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.
6.2 During start-up check the following
Observe the following points before the initial start-up:
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. Have all objects (tools, etc.) been removed from the air
fl
ow?
4. That safety devices -if necessary- are mounted (EN ISO 13857)?
5. The impeller is out of reach?
6. Are the condensation water drains holes (as far as available) open or respectively
closed according to the suitable installation position?
7. Continuous potential equalisation must exist.
8. Connection data complies with the speci
fi
cations on the rating plate?
9. Protective conductor and external earthing conductor have been connected.
10. Thermistor and triggering device have been properly installed and are operational?
11. Are all conductive attachments and accessories earthed?
12. If motor impeller units are stored or operated after long periods without use, or if
they have been exposed to condensation over a longer period, the insulation
resistance of the motor winding must be measured before start-up (or restarting). If
the value is less than or equal to 1.5 M
Ω
the motor winding must be dried.
