4. Intended Use
The device is only approved for appropriate and intended use.
Ignoring these instructions will void any warranty and absolve
the manufacturer from any liability.
The device is an Ethernet-APL Field Switch which provides intrinsically
safe outputs for connecting 2-WISE and FISCO devices.
The device is an associated apparatus according to IEC/EN 60079-11.
The intrinsically safe output circuits may lead into Zone 0.
The intrinsically safe output circuits may lead into Zone 20.
The device is an electrical apparatus for hazardous areas of Zone 2.
The device may be installed in gas groups IIC, IIB, and IIA.
The device may be installed in the non-hazardous area.
5. Improper Use
Protection of personnel and the plant is not ensured if the device
is not used according to its intended use.
If circuits with type of protection Ex i are operated with non-intrinsically
safe circuits, they must no longer be used as circuits with type of
protection Ex i.
6. Specific Conditions of Use
The device must be installed and operated only in a controlled
environment that ensures a pollution degree 2 (or better) according to
IEC/EN 60664-1.
The device must be installed and operated only in surrounding enclosures
that
comply with the requirements for surrounding enclosures according to
l
IEC/EN 60079-0,
are rated with the degree of protection IP54 according to
l
IEC/EN 60529.

7. Mounting and Installation
Do not mount a damaged or polluted device.
Mount the device in a surrounding enclosure.
Ensure that the surrounding enclosure can only be opened with a tool.
The device can get very hot during operation. To protect the device from
excessive heating, observe the required clearances and sufficient
ventilation when installing the device.
Use the device only within the specified ambient and operating conditions.
Observe the mounting position of the device.
The device must be installed and operated only in a controlled
environment that ensures a pollution degree 2 (or better) according to
IEC/EN 60664-1.
If used in areas with higher pollution degree, the device needs to be
protected accordingly.
The device must be installed and operated only in an environment of
overvoltage category II (or better) according to IEC/EN 60664-1.
Supply the device with a power supply that meets the requirements for
safety extra-low voltage (SELV) or protective extra-low voltage (PELV).
7.1.
Requirements for Connectors
Only use the terminals which are supplied with the device.
Ensure that the terminals are in good condition and are not damaged
or corroded.
Observe the tightening torque of the terminal screws.
Observe the permissible core cross section of the conductor.
Observe the insulation stripping length.
Use only one conductor per terminal.
When using stranded conductors, crimp wire end ferrules
on the conductor ends.
When installing the conductors the insulation must reach
up to the terminal.
Only manipulate the connections within the specified ambient temperature
range.
Temperature range
Observe the permissible cable type and cable length given in the
respective hazardous area certificate.
Only use cables and connection lines with a temperature range
appropriate to the application.
7.2. Hazardous Area
Observe the installation instructions according to IEC/EN 60079-14.
The device provides a grounding terminal to which an equipotential
bonding conductor with a minimum cross section of 4 mm
connected.
Observe the warning markings.
7.2.1. Requirements for Usage as Associated Apparatus
Observe the installation instructions according to IEC/EN 60079-25.
Observe the installation instructions according to IEC/EN TS 60079-47.
The intrinsically safe circuits are not galvanically isolated from each other.
Disconnect the terminal of the intrinsically safe circuit
at the associated apparatus before installing any components
in this intrinsically safe circuit.
Connect the terminal of the intrinsically safe circuit only if all components
are installed and connected.
Ensure that the terminals are in good condition and are not damaged
or corroded.
Keep the separation distances between all non-intrinsically safe circuits
and intrinsically safe circuits according to IEC/EN 60079-14.
Observe the compliance of the separation distances between two
adjacent intrinsically safe circuits according to IEC/EN 60079-14.
Intrinsically safe circuits for field connections are not allowed to be
connected together in any mode.
For intrinsically safe circuits, the dielectric strength of the insulation against
other intrinsically safe circuits and against the shield must be
at least 500 V according to IEC/EN 60079-14.
Use separation walls or protective covers to preserve the required
separation distances.
Ensure that the separation walls are correctly fitted and are in the correct
mounting position.
Observe the grounding requirements for type of protection Ex i according
to IEC/EN 60079‑14.
