9. Connect the wire to your DC power source, making sure to connect the -48V cable to the 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
Make sure that the power source circuits are properly grounded, then use the power cord
supplied with the device to connect it to the power source.
NOTE
Ensure that the DC return is isolated from the chassis ground (DC-I) when connections to the power
supply are made.
CAUTION
For a DC system, use a grounding wire of at least 6 American Wire Gauge (AWG). The 6
AWG wire should be attached to an agency-approved crimp connector crimped with the
proper tool. The crimp connector should allow for securement to both ground screws on the
enclosure. For the Ground lug, use UL listed Panduit crimp connector, P/N LCD6-10A, and
two 10-32, PPH, screws to secure crimp connector to chassis. Grounding position is located
on the side of the chassis adjacent ground symbol.
