Grounding Terminal
If necessary, use this terminal to connect the S-4000D chassis to an external grounding
source.
* Never attempt to use the following sources for an external ground connection:
•
Water pipes (may result in shock or electrocution)
•
Gas pipes (may result in fire or explosion)
•
Telephone-line ground or lightning rod (may be dangerous in the event of lightning)
AC INPUT
Connect the supplied power cord here.
Secure the power cord with the cord clamps (p. 9) to prevent accidental disconnection of
the cords.
Air Intake Vents Cooling Fan Exhaust Vents
The S-4000D contains cooling fans that prevent the unit from overheating. The air intake
vents provide fresh air for the cooling fans and the fans expel hot air through these vents.
* Clean away any buildup of dust in the intake port or ventilation port using a vacuum cleaner or the
like.
Rear Panel
Be sure never to block the
cooling fan exhaust vents and air
intake vents. Doing so may cause
the S-4000D to overheat and be
damaged.
