Wiring
Consider temperature for external cables!
Cables may experience temperature increase due to system heat dissipation. Thus the cabling speci-
fication must be chosen 5 °C above ambient temperature!
Separate insulation areas!
The system is specified for SELV/PELV environment. Devices, which are attached to the system must
meet theses specifications. Installation and cable routing other than SELV/PELV specification must
be separated from the system’s equipment!

FLEX bus couplers have an integrated power module. Terminals with spring clamp technol-
ogy are used for wiring. The spring clamp technology allows quick and easy connection of your sig-
