Placement Options
Desktop
Place your DA-660/662 on a clean, flat, well-ventilated desktop. For better ventilation, attach the 4 pads from
the desktop kit to the bottom of the unit, and leave some space between the DA-660/662 and other equipment.
Do not place equipment or objects on top of the DA-660/662, as this might damage the computer’s internal
components.
Connecting the Power
The DA-660/662 is designed to be mounted on a standard 19-inch rack. Two L-shaped metal plates are
included as standard accessories with the DA-660/662. Use the enclosed pair of L-shaped metal plates and
screws to fasten your DA-660/662 to the rack cabinet. Two placement options are available. You can either lock
the front or the rear panel of the DA-660/662 to the front of the rack. Each L-shaped plate has 6 holes, leaving
two outer or inner holes open for your convenience.

Device, and Connecting to the Console Port.
Wiring Requirements
ATTENTION
Safety First!
Be sure to disconnect the power cord before installing and/or wiring your DA-660/662.
Wiring Caution!
Calculate the maximum possible current in each power wire and common wire. Observe all electrical codes
dictating the maximum current allowable for each wire size.
If the current goes above the maximum ratings, the wiring could overheat, causing serious damage to your
equipment.
Temperature Caution!
Be careful when handling the DA-660/662. When plugged in, the DA-660/662’s int
ernal components generate
heat, and consequently the outer casing may feel hot to the touch.
You should observe the following common wiring rules:
• Use separate paths to route wiring for power and devices. If power wiring and device wiring paths must
cross, make sure the wires are perpendicular at the intersection point.
NOTE: Do not run signal or communication wiring and power wiring in the same wire conduit. To avoid
interference, wires with different signal characteristics should be routed separately.
• You can use the type of signal transmitted through a wire to determine which wires should be kept separate.
The rule of thumb is that wiring that shares similar electrical characteristics can be bundled together.
• Keep input wiring and output wiring separate.
• Where necessary, it is strongly advised that you label wiring to all devices in the system.
