Mounting the sample station (without SM331)
Description
Bolt together the rail to the ground or underground (screw
size: M6) so that at least 40 mm space remains above and
below the rail
If the base is a grounded sheet metal or a grounded
mounting plate, ensure that the rail and the base are con-
nected together with low resistance.
Connect the rail with the protective ground wire. A M6 bolt
is available for this purpose.
Mounting the power supply
• Hang the power supply to the top end of the rail
•
and tighten it to the rail underneath
