Main Circuit
• Do not touch the power terminals before the main-circuit capacitor has had time to dis-
charge because high voltage may still remain in the converter and SERVOPACK. Refer
to the following table for the discharge time of main-circuit capacitor.
• When two or more SERVOPACKs are used in combination, use the longest discharge
time of those SERVOPACKs for the main-circuit capacitor.
• First make sure the charge indicator is turned OFF and that the DC-bus (symbol: P and
N) voltage value is correct by using a tester or other device before wiring or starting an
inspection.
