Breaker Data Adapter (BDA)

WL Circuit Breaker

Connection to WL Circuit Breakers

To operate the BDA, it must be connected to the target system (e.g. a PC) on one side and a circuit breaker on the other. Different scenarios are possible depending on the application.

For WL Circuit Breakers, two basic methods are available for connecting the BDA, temporary of permanent installation.

Temporary

If the BDA is to be used as a local parameterization tool and several circuit breakers are to be set in succession, the local front interface of the trip unit can be used. The cable required is supplied with the BDA. An additional 24V DC power supply unit is also required if the circuit breaker is not yet supplied with power via the CubicleBUS. For this purpose, a voltage connection is located on the top of the BDA next to the interface to the circuit breaker.

In temporary mode, the BDA can be quickly secured to any switchgear cubicle using magnets on the back.

Note: Do not use temporary magnetic installation for BDA where it can fall into energized parts.

Permanent

The trip unit interface through the front connection is not suitable if a BDA or BDA Plus is to be permanently connected to a WL Circuit Breaker. The connection on the last CubicleBUS module, such as the COM16 module, or one of the other modules, is more suitable. In this case, a cable is supplied with the BDA that can be connected directly

to the RJ45 plug-in contact of the CubicleBUS module. Typically,

a BDA Plus is used for permanent installation. The DIN rail installation kit supplied is used to secure the device.

The principle regarding the power supply is the same as for temporary operation: if the CubicleBUS is supplied with power, the BDA will also operate without an extra power supply unit. Otherwise, the BDA must also be connected to a 24V DC power supply unit.
