Safety instructions
This chapter contains instructions to prevent personal injury and property damage. These instructions
do not lay claim to completeness. In case of questions and problems, please consult our company
technicians.
Information
Mounting, electrical connection, and start-up operation may only be carried out by an electrical
specialist in accordance with electrotechnical regulations (e.g. EN 50110 or EN 60204)!
Danger due to electric current
•
It is generally forbidden to carry out work on electrical live parts. Protection class of the device when
open is IP00! It is possible to touch hazardous voltages directly.
•
The safe isolation from the supply must be checked using a
two-pole
voltage detector.
•
The rotor is not protected against indirect contact neither by supplementary or reinforced insulation
nor by connection to safety-earth in accordance with EN 60204-1, therefore the motor/fan must be
installed so that it is not touchable.
•
When the motor runs independently due to air
fl
owing through or if it continues to run down after
being turned off, dangerous voltages of over 50 V can arise on the motor internal connections
through operation of the generator.
•
Even after disconnecting the mains voltage, life-threatening charges can appear between the
protective ground
“
PE
”
and the mains connection.
•
The protective earth is conducting high discharge currents (dependent on the switching frequency,
current-source voltage and motor capacity). Earthing in compliance with EN speci
fi
cations shall
therefore be observed even for testing and trial conditions (EN 50 178, Art. 5.2.11). Without
earthing, dangerous voltages can be present on the motor housing.
Waiting period at least 3 minutes!
•
Through use of capacitors, danger of death exists even after switching off the device through
directly touching the energized parts or due to parts that have become energized due to faults.
•
The controller housing may only be removed or opened when the power line has been switched off
and a period of three minutes has elapsed since switching it off.
Attention!
•
During commissioning, unexpected and hazardous conditions can arise in the entire installation due
to defective adjustments, defective components or incorrect electrical connections. Remove all
persons and objects from the hazardous area.
•
Before
fi
rst-time start-up, check the following:
1. Installation and electrical connection have been properly completed?
2. Has any leftover installation material and other foreign material been removed from the fan
area?
3. That safety devices -if necessary- are mounted (EN ISO 13857)?
4. The impeller is out of reach?
5. Are the condensation water drains holes open or respectively closed according to the suitable
installation position?
6. Connection data complies with the speci
fi
cations on the rating plate?
•
Start-up may only begin when all safety instructions have been veri
fi
ed and any hazards have been
ruled out.
–
Check for quiet, low vibration operation. Strong vibrations due to erratic operation (unbalanced),
e.g. caused by transportation damage or improper use, can lead to failure.
–
A-rated sound power levels of over 80 dB(A) are possible, see product catalogue.
–
Check for mechanical vibrations after installation into the system. If the tolerances according to
ISO 14694 are exceeded, it is possible to exclude certain speed ranges (see Motor Setup).
–
Check the direction of rotation (see rotation direction arrow on the fan blade, impeller base plate
or on the fan housing).
•
Maintenance work may only be carried out by suitably quali
fi
ed personnel.
"
Before working on the fan, this must be disconnected from the power supply and secured against
switching back on!
"
No maintenance work at running fan!
"
Wear safety shoes and gloves for handling!
"
Please observe the safety regulations and the worker
´
s protection rules by all maintenance and
service work (EN 50 110, IEC 364).
