Ground Connection

The ground wire must be 12 to 18 AWG, however, it must be as large or larger than the wire

used for power. The Total Access 1248 must be grounded to a reliable grounding source.

To connect the ground wire, perform the following steps:

1. Connect the ground wire (fitted with a loop terminal end) to the ground lug on the front of

the Total Access 1248 (see Figure 3-4).

2. Clean the surface of the frame ground source and apply an appropriate antioxidant.

3. Connect the other end of the ground wire to the grounded frame.

4. Using an ohmmeter, verify continuity between the ground lug and a known good frame

ground. The reading should be less than 1 ohm.
