With unshielded power cables, place a grounded steel plate with a thickness of at least 1.6 mm
over the cables where they intersect with signal cables.

Ambient Temperature
The ambient temperature where signal and bus cables are laid must be within the range
–10 to 60 °C.
When using ER bus node units (ANR10S/ANR10D) to conform to the temperature specification,
the ambient temperature where the cables are laid must be within the range –20 to 70 °C.
Measures against EMI
As a rule, avoid laying the cables on the floor. However, lay them on the floor when there are
no ducts and no pits. In that case, it is required to cover them with shield plates or take other
measures to suit the EMC Directive.
