Sealing the Enclosure

When the IND560 terminal is used in a metrologically "approved" application, it
must be protected from tampering by use of seals. An optional sealing kit is
available from METTLER TOLEDO. The kit (Part number 71209388) contains all
the required hardware. The method used for sealing will vary depending upon local
requirements. The IND560 supports two methods of sealing – external and
internal.
External sealing is approved in the United States and Canada; however, when the
terminal is sealed externally, non-metrological components cannot be serviced
without breaking the seal. In Europe, internal sealing is possible, which permits
access to non-metrological components without breaking the seal. Check with
local authorities to determine which sealing method is appropriate.
External Sealing of the Panel-Mount
Enclosure
The panel-mount enclosure supports both two- and three-screw external sealing for
the United States and Canada. For external sealing of the panel-mount enclosure,
refer to Figure 2-56, Figure 2-57, and Figure 2-58 and follow these steps:
1. Ensure that the appropriate approval region has been selected in setup under
Scale, Type, Approval and that the Metrology security switch SW1-1 is in the
"on" position.
2. Replace the three Phillips-head screws that secure the rear panel to the
enclosure with the three through-hole screws provided in the sealing kit.
