2. Continue attaching any other module(s) to the mounting rail as described in Step 1.
ABB recommends the use of end clamps to prevent modules from sliding left
and right on the mounting rail.
3.
When all modules are installed, place an end clamp tight up against the left side of the
left-most module on the mounting rail. Then place a second end clamp tight up against
the right side of the right-most module on the mounting rail.
Grounding clips built into the AWIN GW100 module make contact with the upper
edge of the DIN rail during installation. This provides a ground path from the
DIN rail to the module. To ensure proper shielding of the module(s) through the
DIN rail, ABB recommends connecting the DIN rail directly to a low-impedance
earth ground.
Connect the DIN rail to protective earth ground using a grounding terminal block. To re-
move AWIN GW100 follow the procedure shown in
Figure 6 .
