6 Start-up
6.1 Prerequisites for commissioning
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.
•
Do not start the fan until all safety instructions (DIN EN 50110, IEC 364) have been checked, the
fan is out of range (DIN EN ISO 13857) and danger can be ruled out.
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. Connection data complies with the speci
fi cations on the rating plate?
During start-up check the following:
1. Check the direction of rotation ( rotation direction arrow on the fan blade, impeller base plate or
support plates on suction side or rating plate).
2. 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.
3. A-rated sound power levels of over 80 dB(A) are possible, see product catalogue.
4. Fans from ZIEHL-ABEGG SE are delivered balanced in accordance with ISO 1940-1 for the
appropriate fan category in accordance with ISO 14694. Check the fan for mechanical vibrations
after installation. If the limit values of the corresponding fan category are exceeded in start-up,
you must have the motor/impeller unit checked by an expert and rebalanced if necessary before
continuous operation is permitted.
