When using
DANGER
Remove both power cords before servicing.
NOTE
To provide adequate circuit protection between the DC power supply and the switch, all intermediate wiring and circuitry should be rated to carry a load at least two times the maximum rating for this switch (see “Power Supply” on page 32.)
NOTE
For a DC system, use a grounding wire of at least 18 American Wire Gauge (AWG). The 18 AWG wire should be attached to an
NOTE
Wiring for the power input terminals on the switch are described below. Wiring of the DC power supply terminals depends on the equipment in use on the local site, but should be wired in such a way as to meet the input requirements shown in “DC PLUG CONNECTIONS” on page 16. The wiring should also be color coded according to local standards to ensure that the input power and ground lines can be easily distinguished.
To connect the switch to a power source:
1.First verify that the DC power can provide
2.Prepare two wires for each power source to be used. Use 18 AWG stranded copper wire. Make sure these wires are not plugged into the power source.
3.Use a wire stripper to carefully strip about a half an inch of the outer insulation off the end of each wire, exposing the copper core.
4.Twist the copper wire strands together to form a tight braid. If possible, solder the exposed braid of wire together for better conductivity.
5.Connect the external power feed and power ground/return lines to the DC plug (provided with the switch) as shown in the following figure. The plugs are labeled on the front of the chassis, above the DC power connection block. The
This equipment installation must meet NEC/CEC code requirements. Consult local authorities for regulations.
