CHAPTER 2 o CONNECTING POWER AND SURGE PROTECTION
26
Connect a -DC conductor (usually a black wire) to either of the - screw 2
terminals on the boom of the Click! 201/202.
Wiring DC Power Out of the Click! 201/202Figure 2.7 –
Note
Do not use the screw terminal marked DCOK; it provides only 20 mA and
should be used only for monitoring the power supply.
The screw terminal connectors on the top and boom of the module are
removable to simplify wiring and are red-keyed, allowing the connector to plug
into only one correct jack.
Connecting DC Power
To power the sensor, 10-30 VDC needs to be connected to the Click! 200 in the pole-
mount cabinet. Additionally, if there is a main trac cabinet connected by a
homerun cable, you will need to connect DC power to the Click! 200 in that cabinet.
In the Pole-Mount Cabinet
Whether DC voltage comes from a homerun cable or from a Click! 201/202 within
the pole-mount cabinet, you can always wire the DC wires to the last screw
terminal on the UNPROTECTED side of the Click! 200 module. This will protect
your sensor from surges.
To wire DC power into the Click! 200:
Connect +DC (usually a red wire) to the +DC screw terminal. 1
Connect -DC (usually a black wire) to the GND screw terminal next to the 2
+DC terminal.
