The weighing platform is part of a modular system. The associated components, such as terminals, application pacs and the extensive range of accessories, allow you to assemble a weighing system ideally tailored to the needs of your operation.
The explosion-protected weighing platform is approved for operation in Zone 2 (gases) and
Zone 22 (dusts) hazardous areas. There is an increased danger of injuries and damage when using the weighing platform in hazardous areas! Exercise particular care when using in 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 and
22 only in conjunction with weighing terminals that have the appropriate approval and in­terface specification.
The connection cable may not be separated from the weighing terminal while it is
energised.
Selecting installation location
The foundation must be capable of safely
support the weight of the weighing plat­form at its support points when it carries the maximum load. At the same time, it should be so stable that no vibrations oc­cur during weighing operations. These re­quirements also apply when the weighing platform is integrated in conveying sys­tems and the like.
Ensure that vibrations due to machines
near the installation site are kept to a minimum.
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 stainless-
steel or hot-galvanised weighing platforms.

The equipotential bonding must be installed by a professional electrician when using the weighing platform in Zones 2 and 22. METTLER TOLEDO Service only has a monitoring and consulting function here.
Connect equipotential bonding (PA) of all devices (weighing platform and service
terminal) in accordance with the country-specific regulations and standards. In the process, make sure that all device housings are connected to the same potential via the PA terminals.

5.4 Removing and replacing the load plate at MCC weighing platforms
Removing the load plate
• Remove the load plate by lifting the two side handles vertically (1.) and pivoting outward (2.).
Replacing the load plate
• After mounting the load plate, swing the handles inward (3.) and reengage in initial position (4.), i.e. the handles must be in the bottom position and vertical.
When the handles are correctly engaged, it should not be possible to lift off the load plate.

The weighing platform has such a rugged design that no damage should result if the maximum weighing capacity is occasionally exceeded.
The static load-bearing capacity, i.e. the maximum permissible load, is dependent on the type of loading (Positions A – C).
Maximum permissible load
A with central load
B with side load
C with one-sided corner load
Falling loads, shocks and lateral impacts
must be avoided.

Maintenance 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 stainless steel) and on the environmental conditions prevailing at the installation location. Remove dirt and deposits at regular intervals from the outside and inside of the weighing platform.
5.1 Notes on cleaning
CAUTION
Incorrect 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 the weighing platform.
• Be particularly careful when cleaning the measuring cell.
Powder-coated/enamelled version, dry surroundings
• Wipe with a damp cloth.
• Use household cleaning agents.
Stainless-steel and hot-galvanised versions
• 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 regular intervals.
• Only use disinfectants and cleaning agents in accordance with the manufac­turer's specifications and instructions.

5.2 Subsequent treatment
Carry 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 cell
The load plate has to be removed in order to clean the measuring cell. Please refer to the next section for MCC weighing platforms.
CAUTION
The measuring cell can be damaged!
• During cleaning work, never touch, direct an airflow against or spray the rubber diaphragm (1) of the measuring cell.
• Blow out dirt or flush with a medium­power water jet.
