4 .12 Connecting duct (Aluflex ducting)
Observe bending radius R > DN of the connection cable!
Connect steel/steelflex ducting (DN 80) to discharge openings and attach with screw (max. L = 20 mm, position 64
mm) incl. flexible tape (Fig.49 and 50).

The connection cable must be stored so that water cannot penetrate along the cable in case of water expo-
sure . The cable must not pass over sharp edges!
The electrical connection must be isolated from the mains power supply until final assembly!
The accessory parts and installation and operating instructions must be placed in the ELS casing and closed
away with the cleaning protection cover when assembly is complete!
EMC regulation/standard
Important note for the electromagnetic compatibility
The interference resistance according to DIN EN 55014-2 depends on impulse form and energy share 1000 V to 4000
V. In case of operation with fluorescent tubes, switching power supplies, electronically controlled halogen lamps, etc.,
these values may be exceeded. In this case, additional anti-interference measures on-site are required (L, C or RC
modules, protective diodes, varistors).
