WARNING — Electric voltage! Install the device only if you have the necessary electrical engineering knowledge and experience. Incorrect installation endangers life and can cause serious property damage (e.g., fire). Apply the "five safety rules" (DIN VDE 0105, EN 50110): disconnect from power; secure against being re-connected; ensure there is no voltage; connect to earth; cover or barricade adjacent live parts. Use suitable personal protective clothing and only suitable tools/measuring devices. Check the type of supply network (TN, IT, TT system) to confirm proper power supply conditions.
The device has jumpers/switches for: (1) Station Selector — sets the address of the default outdoor station; (2) X10/X1 selector switches — set the tens/units address digits of the indoor station (X100/X200), configured via the "Light" button; (3) Master/Slave function — only one indoor station per apartment should be set as "Master" (M/S on); all additional indoor stations in the same apartment must be set as "Slave" (M/S off); (4) Terminal resistor — set to "RC on" on the last device of the line in video or mixed audio/video installations; (5) a/b bus connection and door bell connection terminals.
Used electric and electronic devices must not be disposed of with domestic waste — the device contains valuable raw materials that can be recycled. Dispose of it at an appropriate collecting depot. ABB products meet EU-Directive 2002/96/EG (WEEE), 2002/95/EG (RoHS), and EU-REACH ordinance requirements.
