Protection
during
Maintenance
Ensure iBox/iBox Kits are protected from falling debris during maintenance. Small
metallic particles (such as wire clippings) could fall onto circuit boards and damage
or interfere with the safe and reliable operation of the iBox/iBox Kit.
RF
Interference
The iBox/iBox Kit generates radio frequency (RF) energy that can radiate if it is not
installed and used in accordance with the instructions provided in this guide. This RF
energy may cause harmful interference to radio communications or sensitive circuits.
Operating an inadequately shielded iBox or iBox Kit in a residential area may cause
harmful interference, if this happens, you may be liable to correct the interference.
!
Rack Spacing
When mounting multiple iBox/iBox Kits in a rack (or when mounting an iBox/iBox
Kit in a rack with other equipment), verify that there is at least one rack unit (RU) of
space above and below the iBox/iBox Kit, to allow for cooling airflow, and for
routing cables between field equipment and the iBox/iBox Kit (1 RU = 1.75 inches).
Power and
Fusing
• For proper operation, input voltages must be within specified limits. Do not
apply voltages outside this range, since this may lead to premature product
failure.
• Always fuse-protect field sources.
• Always replace fuses with fuses of the same type and rating. Fuse types and
ratings are stated in the product specifications.
Grounding
To ensure voltage transients are properly shunted to ground, you must connect the
iBox’s protective earth terminal to a low-impedance ground point using a braided
cable or heavy solid copper conductor.
When making ground connections, ensure all grounding surfaces are free of dirt,
residue and corrosion. You can use a coating such as Glyptal
®
to protect connections
from oxidation and dirt deposits.
Cable shields should be grounded to either the iBox/iBox Kit ground terminal or to
field equipment, but not to both. Do not ground cable shields at more than one point,
since potential differences between the ground points will result in ground loops and
undesirable noise sources.
Communica-
tion Cables
• Use shielded cables to prevent electromagnetic interference.
• Route all communication cables away from power-carrying cables, and make
these cables as short as possible.
• Prior to start-up, verify the integrity of all communication cables and
connections.
