to these tests (thermal endurance, impact and IP, this test sequence
must be observed).
• The equipment must be used only as intended.
• The Functional Earth connection of the apparatus must be connected with the
Protective Earth of the system.
