Installation
4.1
Mounting
The product is fixed with the four fixing points located at the corners of the product. M5 or M6
screws are used for the fixation of the product. The screws are tightened with min. 3.0 Nm (fixing
screw ISO 898/1, quality class 8.8).
NOTICE
All four specified fixing points must be used for fixing. The installation surface
should be flat to have all fixing points connected to the surface.
NOTE
For indoor installation consider additional protection against dust to ensure proper
heat dissipation.
NOTE
For outdoor installation consider additional protection against sun radiation, dust
and dirt to optimize ambient temperature range.
NOTE
Unused connectors must be covered by a protective cap (delivered with
the product), tightened to the specified torque in order to fulfill the
specified ingress protection code.
4.2
Earth Connection
There are two earth connection points. At the AC connector there is the connection point for the
protective earthing conductor and at the grounding screw of the Ibex-RT-370 housing is the
connection point for the protective bonding conductor.
For a safe operation and proper protection against lightning, both earth contacts must be connected
to a solid ground. The grounding must be done always as a first step before connecting any other
external interfaces.
An M5 grounding screw at the housing is used for the protective bonding conductor. A short wire
with a cross section of at least 4 mm2 shall be used. The grounding wire is set below the rip-lock
washer. The nut is fixed for good reliable grounding contact. The tightening torque of the nut shall be
2.0 Nm.
