High-voltage precautions

The power supply in this product contains no user-serviceable parts. There may
be more than one supply in this product. Refer servicing to qualified personnel only.
Do not attempt to modify or use the supplied AC power cord if it is not the exact
type required. A product with more than one power supply always comes with a
separate AC power cord for each supply.
The power button, DOES NOT completely turn off the AC power. Standby power
is still active whenever the system is plugged in. To remove AC power from the
appliance, you must unplug each AC power cord from the outlet or the power source.
The power cord(s) is considered the disconnect device to the main (AC) power.
The socket outlet that the device plugs into should be installed near the equipment
and should be easily accessible.
See "Checking the resistance and voltage"
A high-voltage power supply provides power for the device. Direct or indirect contact
(through damp objects) with a high-voltage power supply (including the main power
in a building) can result in fatal danger.
When installing the AC power supply, follow standard safety regulations.
■
Personnel who install the AC power supply must be qualified to perform high
voltage and AC operations.
Do not wear conductive objects such as a watch, chain, bracelet, or ring during
■
the operation.
Switch off the power supply immediately if you find water in the cabinet or if the
■
rack is damp.
Make sure that the device is kept away from water when being operated in a
■
damp environment.
