Installing the Hardware
This section shows how to install the parts of the 3500 Galvanic Interface onto
the backplane and then how to mount the backplane on a surface or in an
enclosure. The next section, Wiring the Hardware, shows how to connect the
installed interface to vibration transducers, monitors, and power supplies.
3.1
Before You Begin
Before you install the 3500 Galvanic Isolator Interface, use the following two
checklists to verify that the installation will meet approval requirements and to
check the accuracy of the output signal.
3.1.1
Verifying that the Installation will Meet Approval
Requirements
•
Make sure all installation work is carried out in accordance with all relevant
local standards, codes of practice, and site regulations.
•
Check that the hazardous-area equipment complies with the descriptive
system document.
•
If you cannot verify that the system meets approval requirements, refer to the
certificate for clarification of any aspects of intrinsic safety or contact Bently
Nevada or your local Bently Nevada representative for assistance.
•
Refer to the General Information section for appropriate applications.
3.1.2
Checking the Accuracy of the Output Signal
Before installing a 3500 Galvanic Isolator Interface system, use the information in
Section 3.1.2.1., Section 3.1.2.2. and the Specifications, to evaluate how the
Vibration Transducer Interface module will affect your instruments.
Note:
The 3500 Galvanic Isolator Interface can introduce additional ac and dc errors.
3.1.2.1
Affects on Monitors
The 3500 Galvanic Isolator Interface system could affect the following types of
monitors. We recommend that you verify the vibration levels in the field after you
install the 3500 Galvanic Isolator Interface system.
