2. INSTALLATION

2.1 External Connections

Scale Base with Connector to T71P
Ohaus bases with a circular connector can be attached to the external load cell connector.
To make the connection, plug the base's connector onto the external load cell connector, and then rotate the locking ring
clockwise.
To connect an Ohaus base with a circular connector to the T71XW (which does not have an external connector), the Load
Cell Cable Adapter Kit p/n 80500736 may be used to make the connection. Only use this attachment method if the system will
not be used in a Washdown environment. This cable connects to the terminal block inside the T71XW and has an external
connector on the other end.
RS232 Interface Cable to T71P
Connect the optional RS232 cable to the RS232 connector.
