breakers are sensitive to all currents. Pursuant to DIN VDE 0160,
5.5.3.4.2, it is not allowed by to use any other current operated cir-
cuit breaker as a DC component within the leakage current might
prevent activation of the circuit breaker. The maximum admissible
current for triggering this all-current-sensitive circuit breaker must
not exceed the value I∆N=0.3 A.

INFO!
• BÖHNKE + PARTNER checks the entire lift control unit before
supplying it. We document the status of supply in the circuit dia-
grams and in the protocol of the setup and service menu.
• Each control unit comes with circuit diagrams and technical docu-
mentation clearly marked with the control unit number.
• All 24 V DC control signals (in- and outputs) are galvanically isol-
ated from the control electronics.
• The control unit is to be installed in adherence to our circuit dia-
grams.
• The 24 V DC control lines and the data lines RS232, RS485, USB,
CAN, LON, Ethernet and telephone must be laid separately from
the load lines!
• When installing the control unit, you must adhere to the technical
data that has been used during production according your order.
