•   Firmly screw down the feet on blowers at the place of use onto 

 a suitable 

fi

 rm level load-bearing base free from transmis-

  sion of vibratory or shock loads.
•  Other standards and regulations must be observed

  depending on the application.
•  Blower feet and consoles must be designed only for the

  respective blower’s own weight.
•  Cover the open air intake and discharge with protective

  grilles according to DIN EN ISO 13857.
•  Ensure that the motor has adequate ventilation.

  Permitted ambient temperatures with:

  Standard model with Elektror motor and a rated

  frequency of 50 Hz or 60 Hz:

  • Ambient temperature -20°C to +60°C

Note!

The rated e

ffi

  ciencies and the e

ffi

  ciency classes 

of the motors are given as per IEC 60034-2-1 for 

operation at an ambient temperature of 25°C.

As per IEC 60038 Elektror motors are generally 

designed for an extended voltage range of ±10%. 

However, the stated e

ffi

  ciency relates to the rated 

voltage, i.e., the extended tolerance is not taken 

into account.

Special voltages, multi-voltage motors, models suitable for 

frequency converters, FUK models, devices with UL approv-

al, devices with Aircontrol and other motor makes:
  • Ambient temperature -20°C to +40°C
  • Voltage tolerance ±5% (For exceptions, see „4.2 Fre-

quency converter operation“)
•  The drive motor ventilation system must not be a

ff

 ected by 

  the installation situation.

3.3 Electrical connection

Note!

The work described in this section may only be 

performed by a quali

fi

 ed electrician. Connect the 

appliance as per the circuit diagram in the termi-

nal box and in accordance with the relevant local 

requirements.

Three-phase or single-phase a.c. motors are used as drive 

motors. In the equipment identi

fi

 ers, the letter D denotes 

three-phase (3~) and E denotes single-phase (1~).
•  The drive motor must be protected by a motor circuit break

  er (not applicable for units powered by frequency convert-

  er). With units powered by frequency converter, the exist-

  ing temperature sensor (PTC thermistor detector) or 

  temperature monitor (break contact) is to be connected to 

  the converter and evaluated.
•  Checking that the supply voltage matches the details on 

  the rating plate.
•  The safety earth terminal can be found in the terminal box.

Note!

The following information should also be ob-

served when operating the drive motor with a 

frequency converter:
• Only motors must be used on the frequency 

converter that are marked on the rating plate with 

the option “/FU”, “suitable for use with a frequen-

cy converter” or that were ordered and con

fi

 rmed 

as “suitable for use with a frequency converter”.
• The frequency converter supply voltage must 

only be a maximum of 400 V without the motor 

fi

 lter. Appropriate measures such as a motor 

fi

 lter 

to protect the motor must be installed on the 

motor terminals with higher frequency converter 

supply voltages, longer lines and/or if the pulse 

voltages are exceeded (max. 1000 Vpk for drive 

motors up to 0.75 kW, maximum 1300 Vpk for 

drive motors larger than 0.75 kW)  Please contact 

the converter supplier in this case. If a motor 

fi

 lter 

is included in the delivery, this must be installed 

between the converter and the motor. Please 

ensure that there is su

ffi

  cient space in the switch 

cabinet and take into account the installation and 

assembly requirements in the operating instruc-

tions of the frequency converter/motor 

fi

 lter 

manufacturer.
• The maximum cable length between the mo-

tor and switch cabinet frequency converter (e.g. 

Lenze Vector, Omron MX2 and Omron RX) must 

not exceed 20 m. Maximum cable lengths of up to 

3 m are permitted with Kostal INVEOR frequency 

converters installed close to the motor and up to 

10 m with Lenze MOTEC frequency converters. 

Further information on wall mounting close to the 

motor can be found in the original operating and 

assembly instructions of the respective frequen-

cy converter manufacturer. The electrical con-

necting cables between the motor and frequency 

converter in the above cases must be suitable 

shielded cables, laid using the shortest route and 

without clamping and plug-in connections and 

connected correctly at both sides. 
• The shielding braid in the connecting cables 

must be connected fully, continuously and on 

both sides, i.e. to the frequency converter and 

motor, and at low resistance and permanently to 

protective earthing systems or the main earthing
