Mechanical installation in a control panel
For installation in the control cabinet door or the control panel, a cut-out of 137mm x 82mm (tolerance +/- 1mm)
must be made. The sealed unit must be inserted in the pre-processed cabinet panel. There are 6 screws (M3 x
7mm) for securing the unit to the interior of the control panel. The ParameterBox is now mounted securely on
the switching cabinet door and has maximum protection class IP66 on the front side, if mounted correctly.
The electrical connection of the ParameterBox SK PAR-2E can take place in the installation variant via the
