The temperature limits apply under the following conditions:
• The instrument is installed and operated in accordance with the installation directions given in the installation and operating instructions.
• The instrument is not heated up by any additional heat radiation (direct solar radiation, heat from adjacent plant parts) so causing it to operate above the permissible ambient temperature range.
• Insulation is not hindering free ventilation of the signal converter housing.
2.1 OPTIFLUX 2000 / 4000
2.1.1 Compact versions
• The OPTIFLUX 2100 C / 4100 C is suitable for an ambient temperature of -20...+40°C.
• For dust hazardous areas, the maximum surface temperature is 120°C.
• The minimum process temperature for all DN sizes is -20°C.
• The maximum process temperature is determined by the temperature class T4 of the gas
hazardous area of concern and type of protection of the coil housing.
• The process temperature range is often limited further by the liner type used (refer to the Quick Start).

3 ELECTRICAL CONNECTIONS
3.1 Installation instructions
When used in a potentially gas explosive atmosphere, certified cable entry devices must be used that are suitable for the application and correctly installed.
When used in a potentially dust explosive atmosphere, vertified cable entries with a degree of ingress protection of at least IP6X according to IEC 60529 must be used that are suitable for the application and correctly installed.
Unused openings must be closed with suitable certified closing elements.
The field coils in type of protection "mb" must be protected by a 160 mA fuse. The breaking capacity of the fuse must be in accordance with the prospective short circuit current of the supply. This concerns following flowmeters:
OPTIFLUX 2100 C / 4100 C DN10...20 ("mb")
INFORMATION!
The internal field coil fuses of the IFC 100 converter fulfil the above mentioned requirement with respect to the breaking capacity. The OPTIFLUX 2100 C / 4100 C compact flowmeters are normally delivered with two Ex e certified M20x1.5 cable glands, clamping range ∅6...12mm.

4 MAINTENANCE AND SERVICE
4.1 Maintenance and service
The OPTIFLUX flowmeters are maintenance free with respect to the flow metering properties. Within the scope of periodic inspections required for electrical equipment installed in hazardous areas it is recommended to check the flow meter and converter housing for signs of the corrosion. This is especially important for the flameproof Ex d flowmeter or coil housing of sizes DN25...150.
Specific notes for Ex d flowmeters, sizes DN25...150:
• In case of replacement of one (or more) of the four M6 hexagon socket head cap screws which connect the IFC 100 converter housing with the OPTIFLUX 2000 / 4000 flowmeter, equivalent types must be used, that are M6x16 hexagon socket head cap screws to ISO 4762, steel quality A2-70 or A4-70.
• If needed, contact please the manufacturer for information on the dimensions of the falmeproof joints.
