Shielding concept

Use shielded cables for connecting the motor and feedback. Place the cable shields as close as possible to the terminal to minimize electromagnetic interference.

There are two ways to connect a cable shield directly to the terminal:

With a ZB8510 shield busbar
With a ZB8511 shield busbar clamp

Mounting example

Example of a motor cable with PE core on a ZB8510 shield busbar.

Additional material required:

1 x ZB8500 | clamp strap [7]
1 x ZB8510 | shield busbar [3]
2 x ZB8520 | mounting rail holder [1]
1 x ZB8530 | U-clamp terminal [9]

Procedure:

1. Ensure that the DIN rail [2] is connected to the metal rear panel of the control cabinet over a large area.

2. Attach the mounting rail holders [1] to the DIN rail and mount the shield busbar [3] to them.

3. Strip the cable [5] so that the cable shield is exposed over a length of approx. 20 mm in the area of the shield busbar.

4. Wire the cores [4] of the cable to the terminal.

5. Attach the exposed cable shield [6] to the shield busbar using the clamp strap [7].

6. Tighten the knurled screw [8] to the stop.

7. Attach the U-clamp terminal [9] to the shield busbar.

8. Connect the PE wire [10] of the cable to the U-clamp terminal.
