Maintenance And Inspection - GE VAT200 Quick Start Manual

5.5 Maintenance and Inspection

Inverter doesn't need daily inspection and maintenance.
To ensure long-term reliability, follow the instructions below to perform regular
inspection. Turn the power off and wait for the charge indicator (LED101) to go out
before inspection to avoid potential shock hazard possibly caused by charges resides
in high-capacity capacitors.
(1) Clean up the accumulation of muck inside the inverter.
(2) Check if there are any loose terminal screws and securing screws. Tighten all
loose screws.
(3) Insulation tests
(a) Disconnect all leads connecting VAT200 with external circuit when
performing insulation tests against external circuit.
(b) Internal insulation test should be performed against the main circuit of the
VAT200 body only. Use a high resistance DC 500V meter with insulating
resistance higher than 5MΩ.
Caution! Do not perform this test against the control circuit.
