Preface
This publication is for the use of technical personnel responsible for installa-
tion of the ABB Type TB404 Toroidal Conductivity Sensor.
This instruction contains hardware installation instructions only. Wiring pro-
cedures, calibration procedures, etc., are covered in product instructions of
instruments compatible with the Type TB404 sensor.
Some sections of this instruction have been prepared in procedure format.
By treating each task as a separate entity, the procedures provide an easy
method for finding the information needed to perform each task. The proce-
dures can be removed and placed in separate folders or notebooks, or carried
to the job site.
The procedures have check boxes in the margin by each step. When per-
forming a procedure, check each box as each step is completed.
It is important for safety and operation that this instruction be read and
understood before attempting anything related to installation, operation,
maintenance or repair.
