CONNECT POWER SUPPLY WIRING
AND COLD LEAD CONDUCTORS
TO HEATING CONTROLLER
Before proceeding with nal power connection, repeat test of the system as per 2.4.
Prepare for power supply wiring connections as follows
z Ensure the power supply branch circuit has been disconnected and de-energized.
z Prepare the Cold Lead for connection to the heating controller: carefully remove 6" of
the black outer jacket. AVOID DAMAGING THE UNDERLYING COPPER GROUND
BRAID! Separate braid wires from the cold lead conductors and tightly twist braid
strands together into a single stranded conductor (Figure 12a). Connect the ground
wire to the ECB.
z Strip ½" of insulation from each of the cold lead conductors.
z Trim excess length from the power supply wiring as necessary, allowing minimum
of 6" to project from the ECB. Remove ½" of insulation from each of the power supply
conductors. Figure 12bshowsa120Vapplication.In240Vapplications,thecoldlead
has red and black insulated conductors.
z Connect Power Supply Wiring to the heating controller following the associated man-
ufacturer’s instructions.
z Do notenergizethe systemuntilthe mortar/groutmaterials ofthenished oor
have fully cured. This will ensure that the setting of the mortar/grout will not be
compromised by the heat from the cables – refer to the mortar/grout manufacturers’
instructions for cure times.
NOTE: Your system installation may require an electrical inspection at this time. Consult
your local electrical and/or building inspection authorities. When you are ready to ener-
gizeyoursystem,consulttheoperatinginstructionsassociatedwiththespecicheating
controller, such as those provided with EasyHeat’s Warm Tiles Controllers.
Installation of any heating controller and associated wiring must be in accordance with the manufacturer’s instructions and all
applicable national and local electrical codes and ordinances.
The DFT Cable Guide offers some useful hints on how to congure your system to operate with optimal comfort and efciency
(refer to the section entitled, “Operating Tips”).
