Remember to set RS485 Link positions (LK1 and LK2), and if required, remove the wire link to enablethe connection of a Redundant Power Supply before installing, see Figure 2.3 parts reference.1. Check that the mounting panel is no thicker than 25mm (typically for wood or plastic) and no thinner than 2mm(for steel).2. In the mounting panel, cut an aperture 99mm x 138mm (+ 1mm). If more than one T820 is to be mounted in thepanel, the recommended minimum spacings are as shown below.3. From the front side of the mounting panel, insert the instrument (rear end first) through the aperture.4. Support the rear of the T820 so that the seal is flat against the front of the mounting panel.5. Insert two panel clamps into the opposing pair of rectangular apertures at the sides of the case.6. Tighten the screws of the clamps sufficiently to hold the T820 firmly in position.Note. When mounted directly in a panel the unit is rated IP66 front of panel, and IP20, rear of panel.X*Panel cutout99mm x 138mm(+ 1mm)Top View99mmY*104mm6mm43mmRear cover fixing screws(4, 1 per corner)Front View144mm68mm115mm138mmMaximum panel thickness= 22mmView on right-hand sideCase clampingMinimum recommended inter-unit spacingClamp Position X* Y*Left and right 14 mm 7.5 mmFigure 2.3.1Mounting the T820 to a PanelChapter 2Page 2 - 6HA029131Issue 3 Feb 08
