2. INSTALLATION INSTRUCTIONS
The UNI-2 is a calculator indicator. It can be combined with four sensors. It can either be installed on a turbine
or with an enclosure extension.
An O-Ring provides sealing between the turbine or the enclosure extension. Ensure that the ring is in
place and has been lubricated before tightening the screw. The seal must be at least IP20.
The sensors are connected to the UNI-2 either inside the enclosure or through cable glands and terminal
blocks.
Maximum cable length from UNI-2 models to temperature sensors, liquid sensors and L7 to L9 case doesn’t
exceed 10 meters.
    2.1. Variants:
The variant marking of the UNI-2 is readable inside the enclosure on a label plate comprising a letter and a
number defining the variant used.
