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 (EN 50110, IEC 60364-1)have been
checked, the fan is out of range (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. Check the system for resonances. If they lead to unacceptably high vibrations on
the fan, the system must not be started up.
5. 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/im-
peller unit checked by an expert and rebalanced if necessary before continuous
operation is permitted.
