    System Operation 3.1 General description of the system An Intrinsically Safe system is composed by an assembly of intrinsically safe apparatus, associated apparatus and interconnecting cables, where the following definitions apply: • Simple Electrical Apparatus Apparatus in which neither of the following electrical parameters are exceeded: 1.2 V 0.1 A (Generated) 20 mJouIes (Stored) 25 mW (Dissipated), in this case the Apparatus does not require any certificate or labeling.

  • Page 32: Grounding Information

    3.4 Grounding information Grounding of intrinsically safe circuits is not required when connected to associated apparatus having galvanic isolation between intrinsically safe circuit and all the other circuits. Should grounding be necessary, for functional reasons, only one point of the intrinsically safe circuit must be grounded. In case of using shielded cables, proper shield grounding (if needed) shall be provided at one point only.

  • Page 33: Installation And Configuration

    Installation and Configuration 4.1 Unpacking Upon receipt of the materials it is recommended to check immediately the integrity of the packing and their contents. If there is any indication or evidence of shipping damage the equipment should not be moved or unpacked. Moving the equipment to a remote storage or holding area may unfavourably affect the owner’s shipping insurance protection.

    5 for details. The blue colour of terminal blocks identifies the hazardous side connections. Wires of this side must be segregated according to standard BS5345 Pt. 4, ANSI/ISA RP-12.6 or to other applicable national regulations. To properly identify each signal Elcon can supply labels to be fixed on the Termination Board.

  • Page 35: Electrical Connections

    Operating Temperature definition Elcon Isolators are small, highly integrated electronic devices, which permit high-density installations. Although Elcon products benefit from special low-power design techniques, it can be necessary to take into account the internal power dissipation when dealing with operating temperature issues.
  • Page 36 0.2 W Temperature Accuracy The accuracy provided in the standard Elcon specifications for analogue units is at an operating temperature of 23 °C, after a 15 minutes warm-up and in the “reference conditions” as described at the beginning of section 4.9.

  • Page 37: Cabinet Heat-Dissipation

    4.10 Cabinet Heat-Dissipation For integration into cabinets, or other enclosures that restrict free air movement, the expected temperature rise within the enclosure should be calculated. Normal practice is to design for a 10 to 20 °C ambient temperature rise inside a cabinet. The cabinet should be provided with top and bottom louvers to provide convection air flow. The use of cabinet fans is recommended for high module density installations.
  • Page 38 ) Forced ventilation with heat exchanger in closed panels: It can be used when either the “harsh” environments or the high dissipated power don’t allow for natural convection. A heat exchanger with a fan pulls the air into the cabinet and forces it into the heat exchange plates that are cooled by the external ambient air moved by a second fan.
