Cable specifications
Power supply 6 … 16 V DC (Ex i) / 12 … 24 V DC (Ex d/de)
1)
OZ-BL-CY 2x1.5 mm² is only suitable for the power supply of the FLOWSIC600-XT.
Digital output, current output, encoder, pressure and temperature sensors
2)
RE-2Y (St)Yv with n x 2 x 0.5 mm² (n pairs) is suitable for transmitting the switching signals.
NOTICE:
Requirements on cables and installation
▸
Pay attention to the requirements in EN 60079-14 when selecting the
cables and during installation!
▸
FLOWSIC600-XT must be grounded according to EN 60079-14.
▸
Further legal requirements must be observed for use in explosive
atmospheres.
▸
Because of the danger of crosstalk, switching signals and the data signals
of the RS485 should not be routed in a cable with a common shield.
