WARNING
DISCHARGE TIME
The servo drives and the SAB contain DC-link capacitors
that remain charged for some time after the mains
supply is switched off at the SAB. Failure to wait the
specified time after power has been removed before
performing service or repair work could result in death
or serious injury.
•
To avoid electrical shock, fully disconnect the
SAB from the mains and wait for at least the
time listed in Table 1.3 for the capacitors to fully
discharge before carrying out any maintenance
or repair work on the ISD 510 servo system or
its components.

0–64 servo drives
Table 1.3 Discharge Time
NOTICE
Never connect or disconnect the hybrid cable to or from
the servo drive when the ISD 510 servo system is
connected to mains or auxiliary supply, or when voltage
is still present. Doing so damages the electronic circuitry.
Ensure that the mains supply is disconnected and the
required discharge time for the DC-link capacitors has
elapsed before disconnecting or connecting the hybrid
cables or disconnecting cables from the SAB.
