Wiring Precautions
This section describes some important safety precautions that you should pay attention to before
proceeding with any installation.
ATTENTION
Be sure to disconnect the power cord before installing or wiring the evaluation board.
ATTENTION
Determine 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.
ATTENTION
Please take care when handling the evaluation boards. When plugged in, the evaluation boards’
internal components generate heat, and consequently the board may feel hot to the touch.
You should also pay attention to the following:
z 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.
Separate paths should be used to route wiring for power and devices. 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 wires sharing similar electrical characteristics may be bundled together.
z Keep input wiring and output wiring separate.
z If power wiring and device wiring paths must cross paths, make sure the wires are
perpendicular at the intersection point.
z All wiring should be clearly labeled.
