6.3 Precautions for replacing Printed Circuit Board
When the printed board VFC61 is replaced with a spare board, input the previously-used func-
tion set values from the console.
6.4 Disposal

and ordinances.
Request to distributors:
If you deliver your product incorporating with this inverter equipment, supply this manual to the
end user. In case you change the data of inverter set at the factory, inform end user of that
details.
6.2 Insulation resistance test
(1) Clean all parts of the inverter, disconnect
all wires, and short circuit the terminals
of the terminal block TB1 on the main
printedcircuit board. Use a 500VDC
megger for insulation resistance test.
(Do not attempt an insulation resistance
test at the terminals of the control cir
cuit.)
(2) On completion of preparation, measure
insulation resistance between the termi
nals and GND terminal of TB1 on the
main printed circuit board.
(3) On completion of testing, remove the
shorting wire and connect all connectors
with care not to miss them. If the power
is turned on with some connectors
improperly connected, parts may bedam
aged.
