ATTENTION: To avoid an electric shock hazard when servicing the drive, a
means for Lockout/Tagout of an external 120V uninterruptible power supply
must be provided. Or the circuit breaker SW5 must be locked and tagged.
Locking and tagging the common bus precharge disconnect switch SW2 alone
does not provide sufficient protection when servicing the drive.
