10 Maintenance, Decommissioning, and Disposal

WARNING
HIGH VOLTAGE
Potentially lethal voltage is present on the connectors.
Before working on the power connectors (disconnecting
or connecting the cable), disconnect the SAB from the
mains and wait for the discharge time to elapse.
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 10.1 for the capacitors to
fully discharge before carrying out any
maintenance or repair work on the ISD 510
servo system or its components.
