DESCRIPTION
CAUTION! Measuring the power supply voltages
require the control power to be energized. Extreme
care must be observed when taking any readings, as
120 VAC is present within the power supply.
The Remote panel power supply is mounted on the
inside at the top of the panel, as shown at the bottom
of this page. A three-pin connector provides 120 VAC
power to the supply, and a six-pin connector delivers
DC power out of the supply. These connections are of
a push-on multiple contact connector type. This power
supply is not adjustable.

MAINTENANCE
EVAPORATOR REMOTE PANEL POWER
The Evaporator Remote Panel utilizes the +5 VDC, +12
VDC and – 12 VDC voltages from its power supply. To
perform measurements on the power supply voltages,
use a reliable, calibrated Digital Volt Meter (DVM). The
DVM should be accurate to 1/100 of a volt DC. Turn the
control power switch to ON.
Measure the voltages on the power supply at the DC
output connector as shown below.
