Installation precautions
2
DANGER
If the installation requires a different power cord than the one supplied with the device, make
sure you use a power cord displaying the mark of the safety agency that defines the regulations
for power cords in your country. The mark is your assurance that the power cord can be used
safely with the device.
DANGER
Make sure the rack or cabinet housing the device is adequately secured to prevent it from
becoming unstable or falling over.
DANGER
Mount the devices you install in a rack or cabinet as low as possible. Place the heaviest device at
the bottom and progressively place lighter devices above.
CAUTION
Ensure that the device does not overload the power circuits, wiring, and over-current protection.
To determine the possibility of overloading the supply circuits, add the ampere (amp) ratings of all
devices installed on the same circuit as the device. Compare this total with the rating limit for the
circuit. The maximum ampere ratings are usually printed on the devices near the input power
connectors.
CAUTION
BigIron RX-4, -8, and -16 devices with DC power sources are intended for installation in restricted
access areas only. A restricted access area is where access can be gained only by service
personnel through the use of a special tool, lock and key, or other means of security, and is
controlled by the authority responsible for the location.
CAUTION
For a DC system, the gauge of wire will be determined by the power source as well as the power
supply draw (refer to Table 9). Use a grounding wire of at least 6 American Wire Gauge (AWG). The
AWG wire should be attached to an agency-approved crimp connector (provided on the BigIron RX
Series chassis), crimped with the proper tool. The single crimp connector should allow for
securement to both ground screws on the enclosure. For BigIron RX-16, and -8, and -4, use a
grounding wire of at least 6 AWG. For the grounding lug, use UL-listed Panduit crimp connector,
P/N LCD6-10A, and two 10-32, PPH screws to secure the crimp connector to chassis. The
grounding position is located on the side of chassis, adjacent ground symbol.
