DC Terminal Connector
Figure 7
The Classic's DC terminal connector is located on the circuit board as shown in figure 17. The connector
will take up to a #4 AWG. #4 AWG THHN when installed in the Classic and MidNite E-Panel is rated for
over 100 amps and is therefore suitable for the highest power available from the Classic 150-SL. After
installing the wires for the last time snap in the blue cover that is included in the parts bag.
Maximum and Minimum Wire Size
The Classic’s Blue DC terminal connector will accept wire from #14-#4 AWG
The Classic’s Aux 1 and 2 terminal connector will accept wire up to #18 AWG
WARNING: Extra fine Stranded wire is actually larger in diameter than standard stranded wire
like THHN therefore #4 extra fine strand (Welding cable) will not fit in the terminal block.
Over Current Protection and Wire Size Requirements
The over current devices, wiring, and installation methods used must conform to all electrical codes
applicable to the location of installation. Wiring needs to be protected with proper strain relief clamps and
or conduit. See page 49 for a breaker and wire size chart.
