7.8 Outputs
For the connection of the output cable to the transmitter, see box "Cable connection", 
p. 69
 and 
Tab. 7.14
.
Attention! Observe the "Safety instructions for the use in explosive atmospheres" (see document SIFLUXUS,
SIFLUXUS_808_FM and SIFLUXUS_1N62).
Attention! The outputs may only be connected to a low voltage circuit (max. 30 V AC or 42 V DC against earth).
