2 Safety information
Danger
• Before maintenance, service or repair cut the power supply (all-pole breaker) and the impeller to stop.
• Mounted safety equipment must not be removed, bypassed or be disabled!
• Cleaning with a damp cloth when the fan is energized can cause electric shock!
The installation instructions are part of the product and should be stored so that it is always available. The manufacturer
of the system or the plant is responsible for the installation and that safety instructions are in harmony with the
requirements.
EX 140A/180A are certified according to Directive 2014/34/EU (ATEX). Fan Category for fans is BV3 quality grade G6.3
according to ISO 14694. The motor rating plate (A, figure 1) shows data for the motor and does not apply for the com-
plete fan. The fan rating plate shows data for the complete fan (B, figure 1). The field of explosion protection is stated
on the fan rating plate (for example Ex de IIC T4). The fan fulfils the requirement for zone 1 but does not separate zones.
Fan may be used in explosive environments for the transport of gas, but not the transport of hot fumes.
The fan is designed for transport of air or explosive atmospheres in Zone 1 and Zone 2. Transport of solids, shares of
solids or mixtures of dust/air is not allowed. The transported air must not corrode the fan housing, fan blades or motor
(aluminium and steel). Rust particles may not occur in the airflow.
Resonance vibrations can occur due to mounted components and should be checked during commissioning.
The fans must not be installed outdoors.

Installation, electrical connection and commissioning may only be performed by qualified personnel and in accordance
with the requirements and regulations for electrical installations in areas with explosive atmospheres.
Installation, inspection and maintenance in accordance with EN 60079-14/-17 meets the requirements. Fan should be
installed and protected against foreign objects that come in contact with moving parts and may cause sparks.
No moving parts should be accessible after installation (EN ISO 13857).
Inspection and cleaning should be done regularly, cleaning of deposits will prevent imbalance of the impeller. Make
sure that all the details are correctly reassembled after inspection/cleaning (see chapter 8).
Protective earth (PE) must be connected, the external ground wire connection is placed on the motor (figure 1). Electri-
cal connections must be made according to the wiring diagram. When the fan is controlled the current can increase at
regulated voltage, the power must never exceed the rated power, see table 1. Data provided on the rating plate applies
to air with density of 1.2 kg/m3.

Motors are equipped with PTC resistors in triple execution. More than two PTC resistor chains may not be connected in
series, as this can lead to indefinite suspension. Max. test voltage of PTC resistors are 2.5 V.
Inspection and maintenance of the temperature monitoring unit shall be made according to instructions and according
to a time interval specified in the certificate and instruction manual of the temperature monitoring device.
Note:
Speed control using frequency inverter is not permitted. It is only permitted to use transformer-based
controls for speed control. The fan current/power must not exceed the current/power specified on the fan
rating plate at rated voltage. By increasing the static back pressure the fan can be throttled up to a lower
current/power if the speed control is not in use.

3 Transport and storage
The fan is packed at the factory to withstand normal handling during transit. Avoid blows and shock loads. Store the fan
in a dry, dust-free place without damaging vibrations (v eff <0.2 mm/s) to avoid bearing damage. Avoid long storage
periods (we recommend max.1 year). Before installing the fan, check the motor bearings for noise (spin the impeller
carefully by hand).
Caution
Do not lift the fan in any cable, junction box or the impeller.
