2.1.2.3 Composer Elite System Grounding Requirement
CAUTION
The Sensor Control Unit and Acoustic Sensor must be
grounded for proper performance of Composer Elite.
The following grounding method is recommended:
1 Verify that the Reactor is connected to a good, reliable earth ground (refer to
section 2.1.2.2, Earth Ground Requirement, on page 2-3 ). Use a solid copper
strap, at least 0.08 cm (0.030 in.) thick by 2.5 cm (1 in.) wide, and as short as
practical, for the connection between Reactor and earth ground (see
Figure 2-1 ).
2 Use a solid copper strap, approximately 0.08 cm (0.030 in.) thick by
2.5 cm (1 in.) wide, and as short as practical, between the Sensor Control Unit
ground stud (see
Figure 2-1 ) and the Reactor. A ring terminal soldered to the
ground strap will allow for a good connection to the ground stud and convenient
removal or installation.
3 Connect the Acoustic Sensor to earth ground by one or both of the
following methods:
3a Use the M4 mounting holes provided on the Acoustic Sensor to attach the
Acoustic Sensor to a metal mounting surface that is connected to earth ground
(see
Figure 2-1 and section 2.2.2 on page 2-9 ).
or
3b Connect the Acoustic Sensor's outlet tubing to process tubing that is connected
to earth ground (see
Figure 2-1 and section 2.2.2 on page 2-9 ).
