Electrical Connections
Note! All electrical installations must be made by authorized installer and in accordance with
regulations in force.
The Combini EC (pos 1, fig. 11) is controlled from a wall mounted 3 step speed regulator (pos 2, fig.11
below). A separate 3-step speed regulator is used and a 3-wire cable needs to be connected to the speed
regulator (fig.12 below). At the end of that cable a 4 pole male plug, type Ensto NAC41SH.W can be
applied in order to fit the corresponding connector (Ensto NAC42SH.W) on the Combini EC. Make sure
that the cable colours correspond to each other when the two connectors are joined.
Check the enclosed wiring diagram for more detailed information
