1.9 Noise emission

The noise generated by a blower is not constant throughout
the performance range. For details of noise emission levels,
please refer to the table on page 21.
EN
In some cases, sound insulation may be necessary (it is rec-
ommended that emission levels be measured by the opera-
tor). Sound insulation must be provided by the operator to
avoid exceeding the statutory maximum levels at the work-
place and in the immediate vicinity of the blower.
Acoustic insulation of any type must never result in an in-
crease in the risk of explosion and you have to ensure,
e.g. that the maximum permissible ambient temperature of
+40 °C (blower) is not exceeded.

1.10 Obligations of the owner

The owner of an installation or machine is required to oper-
ate the equipment in accordance with EC directive 99/92/EC
(ATEX 137) and the applicable national regulations enforcing
the directive; for example, the directive requires that the risks
etc. be described in an explosion protection document.
The measures to be taken in the case of an ignition/ex-
plosion or any other serious incident are as follows:
If a fi re, defl agration or explosion has occurred
in the vicinity of or inside the unit, then the unit
must not be operated further regardless of the
cause of the explosion. In this case, as in the
event of other serious incidents, the equipment
must be made accessible / sent to Elektror for im-
mediate examination.
2 INFORMATION ON TRANSPORTA-
TION AND HANDLING OF THE MACHINE

2.1 Transportation and handling

• Prior to installation and putting into service, check all parts
for transit damage. A damaged blower is a potential safety
hazard and, therefore, should not be put into service.
• Do not store the blower unprotected in the open
(protect against moisture).
• Attach hoist securely. Only use hoists and load suspensi-
on devices with suffi cient load-carrying capacity. Secure
14
the route of transportation.
3 INFORMATION ON COMMISSIONING
THE MACHINE

3.1 Basic information

• Prior to the fi rst start-up and before any other start-up, the
proper operating status of the unit must be inspected.
Units that, for example, are found to be defective upon
delivery or during installation must not be operated.
• Set-up, installation, operation and maintenance must only
be performed by properly trained and qualifi ed specialists.
Operation following incorrect installation, maintenance or
unapproved replacement of components constitutes non-
designated use and renders the warranty void. The resul-
tant risk shall be borne solely by the customer or owner.
Note!
Reliable protection against incursion by foreign
matter, rust, airborne rust and other iron oxides is
provided.

3.2 Installation and assembly

• Install the blower so it is protected against weather and
sun exposure. Refer also to the information on installation
under 1.1, Designated use .
• During set-up, installation and subsequent operation,
never expose the equipment to vibratory or impact loads.
Permissible vibrational load on blower: refer to ISO 14694,
BV-3.
• Standard blowers with base:
Bolt securely to a level and fi rm surface at the place
of use, making sure that the surface has adequate load-
bearing capacity and avoiding vibration transmission or
vibrational load.
• For safety reasons, explosion-protected HRD FU
blowers cannot be set up or installed without a base.
• Cover the open intake and/or a discharge side connection
with wire guards compliant with DIN EN ISO 13857.
• Ensure adequate motor ventilation.
• Permissible ambient temperatures:
See 1.1 – Designated use.
• Special information for units suitable for, or even
designated for, FC operation: See 3.3.1 to 3.3.4.

3.3 Electrical connection

Note!
The work described in this section may only be
performed by a qualifi ed electrician. The dimen-
sioning and selection of connecting lines, includ-
ing the connection of the motor, must be made
according to the circuit diagram in the junction
box and the relevant local regulations.
• Design of the electrical installations in accordance
with EN 60079-14.
• Complete equipotential bonding must be achieved; i.e.
suffi cient and proper earthing of all electrically conducting
parts.
• Check that the mains voltage matches the specifi cation
on the nameplate.
• The drive motors used are exclusively explosion-protected
three-phase current motors.
• The safety earth terminal can be found in the terminal box.
• For further information about EMC compliant installation
and assembly, refer to the operating and assembly inst-
ructions issued by the frequency converter manufacturer.
• A PTC-resistor sensor integrated in the motor indepen-
dently of the version must be connected and evaluated
corresponding to the specifi cations of the motor manufac-
turer.
• For special information on the FC use, see 3.3.1 to 3.3.4
3.3.1 Special features when operating ATEX blowers at
the frequency converter
Note:
Only motors with pressure-proof encapsulation
must be operated at the frequency converter,
marked EEx de II2GD T4 135 °C!
For ATEX units suitable for frequency converter operation,
the temperature sensor (PTC-resistor sensor) built into the
motor must be connected to a monitoring device certifi ed for
ATEX applications and evaluated.
Only trip relays meeting the criteria set forth in IEC 61508,
and which are capable of assuming a safety position in case
of error (fail safe), are suitable.
