3. Build up clamp assembly 5 . Fully tighten the inner screws whilst leaving the outer (rear facing) ones slack. Slide the clamp assembly just over the channels of the first two cases and tighten the lowest outer screw. 4. Fit four spacers 2 above the relays, one to each joining strip and two to the clamp assembly. 5. Slide the next pair of relays into position and secure to the mounting strip. Fit another four spacers. Repeat the procedure until all relays are firmly positioned.

Note 3
Where blanking plates GJ0108 are used, they should be positioned between relays, not at a tier end.
When it is required to seal the gaps between cases, a black self adhesive foam strip is available in 1 metre lengths. Part No. YH 5513 521
Note 2 Rear plates are used in pairs clipping back to back into the grooves of the joining strip GJ2021 and clamp assembly GJ0222.
Semi-projecting Mountings A range of collars is available for this purpose. Details are available from the Contracts Department. If it is required to mount a Midos Assembly on a panel complying with IBS EN60529 IP42, a sealing ring selected from the following table should be used in addition to the self adhesive foam strip.
