Intended use
The isolating relay, delivered ex works, is used for electrical decoupling in parallel con-
nections. Depending on the drive (or motor current), up to max. 8 drives can be con-
nected in parallel, as the entire motor current flows through the central push-button.
The isolating relay is suitable for installation in flush-mounted switch or junction boxes
or in cable and parapet ducts.
The connection of external devices must be carried out in consultation with specialist
retailers.
Assembly
The unit is typically installed in the junction box next to the drive. It can also be installed
in a deep distribution switch box (with an all-over depth of at least 60 mm) behind an
Up/Down button. Wiring is carried out according to the connecting diagram.
