 The terminal box to which the equipment is attached must, together with the switch,
ensure the requisite thread engagement for Apparatus Group IIC.
AD Housing: ATEX Approved junction box required.
 The permanently attached cables must be suitably terminated and protected from impact.
 When the switch is attached to an increased safety terminal box, the assembly
must be capable of withstanding the impact test specified in BS 5501: Part 1: 1997.
 The sealing arrangements must maintain the minimum IP54 rating required by the
increased safety enclosure.
 The switch must attach to the enclosure using an existing entry.
 The apparatus may have a combined nameplate which carries multiple approvals
(Intrinsic Safety & Flameproof). The equipment should be marked as to which
protection method it is installed as, and shall not be changed or utilized in any
other manner than was originally marked by the end user.
 To minimize the risk of electrostatic discharge, clean only with a damp cloth.
NOTE: These circuits are all part of the same IS circuit meeting the requirement of 30V max
and 1A max. You cannot connect a zener barrier to C/NO/NC circuit and another barrier to
C2/NO2/NC2 circuit unless the combination of the two barriers is intrinsically safe and is
less than 30V and 1A.
NOTE: For IS, there must be no connection to GND if the switch circuit is connected to a
shunt zener diode safety barrier.
