WIRING
• Deactivate the 24 Vac/dc power supply until all connections are made to the device to prevent
electrical shock or equipment damage.
• Follow proper electrostatic discharge (ESD) handling procedures when installing the device or
equipment damage may occur.
• Use 22 AWG wiring for all connections and do not locate the device wires in the same conduit with
wiring used to supply inductive loads such as motors.
• Make all connections in accordance with national and local codes.
Connect the 24 Vac/dc power supply to the terminals labeled PWR +(power) and - (common) as
shown in Figure 9. This device has a half-wave type power supply so use caution when wiring multiple
devices so that the circuit ground point is the same on all devices and the controller. Use caution if
24 Vac power is used and one side of the transformer is earth-grounded. In general, the transformer
should NOT be connected to earth ground when using devices with RS-485 network connections.
The device is reverse voltage protected and will not operate if connected backwards. Figure 10 shows
network connections. For end of Line (EOL) device place termination resister jumper in ON position, for
all other devices, place jumper in OFF position.
