e. Optional Remote Control (K775)
This control is included as part of the "NL Option".
Connect it to the "NL Option" box per instructions shipped
with the option. (Not required with the NA-3, NA-5, LT-7 or
LT-56.)
It can be purchased separately when the DC-1500 is used
for other applications.
To install, turn the power off. Remove the screw and lift
the hinged door on the front of the control panel to expose
the terminal strips. Connect the numbered leads to the
appropriate terminals — 75 to 75, etc — on the terminal
strip and the green lead to the stud marked with the sym-
bol . Attach the control cord to the panel at the right
of the terminal strip using a suitable clamp. Close the door
and replace the screw. The Remote Control cord can be
lengthened to any length by properly splicing an appropri-
ate four conductor rubber-covered cable to the standard
25' cord before connecting to the DC-1500 terminal strip.
