Auf besondere Vorsicht muß während des Ein- und Ausbaus des

Einheits geachtet werden.

Der Sicherheitsstandard der Anschlüsse fuer dieses Gerät sind wie folgt:

Anschlüsse bezeichnet mit PSTN und LEASE = TNV

Anschlüsse bezeichnet mit DTE = SELV

TNV (Telecoms Network Voltage - Spannung des

Telekommunikationsnetzwerks) ist ein Anschluss, der unter normalen

Umständen Telekommunikationssignale enthält .

SELV (Safety Extra Low Voltage - Extra Sicherheitsspannung) ist ein

weiterer Anschluss, der unter normalen Umständen und

Fehlerkonditionen entworfen und gesichert wurde, so dass die

Spannung zwischen zwei erreichbaren Teilen kein gefährliches Niveau

erreicht (42.2V max. oder 60V DC).

An den Anschlussbuchsen der Geräte dürfen nur die dafür

vorgesehenen Anschlüsse verwendet werden.
