Installation of the intelligent Tab
Controller hardware
The intelligent Tab Controller components are to be mounted onto a
35 mm DIN rail, inside an electrical cabinet. For more information,
refer to
"5.2.1. Installation place and mounting direction" on page 5
.
Install the three intelligent Tab Controller hardware components as
follows:
1
Place the module over the top of the DIN-35 rail so that the
upper hook on the rear face is hooked in.
2
Push the module in direction 'a' until the lower hook snaps into
the rail.
3
If necessary, pull the lever on the lower parts of the module in
direction 'b' to click the module onto the rail. Use a flat-blade
screwdriver if necessary.
