uses the pin assignments 1: + and 2: —. Pins 3 and 4 are not

assignment 1+/1–.
24C-E cabinets are equipped with a fixed cable gland fitted with a
2-pole Mate-N-Lok mini connector. The extender is electrically
connected through the 24C cabinet.

pole Phoenix Euroblock connector block and the corresponding
input connector cable as the 24C cabinets to allow quick and easy
attachment of the extender to the 24C cabinet.
