negative terminal on the power supply and the 0V cable to the positive terminal as marked on
the power supply.
The equipment installation must meet NEC/CEC code requirements. Consult local authorities for
regulations.
DANGER
DC return shall be isolated from the chassis ground (DC-I) when connections to the power supply
are made.
CAUTION
For the NEBS compliant installation of a NetIron CES or NetIron CER 2000 Series devices 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 grounded to either a common bonding network or an isolated bonding
network. 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.
