As shown in Figure 4-4, the junction box is designed to accept wiring from the removable

heater cable as well as wiring from the electrical power source. Different wiring configurations

are shown so that the heater wiring can be correctly connected within the junction box

corresponding to a particular (supply) line voltage, i.e. since the Model 5209-05, 5209-10 and

5209-16 models use T3 lamps rated for 240-volt operation, one could install the heater wiring

so that either 240-volt single- or three-phase supply power could be used.

Heater Thermostat

As stated above, a heater safety thermostat is mounted to the back of the model 5209 reflector

and wired into the 19-pin connector mounted to the heater cover. Wiring for the thermostat is

also integrated within the removable electrical heater cable.

When wired into an appropriately designed power source (i.e. the Model 915 ControlIR Power

Control System – See Appendix for detail), the normally closed thermostat will open upon

reaching an overheat condition (160°F) resulting in an alarm condition to occur at the power

controller. The thermostat will close once the heater cools down to a safe operating

temperature (approximately 140°F).

An alarm condition signal can be configured within the power control system to alert the user

that the alarm condition exists (i.e. signal light, signal horn, etc.). Additionally, the power
