### Grip
The grip is a separate PCB connected to the motherboard with 4-wire cable. The main purposes of the grip are: to house batteries, to provide physical grip of O-ESD and to house toggle switch and fire button.<br>

### Shaper
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&#8209;4&#8209;2.<br>

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).<br>

<br>Once a winding layer is completed, it shall be fully covered by layers of insulation paper. The total thickness of the insulating layer must be at least 0.2 mm. The first role of this insulation is to reduce the parasitic capacitances between adjacent wire layers. The second role is to increase the breakdown voltage between adjacent wire layers.<br>
<br>The completed secondary winding shall be covered by layers of insulation paper either fully or only in the area where the primary winding is going to be placed. The main role of this insulation is to increase the breakdown voltage between the two windings.<br>
<br>Once both windings are completed, the insulation from all wire ends shall be removed. Solder the terminals of the primary and secondary windings according to raster view. The beginning of the secondary winding (which is covered by the heat shrink tubing) shall be soldered to the pin denoted by the red circle in raster view.<br>

The cross sections of the core in the areas denoted by green ellipses should have gaps of 0.25&nbsp;mm to 0.3&nbsp;mm.
