jumper (PN 860245) with a
#2 Phillips screwdriver.
Remove the two mounting screws (PN 510720) with a 5/64"
Allen wrench and remove block.
Reassemble the terminal block in the reverse order. Refer to
the electrical schematic for proper installation.
NEUTRAL TERMINAL BLOCK
The neutral terminal block
(PN 860241) is the five-
position block with the
white and blue wires locat-
ed on the left side of the
middle shelf (Fig. 46).
Disconnect all wires and
the 5-position jumper (PN
860245) with a #2 Phillips
screwdriver. Remove the two mounting screws (PN 510720)
with a 5/64" Allen wrench and remove block.
Reassemble the terminal block in the reverse order. Refer to
the electrical schematic for proper installation.
