Wiring Requirements
The following common safety precautions should be observed before installing any electronic device:
•
Power wires and communication/signal wires should be routed through separate paths. If power and
communication/signal wires must cross paths, make sure the wires are perpendicular at the intersection
point.
•
Use the type of signal transmitted through a wire to determine which wires should be bundled together and
which kept separate. The rule of thumb is that wiring that carries similar electrical signals can be bundled
together.
•
When necessary, we strongly advise labeling the wiring for 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 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 rating, 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.
Restricted Access Location
This equipment is intended to be used in Restrict Access Location, like computer room. The access can only be
gained by SERVICE PERSONS or by USERS who have been instructed about the metal chassis of the equipment
is so hot that service persons have to pay special attention or take special protection before touching it.
Further, the access is through the use of key or security identity system. Only authorized by well trained
professional person can access the restrict access location.
External metal parts are hot!! Before touching it, special attention or protection is necessary.
