SPECIAL CONDITIONS OF USE
The Ex Wavelet works with internal battery.There is an optional
connection for an external power supply.
Marked "X" - Conditions to be explained in instructions and in the
Certificate "Special Conditions of Use":
It must be of a suitably certified LPS and SELV Type and output
over voltage and short circuit protected according to the latest
edition of Electrical Safety Standard(s) EN/UL/IEC 62368-1 or
EN/UL/IEC 60950-1 or the equivalent Standard.
The external supply source must be of output ratings at 12VDC
maximum and between 1.65-2.2.
The configured external connection assemblies (combination of
connectors and cables) must be pre-assembled in an ordinary,
non-classified area - not in the presence of an Explosive Atmos-
phere. Installation instructions include information on the selec-
tion of specific sealed connectors and cables to be used in these
assemblies.

An external power supply connection requires that you use a
special safety barrier. The external power supply cannot be
connected directly to the device.
For operating the device on external power supply, please
consult with an Ex technical expert .

The last remaining step in the installation is to be done within the
Explosive Atmosphere, but it must be done with the power supply
disconnected from the equipment (external source and internal
battery supply - via reed switch). Only after all assembly connections
are complete may the external power supply be powered on.
Additionally, the equipment connections must not be disassembled
for service with the power supply energized. Refer to Manufacturer
installation procedures, requirements, and description of compo-
nents used in constructing the harnesses, and to the User Manual
and Installation Guide for Explosive Zone, Ayyeka Ref. 0100592 for
external connection assemblies.
A polarized "Protector" guard, which is part of the Explosive Environ-
ment requirement, is installed over the unit's external connectors to
disable disconnection after the equipment is installed in the Explo-
sive Environment.
The following WARNING is to be marked on the equipment in a
visible area, and the Instruction Manual must include explanations
of these instructions:
Explosion Hazard. Do not open or service the unit or disconnect/
reconnect the connectors in the presence of hazardous atmos-
phere.

INTRINSIC SAFETY
Intrinsic Safety (IS) is an approach to the design of electronic equipment
going into hazardous areas that ensures there are no conditions under
which the equipment can operate that could cause a release of energy
sufficient to ignite a hazardous gas vapor or dust mixture. Devices that
meet the low power, current-limited design criteria are deemed
Intrinsically Safe (IS).
The Wavelet has been certified and tested to worldwide IECEx
(International Electrotechnical Commission Explosive) standards. The
IECEx scheme allows demonstrated compliance for use in Zone 0
(equivalent to Class 1, Division 1 in North America) aeas in the following
countries:
United States India Slovenia Denmark
Germany Russia Croatia Netherlands
Poland Canada Korea Switzerland
Australia Italy South Africa Finland
Hungary Singapore Czech Republic New Zealand
Romania China Malaysia Turkey
Brazil Japan Sweden
