Terminal strips
4.4.1.
The terminal strips are located in the rear wall of the instrument. If provided on the side of the
switchgear, perform electrical connection according to the following terminal reference list (See also
circuit diagram on the top side of the instrument, numerical arrangement from right to left). Use fer-
rules of L=6 mm, max. 0.75 mm2 .The maximum permissible tightening torque is 0.4 Nm.
