The external protective earth is connected to the equipotential bonding terminal on the housing of the transmitter. It must
always be connected (see Fig. 7.17).
For the connection of the power cable to the transmitter, see box "Cable connection", Fig. 7.17 and Tab. 7.12
.
Attention! According to IEC 61010-1:2010, a switch must be provided near the measuring instrument, easily ac-
cessible and marked as a disconnection device for the measuring instrument.
If the measuring instrument is used in an explosive atmosphere, the switch should be installed out-
side the explosive atmosphere. If this is not possible, the switch should be installed in the least haz-
ardous area.
Attention! The degree of protection of the transmitter will only be guaranteed if the power cable fits firmly and
tightly in the cable gland.
Attention! Observe the "Safety instructions for the use in explosive atmospheres" (see document SIFLUXUS).
Cable connection
