Fitting on a top−hat rail
Proceed as follows when fitting the SFC−DC onto a top−hat rail:
1. Make sure that the fastening surface can support the
weight of the SFC−DC.
2. Fit a top−hat rail
(mounting rail EN 50022 35x7.5 or 35x15).
3. Maintain a max. distance of 3.3 mm between the housing
web and the top−hat rail:
·
if possible, use a part of the top−hat rail where there
are no fastening screws.
·
if a screw connection is necessary under the SFC−DC:
Use M6 screw acc. to ISO−7380ULF, for example.
4. Hang the SFC−DC on the top−hat rail as follows:
·
first from below, pressing against the clamping el
ement, then
·
swing upwards against the top−hat rail.
When you let go, the clamping element presses the
SFC−DC into the upper groove.
