2. Shut off power to the DC supply leads.
3. Strip the insulation back approximately 5/16 inch (8mm) from the end of each lead.

on the DNX-11 chassis).

6. Insert the “earth” lead into the earth terminal clamp on the power terminal block and tighten
the clamp screw using a small flat screwdriver (see Figure 11).
