2.2 External Connections
2.2.1 Scale Base with Connector to T51P
Ohaus bases with a connector can be attached to the external load cell connector (Figure 1-1, item 14). Refer to section 2.3.2
for bases without a connector. To make the connection, plug the base connector onto the external load cell connector. Then
rotate the base connector’s locking ring clockwise.
For connecting bases with a connector to a T51XW (which does not have the external connector), a Load Cell Cable Adapter
Kit p/n 80500736 is available as an accessory. This kit connects to the terminal block inside the T51XW and has an external
connector on the other end.
2.2.2 RS232 interface Cable to T51P
Connect the optional RS232 cable to the RS232 connector (Figure 1-1, item 16).
2.2.3 AC Power to T51P
Connect the AC power cord (supplied) to the power receptacle (Figure 1-1, item 11), then connect the AC plug to an electrical
outlet.
2.2.4 AC Power to T51XW
Connect the AC plug to a properly grounded electrical outlet.
2.2.5 Battery Power to T51P
The indicator can be operated on alkaline batteries (not supplied) when AC power is not available. It will automatically switch
to battery operation if there is power failure or the power cord is removed. The indicator can operate for up to 80 hours on
battery power.
Remove the battery cover (Figure 1-1, item 9) and install 6 C-type (LR14)
alkaline batteries in the orientation specified. Re-install the battery cover.
During battery operation, the battery charge symbol indicates the battery status.
The indicator will automatically turn-off when the batteries are fully discharged.
