NOTES:
1. UNLESS OTHERWISE NOTED ALL SWITCHES ARE
SHOWN AT 25 C (77 F), AT ATMOSPHERIC
PRESSURE, AT 50% RELATIVE HUMIDITY, WITH ALL
UTILITIES TURNED OFF, AND AFTER A NORMAL
SHUTDOWN HAS OCCURED.
2. DASHED LINES INDICATE RECOMMENDED FIELD
WIRING BY OTHERS. DASHED LINE ENCLOSURES
AND/OR DASHED DEVICE OUTLINES INDICATE
COMPONENETS PROVIDED BY THE FIELD. PHANTOM
LINE ENCLOSURES INDICATE ALTERNATE CIRCUITRY
OR AVAILABLE SALES OPTIONS. SOLID LINES
INDICATE WIRING BY TRANE.
3. NUMBERS ALONG THE RIGHT SIDE OF THE SCHEMATIC
DESIGNATE THE LOCATION OF CONTACTS BY LINE
NUMBER. AN UNDERLINED NUMBER INDICATES A
NORMALLY CLOSED CONTACT. AN OPEN ARROWHEAD
BELOW THE LINE NUMBER POINTING UPWARD INDICATES
A TIMED CONTACT WHICH BEGINS TIMING WHEN
ENERGIZED.
4. ALL FIELD WIRING MUST BE IN ACCORDANCE WITH
THE NATIONAL ELECTRICAL CODE, STATE, AND
LOCAL REQUIREMENTS. OTHER COUNTRIES
APPLICABLE NATIONAL AND/OR LOCAL REQUIREMENTS
SHALL APPLY. FIELD CONDUCTORS SHALL HAVE
INSULATION RATING NOT LESS THAN 600V COPPER
CONDUCTORS ONLY.
