Endress+Hauser 9
Safety instructions:
Zone 0
• In the event of potentially explosive vapor/air mixtures, only operate the device under atmospheric
conditions.
- Temperature: –20 to +60 °C
- Pressure: 80 to 110 kPA (0.8 to 1.1 bar)
- Air with normal oxygen content, usually 21 % (V/V)
• Associated devices with galvanic isolation between the intrinsically safe and non-intrinsically safe circuits are
preferred.
• If there is a risk of dangerous potential differences within Zone 0 (e.g. through the occurrence of atmospheric
electricity), implement suitable measures for intrinsically safe circuits in Zone 0 (e.g. in accordance with the
requirements of GB3836.13, GB3836.15, GB3836.16).
