1 General informationThe weighing platform is part of a modular system. The associated components, such asterminals, application pacs and the extensive range of accessories, allow you to assemble aweighing system ideally tailored to the needs of your operation.2 Safety precautions▲ The explosion-protected weighing platform is approved for operation in Zone 2 (gases) andZone 22 (dusts) hazardous areas. There is an increased danger of injuries and damagewhen using the weighing platform in hazardous areas! Exercise particular care when usingin such areas. The rules for behaviour are based on the concept of "Safe Distribution"established by METTLER TOLEDO.▲ Explosion-protected weighing platforms may be used in hazardous areas of Zones 2 and22 only in conjunction with weighing terminals that have the appropriate approval and interfacespecification.▲ The connection cable may not be separated from the weighing terminal while it isenergised.Selecting installation location▲ The foundation must be capable of safelysupport the weight of the weighing platformat its support points when it carriesthe maximum load. At the same time, itshould be so stable that no vibrations occurduring weighing operations. These requirementsalso apply when the weighingplatform is integrated in conveying systemsand the like.▲ Ensure that vibrations due to machinesnear the installation site are kept to aminimum.Ambient conditions▲ Use powder-coated/enamelled weighing platforms only in a dry environment.▲ In a damp environment, in wet operation or when working with chemicals: use stainlesssteelweighing platforms.3

3 Equipotential bondingThe equipotential bonding must be installed by a professional electrician when using theweighing platform in Zones 2 and 22. METTLER TOLEDO Service only has a monitoring andconsulting function here.➜Connect equipotential bonding (PA) of all devices (weighing platform and serviceterminal) in accordance with the country-specific regulations and standards. In theprocess, make sure that all device housings are connected to the same potential via thePA terminals.Equipotential bonding with KA...(1) Serrated lock washer A 4.3 DIN 6798(2) Hexagonal lock nut M4 DIN 934(3) Washer 4.3 DIN 125(4) Base frame(5) Equipotential bonding clampMounting materials are enclosed with theID7xx, IND690xx or IND4..xx weighingterminal.Equipotential bonding with KB..., KCC...(1) Frame body(2) Fillister head screw M5x12 DIN 912(3) Washer 5.3 DIN 125(4) Serrated lock washer 5.3 DIN 6798(5) Washer 5.3 DIN 125(6) Hexagonal lock nut M5 DIN 934(7) Hexagonal lock nut M4 DIN 934(8) Washer 4.3 DIN 125(9) Serrated lock washer A 4.3 DIN 6798(10) Potential plate weighing platform(11) Equipotential bonding clampMounting materials are enclosed with theID7xx, IND690xx or IND4..xx weighingterminal.4

4 Operating limitsThe weighing platform has such a rugged design that no damage should result if themaximum weighing capacity is occasionally exceeded.The static load-bearing capacity, i.e. the maximum permissible load, is dependent on the typeof loading (positions A – C).Maximum permissible loadAKA15s KA32sA 50 kg 50 kgB 40 kg 40 kgC 30 kg 30 kgBCKB60 KCC150KCC300A 120 kg 500 kgB 80 kg 300 kgC 40 kg 150 kgA with central loadB with side loadC with one-sided corner load▲ Falling loads, shocks and lateral impactsmust be avoided.5

5 Cleaning the weighing platformMaintenance of the weighing platform is limited to regular cleaning and subsequent oiling.The procedure depends both on the type of surface (powder-coated/enamelled or stainlesssteel) and on the environmental conditions prevailing at the installation location. Remove dirtand deposits at regular intervals from the outside and inside of the weighing platform.5.1 Notes on cleaningCAUTIONIncorrect use of cleaning agents may cause damage to the weighing platform!•Use only such cleaning agents that do not act on the plastics used in theweighing platform.•Be particularly careful when cleaning the measuring cell.Powder-coated/enamelled version, drysurroundings• Wipe with a damp cloth.• Use household cleaning agents.Stainless-steel version• Wipe with a damp cloth.• Water jet up to 60 °C.• Use household cleaning agents.Corrosive surroundings• Water jet up to 60 °C.• Remove corrosive substances at regularintervals.• Only use disinfectants and cleaningagents in accordance with the manufacturer'sspecifications and instructions.6

5.2 Subsequent treatmentCarry out the following subsequent treatment in order to protect the weighing platform:• Rinse the weighing platform with clear water.• Dry off the weighing platform with a lint-free cloth.• Treat the inside and outside of the weighing platform with an oil suitable for foodstuffs.5.3 Cleaning the measuring cellThe load plate has to be removed in order to clean the measuring cell. Please refer to the nextsection for KCC weighing platforms.CAUTIONThe measuring cell can be damaged!• During cleaning work, never touch, directan airflow against or spray the rubberdiaphragm (1) of the measuring cell.• Blow out dirt or flush with a mediumpowerwater jet.7

5.4 Removing and replacing the load plate at KCC weighing platformsRemoving the load plate• Remove the load plate by lifting the twoside handles vertically (1.) and pivotingoutward (2.).Replacing the load plate• After mounting the load plate, swing thehandles inward (3.) and reengage ininitial position (4.), i.e. the handles mustbe in the bottom position and vertical.When the handles are correctly engaged, itshould not be possible to lift off the loadplate.8
