2.2 Enclosure Disassembly
The 1280 FlexWeigh Concrete Batcher enclosure must be opened to connect cables.
Ensure power to the indicator is disconnected, then open the enclosure.
2.3 Option Cards
Table 2-1 lists the option cards that are used in the 1280 FlexWeigh Concrete Batcher.
2.4 Cable Connections
The 1280 FlexWeigh Concrete Batcher provides 13 cord grips for cabling into the controller. The parts kit includes cord grip
plugs to prevent moisture from entering the enclosure. Install these plugs into all cord grips that will not be used in your
application.
Use the cable grounding instructions for wiring into the indicator.
NOTE: An additional adhesive label (PN 121108) is included in the parts kit and can be installed at the installer’s discretion
indicating correct terminal block numbering.
2.4.1 Cable Grounding
Cables routed through the cord grips should be grounded against the indicator enclosure. Follow cable grounding instructions
in the 1280 Enterprise Series Technical Manual (PN 167659).
