The shaper is a separate PCB connected to the mother board (with 4-wire cable) and the cascade (with 2-wire cable with XT60 connector). The main purpose of the shaper is to generate pulse according to IEC/EN 61000‑4‑2.

In order to prevent losses from the corona effect, all conductive surfaces on the top layer of the assembled cascade (except the flat-cable connector) can be coated with corona-protective insulating material (e.g. Plastik70 from Kontakt Chemie or similar).
+Sharp and round tips according to the standard including 4mm connectors should be custom made.

### Claws and strap
The strap is 2 m 34-wire flat cable connected to the cascade with 34-bin boxer connector. The other end of the strap is connected via 34-pin boxer connector to PCB with claws for GND contact. The main purpose of the claws is to provide easy way of connecting the ground of O-ESD, while the strap connects the O-ESD and the claws.
