2.12 Disposal
When disposing of the device, please comply with all relevant
requirements and regulations applicable in your country.
3. PROPER USE
The device is exclusively designed as a built-in device for conveying
air according to its technical data.
Note
;
The motor satisfies the requirements of category II 2G Ex d e ib IIB
T3 Gb. Devices of this category are intended for use in areas in
which the occasional occurrence of an explosive atmosphere of air,
gases and vapours or mists is to be expected (category 2G). The
device-related explosion protection measures of this category must
provide the required degree of safety even in the event of frequent
system malfunctions or fault statuses normally to be taken into
consideration (foreseeable faults). This involves assessment of the
individual risks of the system as a whole and implementation of the
necessary explosion protection measures.
Any other usage above and beyond this does not conform with the
intended purpose and constitutes misuse of the device.
Customer equipment must be capable of withstanding the mechanical
and thermal stresses that can arise from this product. This applies for the
entire service life of the equipment in which this product is installed.
When used in the intended manner, explosion-proof motors cannot ignite
explosive gases or vapours.
The manufacturer who installs ebm-papst devices is responsible for
ensuring operation in accordance with the intended use, operational
safety, proper installation, and EMC properties when installed.
The fan is designed for 40,000 hours of operation and must then be
replaced.
ebm-papst accepts no liability for subsequent modifications to the fan.
Proper use also includes:
●
Use the device in power systems with earthed neutral (TN/TT power
systems) only.
●
Conveying of air at an ambient air pressure of 750 mbar to 1050 mbar.
●
Using the device within the permitted ambient temperature range; see
chapter 4.2 Nominal data and chapter 4.5 Transport and storage
conditions.
●
Device protected against weather effects at the installation location.
●
Operating the device with all protective devices.
●
Using the device only in Zones 1 and 2 with explosion subcategories
IIA and IIB and temperature classes T1 to T3.
●
Using the device only in stationary systems.
●
Using the device only in resonance-free speed ranges to avoid spark
formation.
●
Punctual, complete performance of all maintenance; see chapter 7.3
Maintenance interval.
●
Observance of the operating instructions.
Improper use
Using the device in the following ways is particularly prohibited and
may cause hazards:
●
Operating the device with an imbalance, e.g. caused by dirt deposits
or icing.
●
Moving air that contains abrasive particles.
●
Conveying of highly corrosive air, such as salt spray mist. This does
not apply to devices designed for use in a salt-laden atmosphere and
accordingly protected. The same applies to all other corrosive
substances.
●
Moving solids content in flow medium.
●
Conveying of air with a high dust pollution level, e.g. extraction of
sawdust, flour dust etc.
●
Conveying of air containing iron and rust particles, e.g. use of the
device in a welding shop.
●
Operation (also when stopped) with external vibrations.
●
Operation in unstable flow conditions (vibration).
●
Operation with severe contamination (see maintenance instructions).
●
Installation and operation of the device with exposure to weather
effects.
●
Using the device as a safety component or for taking on safety-
related functions.
●
Operation in medical equipment with a life-sustaining or life-support
function.
●
Operation with vibration transmitted to the fan from external machines
or attachments.
●
Operation with externally induced mechanical loads that are in
excess of the permitted level.
●
Opening of the terminal box during operation, see chapter 4.1 Product
drawing.
●
Painting the fan.
●
Standing or walking on the fan or ventilation unit.
●
Operation with completely or partially disassembled, manipulated or
inadequate protective devices.
●
Connections (e.g. screws) coming loose during operation.
●
Upstream connection of frequency converters.
●
Connection of attachments to the rotor housing.
●
Flow medium and ambient conditions not conforming to those of Ex
marking.
●
In addition, all application options that are not listed under proper use.
DANGER
Potential dangers in the event of non-compliance include
personal injury and property damage due to shaft
breakage, fatigue failure, reduced bearing service life or
explosions caused by elevated surface temperatures or
spark formation.
