4 Electrical connection

The unit must be connected by a qualified electrician�

The national and international regulations for the installation of electrical

equipment must be adhered to�

► Disconnect power�

► Connect the unit as follows:

Core colours of ifm sockets:

1 = BN (brown), 3 = BU (blue), 4 = BK (black)

5 Operating and display elements

1: Operation display

• The green LEDs indicate the current flow (the LEDs 0 to 9 represent the range between

no flow and maximum flow)�

• A lighting LED indicates the position of the switch point (orange = output closed, red =

output open)�

2, 3: Setting buttons for adjustment and configuration
