General information
Note Both output loads must be connected to ensure complete and correct operation within the technical specification.
Open circuit of one of the two outputs will not affect the connected output, but would result in a loss of transmitter supply voltage of up to 0.7 Volt.
Supplementary information Observe the certificates, declarations of conformity, instruction manuals, and manuals where applicable.
