4. Maintenance And Inspection

Preventive maintenance and inspection is required to maintain the ModBus+ option 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, always turn off all power supplies to the inverter unit, and wait at least five minutes
after the inverter's "CHARGE" lamp has gone out.
DANGER!
inverter, or for at least 5 minutes after power to the inverter has been removed. A hazard
exists temporarily for electrical shock even if the source power has been removed.
Inspection Points
•
Check that the wiring terminal screws are not loose. Tighten if necessary.
•
Check that there are no defects in any wire terminal crimp points. Visually check that the crimp
points are not scarred by overheating.
• Visually check the wiring and cables for damage.
•
Clean off any accumulated dust and dirt. Place special emphasis on cleaning the ventilation
ports of the inverter and all installed PCBs. Always keep these areas clean, as adherence of
dust and dirt can cause premature component failure.
•
If use of the inverter unit is discontinued for extended periods of time, turn the power on at
least once every two years and confirm that the unit still functions properly.
•
Do not perform hi-pot tests on the inverter or RS485 option card, as they may damage the
unit's internal components.
Please pay close attention to all periodic inspection points and maintain a good operating
environment.
