Maintenance and Inspection
The V700 Series must be inspected on a daily or regular basis so that the func-
tions of the V700 Series can be used in good condition.
The V700 Series consists of semiconductors that last almost indefinitely. The
following malfunctions may, however, result due to the operating environment
and conditions.
1, 2, 3...
1. Element deterioration due to overvoltage or overcurrent.
2. Element deterioration due to continuous stress caused by high ambient
temperature.
3. Connector contact faults or insulation deterioration due to humidity and
dust.
4. Connector contact faults or element corrosion due to corrosive gas.
