UK
2.1 Certificates - Guidelines
If the unit is installed correctly and used for its intended purpose, it conforms to all ap-
plicable provisions and EU guidelines at its date of manufacture.
2.2 Receipt
The delivery contains the extension module:
KWL 45 EM
(Ref.no. 3012)
The shipment must be checked for damage and correctness immediately upon deli-
very. If there is any damage, promptly report the damage with the assistance of the
transport company. If complaints are not made within the agreed period, any claims
could be lost.
2.3 Storage
When storing for a prolonged time, the following steps are to be taken to avoid dama-
ging influences:
Protection by dry, airtight and dust-proof packaging (plastic bag with desiccant and hu-
midity indicators). The storage site must be vibration-free, water-tight and free from ex-
cessive temperature fluctuations. Damage caused during improper transportation, sto-
rage or commissioning is traceable and is not covered by warranty.
2.4 Area of application
The extension module KWL 45 EM can be connected to control KWL wall installation
units EcoVent.
Furthermore, for example, other fans in the Helios range can be current-monitored with

Supply
230 V~ 50/60 Hz
Frequency must be identical with the fan to be monitored.
Maximum load current of fan 2.0 A
Relay contact:
250 VAC 3A AC1 (ohmic load)
250 VAC 1A AC15 (AC relay, contactor)
24VDC 2A DC13 (DC relay, contactor)
Minimum load 1V/1 mA (gold contacts)
The relay is fitted with a gold contact. This enables the switching of very low
DC currents. Once AC currents are switched, the contact can then only be used for
this application.
Switching threshold adjustable via Poti, approx. 10 mA to approx. 400 mA +-5mA,
Setpoint strongly dependent on the fan to be monitored and its inductive / capacitive
load
