2.4 Regular IFC 090 / CAP-EEx electronics unit
The field cables that enter the terminal compartment of the IFC 090 / CAP-EEx signal converter unit (i.e.
power supply, current and binary outputs) are non-intrinsically safe. To connect external devices to the
signal output terminals, the wiring requirements for the type of protection of the compartment (standard:
increased safety "e", optional: flameproof "d") must be conform to the international or national standard
involved (e.g. EN 60079-14).
The terminal arrangement is shown below.
