shown above, then no special protection is required for the wiring. Always refer to
the electrical regulations for the country of installation for specific wiring
requirements.

Analog Load Cell

The analog load cell connection is rated non-incendive on the IND560xx terminal
by both UL and DEMKO. The non-incendive field circuit wiring (NIFW) parameters
are listed here:

Non-sparking Approval

The IND560xx has been approved as a non-sparking device. This permits
connection of an IDNet platform which also has a non-sparking approval, such as
High Precision bases using the "T-Brick" cell. Note that the base must also have a
non-sparking approval.
NOTE: While the IND560xx with IDNet interface has been given a non-
sparking approval, at this time no METTLER TOLEDO High Precision IDNet
bases are approved for use within an area rated as Division 2 or Zone 2/22
in the United States or Canada.

Incendive Inputs and Outputs

If a specific input or output is rated incendive, then special wiring precautions must
be taken to protect the wiring in the Division 2 or Zone 2/22 area. Refer to the
electrical regulations for the country of installation for specific wiring requirements.
Note that the United States requires installation of conduit hubs and conduit to
protect incendive signals. Other locations may require conduit, special wire, or
certified glands. Refer to the first part of this chapter for details.
All inputs and outputs to the IND560xx terminal not listed in the section above as
non-incendive must be treated as incendive.
