Electrical Safety

Follow basic electrical safety precautions to protect yourself from harm and to protect the storage array from damage:

AC Power Electrical Safety

Caution:

The AC input voltage for each 800W AC power supply is 100 to 240 V. The AC input voltage for each 1600W AC power supply is 200-240 V. Start-up current draw may exceed 8 A.

  • Locate the power switch on the array and the emergency power switch of the room so that you can quickly stop power to the system if an electrical issue occurs.
  • When working with high-voltage components or exposed electrical circuits, have another person who is familiar with emergency power-off locations nearby to switch off the power, if necessary.
  • Use an approved power cord with a grounded plug for the power supply, and plug the power cord into a grounded electrical outlet.
  • When connecting power to power supplies, install the power supply before connecting the power cable to it. When disconnecting power to power supplies, unplug the power cable before removing the power supply.
  • Unplug the power cord before removing a power supply from the chassis.
  • In the rare event that you must shut down an array for maintenance, such as chassis replacement, power down the system and unplug the power cords from all power supplies.

DC Power Electrical Safety

Caution:

This equipment has a connection between the earthed conductor of the DC supply circuit and the earthing conductor. All of the following installation conditions must be met:

  • This equipment shall be connected directly to the DC supply system earthing electrode conductor or to a bonding jumper from an earthing terminal bar or bus to which the DC supply system earthing electrode conductor is connected.
  • This equipment shall be located in the same immediate area (such as adjacent cabinets) as any other equipment that has a connection between the earthed conductor of the same DC supply circuit and the earthing conductor, and also the point of earthing of the DC system. The DC system shall not be earthed elsewhere.
  • The DC supply source shall be located within the same premises as this equipment.
  • Switching or disconnecting devices shall not be in the earthed circuit conductor between the DC source and the point of the connection of the earthing electrode conductor.
