Power Cables; Minimum Requirements And Guidelines - SMART Board 4000 Series Installation Best Practices

CHAPTER 5
CABLES AND CONNECTORS
unavoidable, make sure the cable's connector is rated to withstand them.
Use cable ties to secure cables or groups of cables that don't need to be frequently
l
connected and disconnected. This provides the cables with some strain relief and reduces
the risk of damage. If cables need to be connected and disconnected frequently, leave
additional length on the cable to allow for easy connecting and disconnecting of the cable.
CAUTION
Securing the cable ties too tightly can damage the cables.
Reduce the risk of ground loops by using the same power source (such as a power bar) for all
l
devices. Ground loops can cause noise, humming and interference with audio or video
systems.
If possible, run extra, known-working cables through a conduit during installation. It's less
l
expensive to include spare cables than to install a replacement later. Otherwise, make sure
you have an extra set of cables that have been tested and are known to work properly. These
will be helpful if you need to troubleshoot the installation.

Power cables

Power cables can be grounded (three-pronged) or ungrounded (two-pronged). Grounded power
cables limit the buildup of static electricity, reducing the chances of electric shock and damage to
audio systems and other sensitive equipment.
SMART products feature a standard International Electrical Commission (IEC) interface and provide
certified, country-specific power cables. SMART recommends that you always use the power
cable provided with the SMART product because the cable has been appropriately sized for the
SMART product. However, if you ever need to replace a power cable, use the following minimum
requirements and guidelines.

Minimum requirements and guidelines

Use only power cables that meet the following requirements:

Details
Power standards vary among regions, and you'll need to use a power
cable that supports your region's voltages and frequencies. Although
you can use adapters to make power cables compatible with local
power sources, first verify that the adapter can handle the necessary
voltage conversion.
