2.3 Backplate Removal
Remove the backplate of the 680 to connect cables and to gain access to the 680 board and power supply.
Before opening the unit, ensure the power cord is disconnected from the power outlet.
1. Place the 680 face-down 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.
Figure 2-4. Removing the Backplate
The 680 ships with only four screws securing the backplate. The remaining backplate screws are included in the
parts kit. For reassembly, torque backplate screws to 15 in-lb (1.7 N-m).
2.4 Cable Connections
The 680 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. Three of the four free cord grips come with a plug
installed to prevent moisture from entering the enclosure. Depending on the application, remove the plugs from cord grips to be
used and install cables as required. The recommended cable strip length is 0.25'' (7 mm) for all 680 connectors.
See Figure 2-5 for the recommended assignments for the 680 cord grips.
Only connect unit to equipment certified to IEC 60950, IEC 62368, IEC 61010 or similar.
Figure 2-5. Recommended Cord Grip Assignments
Do not have open/bare wires outside of the enclosure. Make sure no stripped portion of cable is on the outside
of the cord grips.
