The power supply DC outputs (with the exception of +5VSB) shall be enabled with
an active-low, TTL-compatible signal("PS-ON"). The +5VSB is on whenever the
AC power is present.
. When PS-ON is pulled to TTL low, the DC outputs are to be enabled.
. When PS-ON is pulled to TTL high or open circuited, the DC outputs are
to be disabled. Turn ON/OFF delay ≥1000mS

INFORMATION TO THE USER
This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part
15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in
a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not
installed and used in accordance with the instructions, may cause harmful interference to radio communications.
However, there is no guarantee that interference will not occur in a particular installation. If this equipment does
cause harmful interference to radio or television reception, which can be determined by turning the equipment
off and on, the user is encouraged to try to correct the interference by one more of the following measures:
-. Reorient or relocate the receiving antenna.
-. Increase the separation between the equipment and receiver.
-. Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
-. Consult the dealer or an experienced radio/TV technician for help.
WARNING
Changes or modifications not expressly approved by the manufacturer could void the user’s authority to operate
the equipment.
