SELV Compliance
Safety status of I/O connections comply to SELV
requirements.
Power Cord Connection
Caution – Sun products are designed to work
with power systems having a grounded
neutral (grounded return for DC-powered
products). To reduce the risk of electric shock,
do not plug Sun products into any other type
of power system. Contact your facilities
manager or a qualified electrician if you are
not sure what type of power is supplied to
your building.
Caution – Not all power cords have the same
current ratings. Do not use the power cord
provided with your equipment for any other
products or use. Household extension cords
do not have overload protection and are not
meant for use with computer systems. Do not
use household extension cords with your Sun
product.
The following caution applies only to devices with a
Standby power switch:
Caution – The power switch of this product
functions as a standby type device only. The
power cord serves as the primary disconnect
device for the system. Be sure to plug the
power cord into a grounded power outlet that
is nearby the system and is readily accessible.
Do not connect the power cord when the
power supply has been removed from the
system chassis.

The following caution applies only to devices with multiple
power cords:
Caution – For products with multiple power
cords, all power cords must be disconnected
to completely remove power from the system.
DC-Powered Equipment Requirements
Caution – This equipment is designed to
permit the connection of the earthed
conductor of the DC supply circuit to the
earthing conductor at the equipment.
If this DC connection is made, all of the following
conditions must be met:
• This equipment shall be connected to 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 is to be located within the same
premises as the equipment.
• Switching or disconnecting devices shall not be in the
earthed circuit conductor between the DC source and the
point of connection of the earthing electrode conductor.
