Installing a BigIron RX-4 switch

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, -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.
CAUTION
For the DC input circuit to the system, make sure there is a UL-Listed 30 amp circuit breaker,
minimum -48Vdc, double pole, on the input to the terminal block. The input wiring for connection
to the product should be Listed copper wire, 8 AWG, marked VW-1, and rated minimum 9o C.
CAUTION
For a BigIron RX-32 AC system, use a ground wire of at least 6 American Wire Gauge (AWG). The
ground wire should have an agency-approved crimped connector (provided with the chassis)
attached to one end, with the other end attached to building ground. The connector must be
crimped with the proper tool, allowing it to be connected to both ground screws on the enclosure.
