WL UL 489_Com-section 4 1/28/05 1:14 PM Page 3 Breaker Data Adapter (BDA) WL Circuit Breaker BDA in Offline Mode (or BDA Plus) In offline mode, the BDA or BDA Plus is only connected to a laptop (represents all input/output devices). All the required parameters can be set in this operating mode and saved for later use (download to the circuitbreakers). No power is supplied via the laptop COM interface, which means that an additional power supply unit (24V DC) must be connected to the BDA.
