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.
AND/OR DASHED DEVICE OUTLINES INDICATE
COMPONENETS PROVIDED BY THE FIELD. PHANTOM
LINE ENCLOSURES INDICATE ALTERNATE CIRCUITRY
OR AVAILABLE SALES OPTIONS.
INDICATE WIRING BY TRANE.
3. NUMBERS ALONG THE RIGHT SIDE OF THE SCHEMATIC
DESIGNATE THE LOCATION OF CONTACTS BY LINE
NUMBER.
NORMALLY CLOSED CONTACT.
BELOW THE LINE NUMBER POINTING UPWARD INDICATES
A TIMED CONTACT WHICH BEGINS TIMING WHEN
ENERGIZED.
4. ALL FIELD WIRING MUST BE IN ACCORDANCE WITH
