Click 222 System Surge
QUICK START GUIDE

Wire earth ground
All Click 222 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 location—for instance, to a lug bolt, if there is one on the cabinet for grounding, or to an
earth ground terminal block.
2
Connect another grounding wire from there to earth ground.
For additional security, ground the DIN rail that the Click 222 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 there to earth ground.

Mount the device
The Click 222 mounts over a T-bus for power and communication:
1
If the Click 222 was shipped with the T-bus connector attached,
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 sliding
them together until you hear them snap into place.
4
Mount the Click 222 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.
5
If you are using multiple Click 222 devices, follow steps 1–4 to
mount them next to the first device.
