2. Guide the free end of a DC power cable, with about

/2 inch of

insulation stripped from the wires, to the terminal block

supplied with the DC system. Clamp the DC leads (positive,

negative, and ground) to the terminal block.

Caution

The connection to DC power consists of three wire leads

(no larger than #12 AWG, fine strand or solid, but

capable of handling at least 10 Amps of current). To

avoid grounds or shorts, exercise care when securing

the wires to the connector.

Note For additional protection if the conditions of the site

call for it, you may wish to also use the chassis ground

point on the rear wall of the unit (the GND connection

with a

/4 x 20 thread located in the lower right corner

of the back panel, as viewed from the rear). This

ground point is to be connected to the equipment rack

or other reliable path to ground.

3. Assemble the clam-shell connector housing around the wires

as shown in the diagram above. Secure a length of Tyrap

around the housing to reinforce the assembly.
