6.  Maintenance and Inspection 
Preventive maintenance and inspection is required to maintain the gateway in 
its optimal condition, and to ensure a long operational lifetime. Depending on 
usage and operating conditions, perform a periodic inspection once every three 
to six months. Before starting inspections, disconnect all power sources. 
Inspection Points
•  Check that the network cable(s) are properly terminated in the terminal 
block(s), and ensure that pluggable terminal blocks are fully seated in their 
headers. Reseat if necessary. 
•  Check that there are no defects in any attached wire terminal crimp points. 
Visually check that the crimp points are not damaged or loose. 
•  Visually check all wiring and cables for damage. Replace as necessary. 
•  Clean off any accumulated dust and dirt. 
•  If use of the gateway is discontinued for extended periods of time, apply 
power at least once every two years and confirm that the unit still functions 
properly. 
•  Do not perform hi-pot tests on the gateway, as they may damage the unit. 
Please pay close attention to all periodic inspection points and maintain a good 
operating environment.
