Rack Mount
The LTR8-512 and LTR8-512M come with two L-shaped brackets (optional on the
LTR4-512) so you can install your Master in a standard 19-inch rack
To install the Master in a 19-inch rack
Place the Master on its back with the display unit facing up and the keypad to the right
Remove the two screws from just above the display unit
Lift the display unit up and away from you. Note that two rivets at the bottom of the
cover prevent you from lifting it straight up
Unplug the ribbon power cable from the back of the display unit
Set the display unit aside
Detach the display unit from the wall mount cover by removing the 4 screws on the back
of the display unit (IMPORTANT: These screws are the correct length so they do not
interfere with the circuit board inside the display unit. Using any other screws voids any
warranty)
Remove the rectangular knockout near the top of the power supply
Using the 4 screws that you removed from the display unit, attach the display unit to the
side of the power supply. You can fit a #1 Philips screwdriver with an 8 inch blade
through the holes opposite the 4 screw holes
Plug the ribbon cable from the power supply into the display unit
Remove the two screws from the side of the display unit
