Danger due to electric current
•
It is generally forbidden to carry out work on electrical live parts!
•
Only remove the lid from the terminal compartment (available depending on the
model) with the line voltage switched o
ff
!
•
Opening of the base lid is prohibited. Loosening the safety screws will void the
guarantee!
–
Protection class of the device when complete open is IP00! It is possible to touch
hazardous voltages directly.
–
Through use of capacitors, danger of death exists even after switching o
ff
the
device!
•
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 o
ff
, dangerous voltages of over 50 V can arise on the motor
