DA-681 Series Hardware User’s Manual Hardware Installation
ATTENTION
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.
ATTENTION
Safety First!
Be sure to disconnect the power cord before installing and/or wiring your device.
Electrical Current 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 unit. When the unit is plugged in, the internal components generate
heat, and consequently the outer casing may feel hot to the touch.
Connecting the Power
The DA-681 offers both single power and dual power inputs. Use a screwdriver to remove the
screws. Connect the power cord to the screws and then attach the screws to the unit. For single
power models, use Power 1 only; for dual power models, use both Power 1 and Power 2 for power
input installation. Refer to the following figure for detailed information. It will take about 30 to 60
seconds for your operating system to boot up.
