FLUXUS WW 8 Connection
62 UMFLUXUS_WWV1-1EN, 2018-02-28
8.2 Power supply
The external protective earth is connected to the equipotential bonding terminal on the housing of the transmitter FLUXUS
F704**-A2 (see Fig. 8.13). It must always be connected.
For the connection of the power cable to the transmitter, see box "Cable connection", Fig. 8.13 and Tab. 8.10.
For the voltage, see Technical specification.
Attention! Observe the "Safety instructions for the use in explosive atmospheres" (see SIFLUXUS document).
Attention! According to IEC 61010-1:2010, a switch has to be provided near the measuring instrument in the
building installation, easily accessible for the user and marked as a disconnection device for the mea-
suring instrument.
If the transmitter FLUXUS F704**-A2 is used in an explosive atmosphere, the switch should be in-
stalled outside the explosive atmosphere. If this is not possible, the switch should be installed in the
least hazardous 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.
Cable connection
• Remove the blind plug from the transmitter to connect the cable (if present).
• Prepare the cable with an M20 cable gland. The used cable has to have a wire cross-section of 0.5…1.5 mm².
• Push the cable through the cap nut, compression part and basic part of the cable gland.
• Insert the cable into the housing of the transmitter.
• Screw the sealing ring side of the basic part tightly into the housing of the transmitter.
• Fix the cable gland by screwing the cap nut onto the basic part.
• Connect the cable to the terminals of the transmitter.
