15-1 Maintenance and Inspections
For regular maintenance, first stop operation, then turn off the power, and then take off the outer
cover. Even after turning off the power supply, charging voltages remaining in the filter capacitor
require some time to discharge. To avoid danger, operation must not start until the charging indicator
goes off, and you confirm the voltage with a voltmeter to be below the safety value (
≤
25 V
DC
).
