Click 223 Dual-485 Surge
QUICK START GUIDE
1
Mount the device
The Click 223 mounts over a T-bus for power and communication:
1
If the Click 223 was shipped with the T-bus connector at-
tached, remove the connector from the module.
2
Snap the connector onto the DIN rail by positioning it over
the rail with the male connector pointing to the right. Hook
one arm over the edge of the DIN rail and press down on the
other arm until it snaps into place.
3
Connect the T-bus connector to the rest of the T-bus by slid-
ing them together until you hear them snap into place.
4
Mount the Click 223 onto the DIN rail: position it properly over the T-bus connector, hook the lip over the lower edge of
the DIN rail, and use a rocking motion to snap the module into place.
All Click 223 devices must be grounded. To ground the device:
1
Connect a grounding wire (14 AWG) from one of the screw terminals marked PE (protective earth) to a grounded loca-
tion—for instance, to a lug bolt, if there is one on the cabinet for grounding, or to an earth ground terminal block.
2
Make sure that the lug bolt or earth ground terminal block is grounded.
For additional security, ground the DIN rail that the Click 223 is mounted on:
1
Connect the grounding wire from the DIN rail to a grounded location—for instance, if there is a lug bolt on the cabinet for
grounding, or to an earth ground terminal block.
2
Connect another grounding wire from the chosen location to earth ground.
2
Wire earth ground
3
Wire the screw terminals
If your installation has an underground cable run,
protect the sensor and the main traffic cabinet from
surges on the underground cable run by using two
Click 223 devices: one in the pole-mount cabinet, one
in the main traffic cabinet, as shown at right.
Note.
The Advance does have onboard surge protec-
tion, so you could install a Click 223 surge protector
only in the main traffic cabinet, and rely on the sensor
to protect itself from surges. If you are in an area with
lots of surges, however, you may want to use a second
Click 223 just to be safe.
