c)It should be free from connection to the terminal blocks but if not gently try to push in an upward
motion on the bottom of the front cover.
d)Now there should be two parts in your possession. You can lay the front enclosure panel down;
you will not need it until re-attaching it to the back enclosure panel once it is mounted. Place in a safe
area where neither side of the panel can be damaged. (Side note: When picking front panel back up
make sure to check that all components inside were not damaged)
2)Mounting the TSTAT7 back plate securely to desired surface:
a)Have the removed back plate in hand; knock out the center of the back plate. You can use the
butt end of the screw driver to do this. The back end once knocked out has no use anymore and can
be thrown out.
b)Insert the wires through the center of the back plate that has just been removed. If necessary,
use a wire stripper to remove about 1/4 of an inch of the plastic insulation from the ends of the wire.
c)Attach the wires to the correct screw terminals that are listed on the back plate. Below is a termi-
nal block that can aid in the connection of the wires. Also you can consult the wiring diagram to make
sure that everything is connected properly, so there are no problems after the front panel enclosure is
put on.
