CAUTION:
For the DC input circuit to the system of a NetIron MLX -4, -8, and -16, make sure there is a UL-
Listed 30 amp circuit breaker, minimum -48Vdc, double pole, on the input lugs to the power supply. The input wir-
ing for connection to the product should be Listed copper wire, 8 AWG, marked VW-1, and rated minimum 90o C.
CAUTION:
For the DC input circuit to the system of a NetIron MLX -32 make sure there is a UL-Listed 75 amp
circuit breaker, minimum -48Vdc, double pole, on the input lugs to the power supply. The input wiring for connec-
tion to the product should be Listed copper wire, 4 AWG, marked VW-1, and rated minimum 90o C.
CAUTION:
For a NetIron MLX-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.
CAUTION:
For the NEBS compliant installation of a NetIron MLX -4, -8, -16, and -32 with AC and DC 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. Before crimping the ground wire into the provided ground lug, insure the bare copper wire has been
cleaned and antioxidant is applied to the bare wire.
