WIRING
Mount and wire the S2000-К as shown in Figure 2. Wires are connected to the S2000-K by means of
the screw terminal blocks.
Figure 2. S2000-K Wiring Diagram
Connecting the Orion RS-485 Interface Bus
To connect the S2000-K to the network controller via the RS-485 interface bus connect A and B ter-
minals of the ХТ1.2 terminal block to the A and B wires of the RS-485 bus correspondently. If the
S2000-K is the first or the last device within the RS-485 bus, add the supplied termination resistor
620 W across the А and В terminals of the ХТ1.2.
WARNING! If the RS-485 interface bus is quite long (more than 1000 meters), use twisted-pair ca-
bling to connect the devices. The resistance value of each RS-485 interface line (A or B) measured
between the network controller and the most distant device MUST NOT exceed 200 W.
Connecting the Power Supply
Connect a direct power supply 10÷28 V @ 100 mА to the ХТ1.1 terminals of the S2000-К as shown in
Figure 2 coupling the 0 V circuit of the S2000-К with the 0 V circuit of the network controller. If both
the devices are powered by the same power supply, coupling can be omitted.
