Product Disposal Statement

Customers and third parties, who are not member states of the European Union, who are 

in control of the product at the end of its life or at the end of its use, are solely 

responsible for the proper disposal of the product. No person, firm, corporation, 

association or agency that is in control of product shall dispose of it in a manner that is

1. Receiving and Handling Instructions 

This will be a short overview of the entire section. 

1.1 Receiving Inspection 

Visually inspect the system for obvious shipping damage. If you detect shipping 

damage, file a claim with the carrier and submit a copy to Bently Nevada, LLC. 

1.2 Handling and Storage Considerations 

Proper handling and storing of printed circuit boards is extremely critical. Circuit 

boards contain devices that are susceptible to damage when exposed to 

electrostatic charges. Damage caused by obvious mishandling of the board will 

void the warranty. To avoid damage, observe the following precautions in the 

order given. 

Application Advisory 

Machinery protection will be lost when 

you remove all power from the rack. 

• Do not discharge static electricity onto the circuit board. Avoid tools or 

procedures that would subject the circuit board to static damage. 

Some possible causes of static damage include ungrounded soldering 

irons, nonconductive plastics, and similar materials. 

• Use a suitable grounding strap (such as 3M Velostat® No. 2060) to 

ground yourself before handling or performing maintenance on a 

printed circuit board. 

• Transport and store circuit boards in electrically conductive bags or 

foil. 

• Use extra caution during dry weather. Relative humidity less than 30% 

tends to multiply the accumulation of static charges on any surface. 

When performed properly, you may remove modules from or install modules into 

the rack while power is applied to the rack. Refer to << Section reference to 

“Module Installation in section 4 >> for the proper procedure. 

2. General Information 

Monitoring and computerized vibration information systems provide the 

information you need to assess the mechanical condition of rotating and 

reciprocating machinery. These systems continuously measure and monitor 

various supervisory parameters and provide crucial information for early 

identification of machinery problems such as imbalance, misalignment, shaft 

crack, and bearing failures. As such, these systems are an efficient and effective

means of satisfying plant management, engineering, and maintenance concerns 

for: 

• Increasing plant safety by minimizing the occurrence of hazardous 

conditions or catastrophic failures. 

• Improving product quality by minimizing process variances caused by 

improperly operating equipment. 

• Maximizing plant availability by servicing only those machines that 

require it and providing more efficient turnarounds. 

• Reducing plant operating costs by minimizing unplanned shutdowns 

and by making more efficient use of maintenance resources. 

For protection of critical machinery, we highly recommend that you permanently
