Turning the Power On after an Emergency Shutdown
To restart the enclosure after a power failure or emergency shutdown, follow these steps:
1. After the emergency situation is over or power is restored to the site, turn off all
power switches (see Figure 3-1 on page 28).
Danger:
Severe electrical shock can occur. Never turn on the power to any
equipment when there is evidence of fire, water, or structural damage. If there is
evidence of damage, call the factory or appropriate service organization for
assistance. Depending on the current service agreements, you may need to send
the unit back to the factory for repair/replacement.
2. Check all components and cables for visible damage. Do not power on the enclosure
if you find evidence of damage.
Note: To speed drive spin-up, it is recommended that you start the expansion
enclosures before or at the same time as the controller enclosure.
3. Turn on the power to the enclosures (see Figure 3-1 on page 28).
4. Use TPSSM and the drive fault indicators (see “Checking the Indicator Lights” on
page 34) to check the overall status of the enclosure and its components. Repair any
faults found.
