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.
•
A-rated sound power levels of over 80 dB(A) are possible, see product catalogue.
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 drain holes (as far as available) open or respectively closed according to the suitable
installation position?
6. Connection data complies with the speci
fi
cations on the rating plate?
During start-up check the following:
1. Check the direction of rotation (see 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. If resonance vibrations occur, it is possible to hide certain speed ranges (see Motor Setup).
4. Fans from ZIEHL-ABEGG SE are delivered balanced in accordance with DIN ISO 21940-11 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.
