Backplate Removal

Remove the backplate of the 682 to connect cables and gain access to the 682 board and power supply.
WARNING: Before opening the unit, ensure the power cord is disconnected from the power outlet.
1. Place the 682 facedown on an anti-static work mat.
2. Remove the screws holding the backplate to the enclosure.
3. Lift the backplate away from the enclosure and disconnect the ground wire from the backplate.
NOTE: The 682 ships with only four screws securing the backplate. The remaining backplate screws are included in the
parts kit. For reassembly, torque backplate screws to 12 in-lb (1.4 N-m).

Cable Connections

The 682 provides five cord grips at the bottom of the enclosure for cabling into the indicator. One of the cord grips is used for
the power supply and the other four are used to accommodate the load cell cable and the serial, digital inputs and outputs,
Ethernet, micro USB or the optional analog output communications cables. A version of the 682 with an external RJ45
connector and cap is available. Cable plugs are included in the parts kit and must be installed in open cord grips to prevent
moisture from entering the enclosure. Use the attached cap to seal the optional RJ45 connector when not in use. See the
following sections to install cables as required for the application. The recommended cable strip length is 0.25 in (7 mm) for all
682 connectors. See Figure 2-5
IMPORTANT: Prohibit open/bare wires outside of enclosure. Ensure stripped portion of cables are entirely inside cord grips.
IMPORTANT: Properly seal cord grips to prevent moisture damage inside of the enclosure. Cable plugs must be installed in
unused cord grips. Cord grip dome nuts, around a cable or a plug, must be torqued to 22 in-lb (2.5 N-m). The cord grip nut
against the enclosure must be torqued to 33 in-lb (3.7 N-m).
WARNING: Only connect unit to equipment certified to IEC 60950, IEC 62368, IEC 61010 or similar.
