Feed the 10-AWG, RTN and –48V wires through the large hole in the face of the terminal
block cover. (See Figure 3-6b.) Feed a sufficient length (approximately 3 inches) of these
two wires away from you, through the terminal block cover.
Attach and tighten the RTN and –48V leads to the terminal block. (See Figure 3-6d.) Verify
that you are connecting the appropriate leads to the correct terminal block posts. The color

Using a nylon cable tie that you provide, fasten the RTN and –48V leads to the terminal
block cover, as shown in Figure 3-6c. Insert the nylon cable tie through the small hole at
the bottom of the terminal block cover and around the two leads.
Bundle the RTN and –48V wires behind the terminal block cover so that the cover fits over
the wires and the terminal block. (See Figure 3-6b.) Take care not to strain the leads on the
terminal block or crimp the wires behind the cover. (See Figure 3-6a.)
