Step 5
Disconnect the DC-input cables from the terminal block (see Figure 4-20) in this order:
• Positive (+) source DC cable from the +VE-1 terminal block post
• Negative (-) source DC cable from the –VE-1 terminal block post
Note
If you have a second pair of source DC cables attached to the VE-2 terminal block posts, you
need to remove the second positive (+) and negative (–) source DC cables, in that order, before
you remove the ground cable.
• Ground cable from the ground terminal posts
Save the 1/4-20 nut and the split-ring washer from each terminal block post and set them aside.
Warning When installing the unit, always make the ground connection first and disconnect it last. Statement 42
