Safety instructions IND226x1 Safety instructions
The IND226x weighing terminal is approved for operation in Zone 1 and 21
hazardous areas as well as for Division 1 areas. The interface converter ACM200
may only be installed and operated in the safe area.
If the IND226x weighing terminal is used in hazardous areas, special care must be
taken. The code of practice is oriented to the "Safe Distribution" concept drawn up by
METTLER TOLEDO.
Competence ▲ The weighing system may only be installed, maintained and repaired by
authorized METTLER TOLEDO service personnel.
▲ The mains supply may only be installed by a specialist authorised by the owneroperator.
Ex approval ▲ No modifications may be made to the terminal and no repair work may be
performed on the modules. Any weighing platform or system modules that are
used must comply with the specifications contained in the installation
instructions. Non-compliant equipment jeopardizes the intrinsic safety of the
system, cancels the "Ex" approval and renders any warranty or product liability
claims null and void.
▲ The safety of the weighing system is only guaranteed when the weighing system
is operated, installed and maintained in accordance with the respective instructions.
▲ Also comply with the following:
– the instructions for the system modules,
– the regulations and standards in the respective country,
– the statutory requirement for electrical equipment installed in hazardous areas
in the respective country,
– all instructions related to safety issued by the owner.
▲ The explosion-protected weighing system must be checked to ensure compliance
with the requirements for safety before being put into service for the first time,
following any service work and every 3 years, at least.
Operation ▲ Prevent the build-up of static electricity. Always wear suitable working clothes
when operating or performing service work in a hazardous area.
▲ Do not use protective coverings for the devices.
▲ Protect the keyboard membrane against ultraviolet radiation.
▲ Avoid damage to the system components.4 Guide for installers 72203958C 11/12
Safety instructionsIND226xInstallation ▲ Only install or perform maintenance work on the weighing system in the
hazardous areas if the following conditions are fulfilled:
– if the intrinsically safe characteristic values and zone approval of the individual
components are in accord with one another,
– the owner has issued a permit ("spark permit" or "fire permit"),
– the area has been rendered safe and the owner's safety co-ordinator has
confirmed 11/12 there is no danger,
– the necessary tools and any required protective clothing are provided (danger
of the build-up of static electricity).
▲ The certification papers (certificates, manufacturer’s declarations) must be present.
▲ Lay cabling securely so that it does not move and effectively protect it against
damage.
▲ Only route cables into the housing of the system modules via the approved
earthing cable glands and ensure proper seating of the seals.Guide for installers 72203958C 11/12 5
