the enclosed wiring diagrams.
– The relevant standards, safety regulations (e.g. DIN VDE 0100) and the technical connection regulations of the ener-
gy supply companies must be observed!
– An all-pole mains switch/isolator, with at least a 3 mm contact opening (VDE 0700 T1 7.12.2 / EN 60335-1) is man-
datory!
– The network configuration, voltage and frequency must be consistent with the information on the type plate.

impossible. The cable must never be placed over sharp edges.
– The units are protection type IPX5 (jet water-proof ) and correspond to protection class II.
– The electrical connection is carried out at the connection terminals in the casing. The corresponding wiring diagram
for the respective fan type and casing must be observed.
