Where the earth rail is required to be positioned at a lower height and
to allow access to the IMB57 mounting screws, the straight earth-rail
bracket ERB57S can be inserted in the lower slot, but only after
insulating mounting blocks IMB57 are clamped to the DIN rail. This may
not be possible if, for example, trunking is fitted. In this case, fit offset
earth-rail bracket ERB57O (see figure 4.7) in the upper slot: the
mounting blocks can then be fitted in a restricted space with this bracket
already fitted.
