The Marantec 114590 Terminal Block is an original replacement wiring connector designed for select Marantec garage door openers. This plug-in terminal strip provides secure, low-voltage connections between the opener’s control board and approved accessories, such as wall controls, safety sensors/photo eyes, and other compatible control peripherals. It restores reliable electrical contact when the original connector is worn, damaged, or missing, helping resolve intermittent operation and wiring-related faults.
As an OEM Marantec part, the 114590 Terminal Block is intended only for models that specifically list this part number; always verify compatibility in your opener’s manual or parts diagram. For installation, disconnect power to the operator, note existing wire positions, and transfer wires one at a time to the new block per the wiring diagram. Ensure all screws are snug and polarity is observed where applicable. This component handles low-voltage control circuits; no programming is typically required when replacing the terminal block alone, but any connected accessories should be tested after power is restored. Using the correct Marantec 114590 Terminal Block helps maintain dependable operation in residential or light commercial garage door opener applications.
