Connecting the System Ground

A working ground GND is installed on the back of
DGS-6604. GND should be directly connected
to the ground bar of the equipment room. If a
digital grounding bar and an analog grounding bar
exist in the equipment room, the GND should be
connected to the digital bar.

Precautions.
The sectional area of the grounding cable (min. of
18AWG) should be selected to safely conduct the
maximum possible current. Use insulated cables
of good conductivity.
• Do not use bare wire.
• The grounding resistance for combined
grounding should be less than 1 Ohm (Ω).
Simple Grounding Steps
• Unfasten the nut on the rear grounding post of
the equipment.
• Affix the terminal of the grounding cable to the
grounding pole.
• Fasten the nut back on the grounding post.
• Connect the other end of the grounding cable
to a suitable grounding bar.
Installing the Air Filter of the DGS-6600
Series Chassis Switch
On the back of the chassis on the edge of the
right-side is a vertical slot where the air filter
can be fitted. Slide in a cleaned or new air filter
into the slot as per the following diagram. Then
screw the two thumb/Phillips screws (see the
diagram arrows) to secure the air filter into the
chassis. With the air filter installed screw-in two
