;
We recommend storing the device for no longer than one year in
order to guarantee trouble-free operation and the longest possible
service life.
;
Even devices explicitly intended for outdoor use are to be stored as
described prior to commissioning.
;
Maintain the storage temperature, see
Chapter 4.5 Transport and storage conditions.
DANGER
Danger of explosion, ingress of dirt and moisture into
the motor
The degree of protection decreases.
→ Store the device in a completely assembled state only
(cable gland and terminal box cover are sealed)
2.12 Disposal
Comply with all relevant local requirements and regulations when
disposing of the device.
3. INTENDED 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 db eb ib
IIB T3 Gb. Devices of this category are intended for use in areas
where an explosive atmosphere of air, gases and vapors or mist is
likely to occur (category 2G). Even in the case of frequent system
malfunctions or fault conditions that usually must be taken into account
(foreseeable malfunctions), the device-related explosion protection
measures of this category must provide the required level of safety.
The individual risks of the complete system are to be evaluated and
the necessary explosion protection measures are to be taken into
account.
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 vapors.
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; after that period, it must
be replaced.
ebm-papst accepts no liability for subsequent modifications to the fan.
Intended use also includes
●
Using the device only in power systems with grounded neutral (TN/
TT power systems).
●
Conveying air at an ambient air pressure between 750 mbar and
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.
●
The device is to be protected against exposure to weather at the
installation site.
●
Operating the device with all protective devices.
●
Using the device only in Zones 1 and 2 with Ex categories IIA and
IIB and temperature classes T1 to T3.
●
Using the device only in stationary systems.
●
Using the device only in speed ranges without resonance to avoid
sparking.
●
Punctual, complete performance of all maintenance; see Chapter 7.3
Maintenance interval.
●
Following the operating instructions.
Improper use
In particular, operating the device in the following ways is prohibited and
could be hazardous:
●
Operating the device in an unbalanced state, e.g. due to dirt deposits
or ice formation.
●
Conveying of gas atmosphere above upper explosive limit.
●
Conveying air that contains abrasive particles.
●
Conveying highly corrosive air, e.g. salt spray. Devices that are
designed for use with salty air and are protected appropriately
constitute an exception. The same applies to all other corrosive
substances.
●
Conveying solids in the flow medium.
●
Conveying air with high dust exposure, e.g. sawdust, flour dust
suction system or the like.
●
Conveying air that contains iron and rust particles, e.g. using the
device in a welding shop.
●
Operation (also when stopped) with external vibrations.
●
Operation in unstable airflow conditions (oscillation).
●
Operation in very dirty conditions (see maintenance instructions).
●
Installation and operation of the device exposed to weather.
●
Using the device as a safety component or to perform safety-related
functions.
●
Operation in medical equipment with a life-sustaining or life-support
function.
●
Operation with vibrations that are transferred to the fan from external
machines or attachments.
●
Operation with mechanical loads which are introduced from external
sources and are higher than permitted.
●
Opening 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 or manipulated or
inadequate protective devices.
●
Connections (e.g. screws) coming loose during operation.
●
Upstream connection of variable frequency drives.
●
Connecting attachments to the rotor bell.
●
Flow medium and ambient conditions that do not correspond to the Ex
marking.
●
In addition, all applications not listed among the intended uses.
