Connection terminals
- The device is equipped with one or two connection terminals, depending on the version.
- Detachable screw terminals were used.
- The terminals have the same number of tracks but a different raster. They cannot be accidentally changed and / or connected backwards.
- Connection blocks have descriptions of individual tracks to facilitate assembly.
