The BPS 8 is connected to the MA 8
-
01/MA 8
-
02 via the KDS S-M12-5A-M12-5x-P1-xxx interconnection
cable. The voltage supply is connected via the PWR IN HOST/RS485 socket.
7.4.4 Termination of the RS 485 interface
Permanently installed termination networks are present in the MA 8
-
01 and the MA 8-02 which differ in
terms of resistance values. The resistor network terminates the outgoing RS 485 data interface, as shown
in Figure 7.11, and cannot be switched off.

CAUTION
Degree of protection IP 67!
Degree of protection IP 67 is achieved only if the connectors and caps are screwed into place!
CAUTION
Connect functional earth!
Ensure that the functional earth (FE) is connected correctly.
Fault-free operation is only guaranteed if the functional earth is connected properly.
