5 Installation

Before installing and removing the unit: make sure that no pressure is 

applied to the system

 

Insert the unit in a G¼ process connection

 

Tighten firmly

6 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

Voltage supply to EN 50178, SELV, PELV 

For the scope of validity cULus:

The unit shall be supplied from an isolating source and protected by an 

overcurrent device The „limited voltage“ requirements according to UL508 

must be complied with

 

Disconnect power

 

Connect the unit as follows:

Pin 1

Ub+

Pin 3

Ub-

Pin 4 (OUT1)

Binary switching output pressure monitoring

Pin 2 (OUT2)

Analogue output for system pressure

Core colours of ifm sockets:

1 = BN (brown), 2 = WH (white), 3 = BU (blue), 4 = BK (black)
