8. 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.
