the wooden strip has all the connections. start with 24v. its not very clear in the photos i guess the exchange line connections start at the left followed by the extensions . is it a swedish item .does the name or designation plate give any clue ie the number of exchange lines , then the number of extensions the last connections on the right woiuld appear to be the power input.
