The 3000 System Isolators and Converters must be connected to limited output
NEC Class 2 circuits, as outlined in the National Electrical Code
®
(ANSI / NFPA 70),
only. If the devices are connected to a redundant power supply (two separate
power supplies), both must meet this requirement.
Where installed in outdoor or potentially wet locations the enclosure shall at a
minimum meet the requirements of IP54.
Warning: Substitution of components may impair suitability for zone 2 / division 2.
Warning: To prevent ignition of the explosive atmospheres, disconnect power
before servicing and do not separate connectors when energised and an explosive
gas mixture is present.
Warning: Do not mount or remove devices from the power rail when an explosive
gas mixture is present.

IECEx KEM 10.0068X ............................................. Ex nA IIC T4 Gc
KEMA 10ATEX0147X ............................................. II 3G Ex nA IIC T4 Gc
For safe installation the following must be observed. The device shall only be
installed by qualified personnel who are familiar with the national and international
laws, directives and standards that apply to this area.
Year of manufacture can be taken from the first two digits in the serial number.
The devices shall be installed in a suitable enclosure providing a degree of
protection of at least IP54 according to EN60529, taking into account the
environmental conditions under which the equipment will be used.
When the temperature under rated conditions exceeds 70°C at the cable or conduit
entry point, or 80°C at the branching point of the conductors, the temperature
specification of the selected cable shall be in compliance with the actual measured
temperature.
Provisions shall be made to prevent the rated voltage from being exceeded by
transient disturbances of more than 40%.
For installation on power rail in Zone 2, only Power Rail type 9400 supplied by
Power Control Unit type 9410 is allowed.
