Supply Power to the Lighting System
When the unit is plugged in, a continuous 115 Volts AC is supplied to the lighting system, making it possible to ener-
gize the lights 100% of the time, even if the door is closed. (See Lighting System ON/OFF). The lighting system
can also be disabled for observance of certain religious days, (See Sabbath Mode). The illustration below shows
normal operation, with 115 Volts AC supplied to the unit. (See Figure 3-15)
