10. Maintenance & Inspection

Never touch the internal parts.
Failure to obey may result in electrical shock, personal injury and other dangers.
Careful checking and maintenance are essential to ensure that the general-purpose inverter
SVC06 series can operate
correctly with a long service life.
10-1 Precautions on Checking and Maintenance

Capacitors retain a high voltage charge for a while after the power is turned off. Before carrying out
inspection, please firstly make sure that the CHARGE lamp is off, then make sure that the voltage across
terminals P and X is lower than DC30V using a circuit tester.
10-2 Inspection Items

The motor works as expected;

The cooling system is free from any problems (such as abnormal heating);

There is no abnormality at the location of installation; and

There is no abnormal vibration or noise.
Table 10-1 Inspection must be carried out following the periodic inspection list.
