3.4 Functional earth (GND terminal)
The elmeg hybird 300 / elmeg hybird 600 requires a functional earth connection for safe operation. Hence, an
»earth line« should be located in the vicinity of the assembly site (a water line or heating line connected to the poten-
tial equalisation line, or the building installation's equipotential bonding strip). Connection to the elmeg hybird 300
should occur via a connecting line of at least 2.5 mm
2
.
Hinweis
If terminals are connected to the safety earth or service earth (e.g. USB or serial interfaces), the func-
tional earth connection should be as short as possible, as ground loops may otherwise ensue.
3.5 SD card
SD cards can not be formatted in the system.
The following data can be stored on the SD card:
• Audio files in "wave" format
• Music-on-hold files in "wave" format
• "Wave" files for voice applications
3.6 Reset
The elmeg hybird 300 / elmeg hybird 600 is rebooted by quickly pressing the key (ca. one second). Pressing the
key is equivalent to interrupting the power supply. Saved data are preserved, but all connections interrupted.
If you press the reset key for ca. 30-40 seconds, the elmeg hybird 300 / elmeg hybird 600 will execute a factory re-
set. This means that the elmeg hybird 300 / elmeg hybird 600 is returned to its ex works state. The boot configura-
tion is deleted and all passwords are reset. The reset is accomplished when the elmeg hybird 300 / elmeg hybird
600 returns to operating status after ca. 30 to 40 seconds, and the status LED returns to blinking.
