Wiring Requirements

The following common safety precautions should be observed before installing any electronic device:

• 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.

• 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.

• When necessary, it is strongly advised that you label wiring to all devices in the system.

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 install

ing 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!

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 models (SP), use Power 1 only;

for dual power models (DP and DPP-T), use both Power 1 and Power 2 for power input installation. Refer to the

following figure for detailed information.
