• Comply with the installation and safety instructions in the Operating Instructions.
• Install the device according to the manufacturer's instructions and any other valid standards and regulations.
• Only install the devices in media for which the wetted materials have sufficient durability.
• Pay attention to the maximum process conditions according to the manufacturer's Operating Instructions.
• At high medium temperatures: note flange pressure load capacity as a factor of temperature.
• The pertinent guidelines must be observed when intrinsically safe circuits are connected together acc.
EN 60079-14 (Proof of Intrinsic Safety).
• To maintain the ingress protection of the housing, install the housing cover and cable glands correctly.
• Close unused entry glands with sealing plugs.
• The potential matching line should lead from the intrinsically safe associated apparatus
(in the non-hazardous area) and the probe (in the explosion-hazardous area).
• Level probes with ground tubes are suitable for use in gases of Group IIC, IIB and IIA.
• Level probes without ground tubes are suitable for use in gases of Group IIC and IIB if there is no electrostatic
charging of the probes.
These probes are indicated by the warning sign "Avoid Electrostatic Charge".
• Install the device to exclude impact and friction sparks on the aluminium housing.
• On installations requiring overvoltage protection to comply with national regulations or standards
(e.g. EN 60079-14), this device shall be installed using an overvoltage protector (e.g. HAW262Z, HAW56xZ
from Endress+Hauser).
• The device is designed for operation in Zone 21 or Zone 1 (housing) as well as Zone 20 or Zone 0 (probe).
Its suitability in the event of potentially explosive gas-air and dust-air mixtures occurring simultaneously
requires further assessment.
• F16 housing: Do not clean the transparent cover in an explosive atmosphere.
• F16 housing: Using a plug is only permitted for gas group IIB.
