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.

LONWORKS Network

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

ONWORKS 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

ONWORKS 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

ONWORKS network screw terminals on the

SmartServer.
