Thermally unfavorable arrangement of the TwinSAFE terminals
The following structure is rather unfavorable, since terminals with rather high waste heat are connected
directly to couplers or power supply terminals with high E-Bus load. The additional external heating of the
TwinSAFE terminals by the adjacent power supply units increases the internal terminal temperature, which
can lead to the maximum permissible temperature being exceeded. This leads to a diagnosis message
"overtemperature”.
