Installing Miniature Rail-Mount Terminal Blocks in Air-Conditioning Systems
For installing air-conditioning systems, the Miniature Rail-Mount Terminal Blocks can be used without difficulty for the power connection and for connecting auxiliary components like a heating unit. The front-entry wiring plays an important role, especially in cases where wiring space is limited. Conductors can be wired from the front using push-in connection technology.
Depending on the specifications, the terminal strip often can be easily and flexibly expanded with additional terminal blocks, or easily commoned. The commoning is done with a push-in type jumper bar, without screws. If the connection needs to be supplemented with other components, the DIN-rail offers an easy option for expansion. If the junction box does not have a DIN-rail, the Mini Rail-Mount Terminal Blocks can also be fastened directly to the mounting plate using a flange or snap-in mounting foot and expanded that way. In the example application shown, the 2.5 mm² Mini push-button terminal blocks were installed on a DIN-rail 15.
