Product Markings - Mettler Toledo IND780 Guia De Instalacion

United States refer to the control drawing 64069877 and the current version of the National
Electrical Code (NFPA 70, Articles 500 – 504) and ANSI/ISA-RP12.6 for specific requirements. For
installation in Canada refer to the control drawing 64069877 and the Canadian Electrical Code
C22.1 Section 18, Appendix F. If installed outside the US and Canada, refer to the electrical
regulations for the country of installation for specific wiring requirements.
As a general guide, if a signal is rated as non-incendive or intrinsically safe, and is connected to
another device that is non-incendive or intrinsically safe, and the non-incendive field circuit
parameters agree in the correct manner, no special protection of the wiring is required. On the
control drawings and certificates in this manual, a list of non-incendive field circuit and entity
parameters for the Analog load cell, PDX digital load cell (except for ATEX and IECEx), and Flow
meter connections of the IND780 terminal is given. These parameters include voltage, current,
power, capacitance and inductance values. Comparing these values from the IND780 terminal with
the values of other approved apparatuses (such as load cells) provides the ability to use the
IND780 terminal with METTLER TOLEDO load cells and other manufacturers' load cells and
approved apparatuses in an approved system. This process is explained in the next chapter.
If a signal cannot be classified as non-incendive or intrinsically safe, follow the electrical
regulations for the country of installation for specific wiring requirements of incendive equipment in
a Division 2 or Zone 2/22 area. This may require conduit or special protective cabling.

Product Markings

The analog load cell versions of both enclosure types of the IND780 terminal have received
Division 2 and Zone 2/22 approvals from UL and DEMKO. Terminals ending in Y96 are approved
for use in the US and Canada; terminals ending in Z97 are approved for use in Europe.
Up to four analog load cell option cards can be installed in the IND780 terminal with the following
factory numbers (replace y with 1):

The flow meter versions of both enclosure types of the IND780 terminal have received Division 2
and Zone 2/22 approvals from UL and DEMKO. One or two flow meter option cards can be
