Mounting and wiring
BC315020 Version: 2.1.0
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 0.08mm
2
and 2,5mm
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 10A 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.
