Sicherheitshinweis: Vorsicht Netzspannung!
Stellen Sie sicher, daß die Netzspannung ausgeschaltet wurde (Schalterstellung OFF),
ehe der Gehäusedeckel entfernt, an der Spannungsversorgung hantiert oder irgendeine
Netzverbindung mit dem SmartServer Gerät hergestellt wird.
AUF KEINEN FALL darf das SmartServer mit Netzspannungen ausserhalb des Bereichs
100/240V, -10% bis +30%, 50/60Hz±2.5Hz betrieben werden.
Avvertenza sulla Sicurezza e sull'Alta Tensione
Assicurarsi che la rete elettrica sia SPENTA prima di rimuovere il coperchio, maneggiare
i cavi di alimentazione, o connettere qualsiasi cavo al SmartServer.
NON connettere mai per nessun motivo il SmartServer a tensioni al di fuori del range
100/240VAC, da -10% a +30%, 50/60Hz +-2.5Hz.

The FT models of the SmartServer contain one set of screw terminals (17-18) that you can use to
connect the SmartServer to a TP/FT-10 L
ON W ORKS channel. The TP/FT-10 interface is
polarity-insensitive and requires connecting the twisted pair to terminals 17-18.
You can also use screw terminals 17–18 on the PL-20 model of the SmartServer with the external
coupling circuit to connect the SmartServer a single-phase or three-phase external coupler. This
enables you to operate the SmartServer on single-phase and three-phase PL-20 L
ON W ORKS networks.
In this case, the twisted pair interface is polarity-sensitive; therefore, you can connect terminal 18 on
the SmartServer (PLT+) to the positive terminal of the external coupler and terminal 17 on the
SmartServer (PLT-) to the ground terminal (low side) of the external coupler.
The length of the twisted pair connected to the FT models of the SmartServer must not exceed 1m in
order to provide flexibility in mounting the device in an enclosure. In addition, the SmartServer must
be installed at least 30cm away from electrically noisy devices.
The following figure illustrates the location of the L ON W ORKS network screw terminals on the
SmartServer.
