CAUTION
For the NEBS compliant installation of a PowerConnect B-MLXe Series 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, ensure
the bare copper wire has been cleaned and antioxidant is applied to the bare wire.
