1 General information

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.

2 Safety precautions

▲ 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.

3 Equipotential bonding

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.

4 Operating limits

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).
