First the cable gland must be loosened. Then you have to feed the load cell cable through the cable gland
unless the shrink tube is fully disappeared in the box.
Afterwards the wires can get connected as follows (see also fig.2)
Cable coulour Description Terminal no., example
yellow = Cable shield First ground screw
(if applicable, blue)* = Sense + 1*
green = Excitation + (Input +) 2*
white = Signal + (Output +) 3
red = Signal – (Output –) 4
black = Excitation – (Input –) 5**
(if applicable, brown)* = Sense – 6**
* at load cells with 4-wire technology terminal no.1 and no.2 must get connected
** at load cells with 4-wire technology terminal no.5 and no.6 must get connected
