5. PRE-INSTALLATION
Ow-RX does not ask for special pre-installation works, still it is necessary
to grant an adequate grounding for EMC compatibility and safety.
Section of grounding cable must be at least equal of greater than the
section of line cables. It is advisable to use a grounding cable with
section 2.5mm².
If cables are going to be positioned inside the wall, it is better that ducts
are already positioned, taking into account where the device will be
installed, taking care that cables exit in correspondence of the hole on
the lower side of the wall plate.
The Manufacturer can assist technically in the pre-installation phase,
but preparation works are a customer’s responsibility.
5.1 Mounting methods
NOTE:
This chapter is valid for Wall version. The user does not need to assess
the consistency of the wall for Stand version.
The installer is responsible for assessing the consistency of the wall.
The extraction load on each screw is 446 N (46 kg) for the wall version
standard assembly (3 mounting screws), 634 N (65 kg) for the wall
version "single stud" assembly (5 mounting screws).
For each type of wall use the appropriate mounting method complying
with the following specifications which guarantee a safety factor 4:
• Wooden uprights: self-threading screws 8x70 A 4.8 (provided with the
installation kit)
• Full or concrete bricks: screw anchors (provided with the installation
kit) in cast iron M8 or chemical screws WURTH (not provided)
• Hollow bricks: chemical screws (not provided).
A counter-plate must be used with walls with a lower resistance.
WARNING:
The Manufacturer is not responsible for any installations that do not
comply with the specifications stated above.
