Mounting
The SL serious of products
should be mounted on a
vertical surface via a stainless steel mounting plate (See
Fig 1A/1B/1C/1D/1E). The fixing holes on the mounting
plate are designed to fit M8 Allen Screw only. The
diameter is 9mm. Use of stainless steel fastener is
recommended by EX-TECH SAS.
