Safety
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 must only be operated in the specified ambient temperature range and at the spec-
ified relative humidity without condensation.
Protection of the personnel and the plant is not ensured if the device is not used according to its
intended use.
The device is not suitable for isolating signals in power installations unless this is noted sepa-
rately in the corresponding datasheet.
1.8 Mounting/Installation
Prior to mounting, installation, and commissioning of the device you should make yourself
familiar with the device and carefully read the instruction manual.
The device may be installed in Zone 2.
The device has to be erected in such a way that corresponding to IEC 60079-15, a degree of
protection of at least IP54 according to IEC 60529 is achieved.
The device has to be erected in such a way that a pollution degree 2 or less according to
IEC 60664-1 is achieved if the device is connected to an intrinsically safe limited voltage
according to IEC 60079-11:2011.
The statement of conformity and certificate of compliance of the Fieldbus Power Hub must be
observed. It is especially important to pay attention to any special conditions for safe use that
are indicated.
Avoid electrostatic charges which could result in electrostatic discharges while installing, oper-
ating, or maintaining the device.
If the device has already been operated in general electrical installations, the device may sub-
sequently no longer be installed in electrical installations used in combination with hazardous
areas.
Observe the installation instructions according to IEC/EN 60079-14.
Connection or disconnection of energized non-intrinsically safe circuits is only permitted in the
absence of a hazardous atmosphere.
1.9 Operation, Maintenance, Repair
Only use operating elements in the absence of a potentially explosive atmosphere.
Only plug and pull the energized module in the absence of a potentially explosive atmosphere.
Connection or disconnection of energized non-intrinsically safe circuits is only permitted in the
absence of a potentially explosive atmosphere.
Observe IEC/EN 60079-17 for maintenance and inspection of associated apparatus.
The device must not be repaired, changed, or manipulated. In case of failure, always replace
the device with an original device.
1.10 Disposal
The device, built-in components, packaging, and any batteries contained within must be dis-
posed in compliance with the applicable laws and guidelines of the respective country.
