Version: 2.0.0
DANGER
No unlimited voltage sources!
To comply with the UL requirements, Us must not be connected with unlimited voltage
sources.
Power contacts supply (Up)
The bottom six connections with spring-loaded terminals can be used to feed the supply for the peripherals.
The spring-loaded terminals are joined in pairs to a power contact. The feed for the power contacts has no
connection to the voltage supply for the BC electronics.
The spring-loaded terminals are designed for wires with cross-sections between 0.08 mm
2
and 2,5 mm
2
.
The assignment in pairs and the electrical connection between feed terminal contacts allows the connection
wires to be looped through to various terminal points. The current load from the power contact must not
exceed 10 A for long periods. The current carrying capacity between two spring-loaded terminals is identical
to that of the connecting wires.
Power contacts
On the right hand face of the Bus Terminal Controller there are three spring contacts for the power contact
connections. The spring contacts are hidden in slots so that they cannot be accidentally touched. By
attaching a Bus Terminal the blade contacts on the left hand side of the Bus Terminal are connected to the
spring contacts. The tongue and groove guides on the top and bottom of the Bus Terminal Controllers and of
the Bus Terminals guarantees that the power contacts mate securely.

Programming cable
Use the KS2000-Z2 programming cable for serial programming of the Bus Terminal Controller. This cable is
included in the scope of supply of the KS2000 software, or it can be ordered separately (order identifier
KS2000-Z2).

KS2000-Z2
The programming cable offers the option of programming the BCxx50 via the serial interface.
Attention
Do not interrupt the ground connection for the supply voltage
When the programming cable (between BCxx50 and PC) is connected, the ground connec-
tion of the Bus Terminal controller must not be interrupted or disconnected, since this may
destroy the programming cable.
