additional label.
On ATEX units with Ex eb motor, the thermal motor circuit-
breaker with PTC-resistor sensors for direct temperature
monitoring is permissible only in addition to the overload pro-
tection (upon request).
When using units for FU operation with an Ex db eb motor,
it is also essential to observe the information under 3.3.1. to
3.3.4.

1.11 Noise emission

The noises emitted by the blower are not constant over the
entire output range. Refer to the table on page 24 for the
noise levels emitted.
Sound insulation is required in certain unfavourable cases
(we recommend that the owner takes measurements). The
owner must provide sound insulation so that the maximum
values permitted by law are not exceeded at the workstations
around the blower.
Sound insulation of any kind must not lead to an inadmissible
increase in the ambient temperature on the drive motor to
over max. +40°C.
1.12 Speeds
Warning!
The maximum speed stamped on the motor rating
plate must never be exceeded in order to prevent
personal injury.
The blower is at risk of mechanical damage if the
speed is exceeded.
Each component on the blower has unique natural frequen-
cies. These can be induced by certain blower speeds, which
may result in resonance mode.
The blowers are designed in such a way that resonance does
not generally occur at a constant operating speed.
This may be induced in certain circumstances when the
speed is changed if the blower is operated on a frequency
converter. These circumstances are also infl uenced by the
customer's individual installation situation or ventilation con-
nection.
These natural frequencies must be excluded by parametris-
ing the frequency converter accordingly should they be pre-
sent within the speed range of the blower.

1.13 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:
Note!
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
immediate examination.

2 INFORMATION ON TRANSPORT,
HANDLNG AND STORAGE OF THE
MACHINE

2.1 Transport and Handling

• Check all parts for transport damage prior to the installa-
tion and start-up. A damaged blower represents an in-
creased safety risk and therefore must not be put into
operation.
• Do not store the blower unprotected outdoors (protect
against moisture).
• Fasten lifting gear securely. Only use lifting gear and load-
carrying equipment with suffi cient load-bearing capacity.
Secure transport routes.
Note!
The eye bolt on the motor must not be used to lift
the entire blower. This is used if the motor needs
to be (dis)assembled.
2.2 Storage
• Ensure that the air intake connection and pressure connec-
tion are closed.
• Store the blower
-> in its original packaging if possible
-> in a closed room
-> in a dry, dust-free and vibration-free area.
• Storage temperature range from -20°C to +60°C
• After a storage period of 6 months, the blower bearings
and/or motor bearings should be checked before they are
mounted in the blower.

HANDLING AND STORAGE OF THE
MACHINE
2.1 Transport and Handling
• Check all parts for transport damage prior to installation
and start-up. A damaged blower represents an increased
safety risk and therefore must not be put into operation.
• Do not store the blower unprotected outdoors (protect
against moisture).
• Fasten lifting gear securely. Only use lifting gear and load-
carrying equipment with suffi cient load-carrying capacity.
Secure transport routes.
Note!
The eyebolt on the motor must not be used to lift
the entire blower. This is used if the motor needs
to be (dis)assembled.
