Power supply
WARNING
Risk of injury through electric shock and damage to the device!
Bring the Bus Terminal system into a safe, voltage-free state before starting mounting, disassembly or wiring of the Bus Terminals!
Note
Link the grounds of the power supply units for Us of the Bus Coupler and all manual operating modules with a low-resistance connection
For interference-proof operation of the K-Bus extension, the ground of the K-Bus power supply for the bus coupler must be connected with low-resistance to the grounds of the K-Bus power supplies for all its manual operating modules (see figure above)!
Calculation of the K-Bus sum current for the bus coupler Because the supply voltage for the K-Bus (Us) is fed into each manual operating module individually, the K-bus current consumption of the manual operating modules does not have to be taken into account when calculating the K-bus total current of the bus coupler. |
