absorb the relative movements of the section that the expansion unit is installed in.Expansion units must be used in the following cases:  The run is made up of straight sections longer than 30 m: the expansion unit absorbs length variationsof the run components occurring due to changes in temperature. The run passes through an expansion joint between two buildings: the expansion unit absorbs theforces due to the movement of the two buildings relative to each other.ProcedureThe procedure for installing expansion units is the same as the procedure for installing run components on horizontal supports (seepage27). The procedure is described in the instruction sheet AAV32038 available on the Schneider Electric website.Expansion Units on Long RunsIf the run length is greater than 30 m, you must provide for expansion units and appropriate means of anchoring.
