Installation Refer to Safety information above. Installation, electrical connection and commissioning are only to be carried out by authorised personnel and in accordance with requirements and demands. Electrical connections are made according to the wiring diagram in the terminal box, markings on terminal blocks or on cable. All 3 phase fans are delivered from factory in 400V 3~ connection. Seal any empty cable glands with dummy plugs. The K-fan must be installed with the connection box at the top of the unit ± 90 degrees. If permanent installation is carried out using cables with diameter 12-14 mm, the entrance bush must be replaced (applies to type K, KV, RVF and KVK 125/160). To preserve IP44 the RS fans must not be mounted with the connection box/motor plate upwards (Fig.1).When installing KBT in high level of moisture (e.g. washing area), sufficient drainage to the fan is crucial. This is to prevent freezing damage to the fan in case of low temperatures.
