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
1. Place the Master on its back with the display unit facing up and the keypad to the right
2. Remove the two screws from just above the display unit
3. 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
4. Unplug the ribbon power cable from the back of the display unit
5. Set the display unit aside
6. 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)
7. Remove the rectangular knockout near the top of the power supply
8. 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
9. Plug the ribbon cable from the power supply into the display unit
