GENERAL
a. THIS DRAWING IS BASED ON IEC SYMBOLS.
b.
FIELD WIRING TO BE IN ACCORDANCE WITH THE RELEVANT ELECTRICAL CODE AS WELL AS ALL OTHER
APPLICABLE CODES AND SPECIFICATIONS
c. ALL SOURCES OF SUPPLY SHOWN ON THIS DIAGRAM TO BE TAKEN FROM ONE MAIN ISOLATOR, NOT
SHOWN OR SUPPLIED BY YORK.
d. GREEN AND YELLOW WIRE IS USED FOR EARTH, MULTI-COLOURED CABLE USED FOR LOW VOLTAGE.
RED WIRE USED FOR A.C. CONTROL, BLUE WIRE FOR NEUTRAL, BL
ACK WIRE FOR A.C. AND D.C.
POWER. ORANGE WIRE SHOULD BE USED FOR INTERLOCK CONTROL WIRING SUPPLIED BY EXTERNAL
SOURCE.
e. LEGEND DESIGNATION DEPICTS COMPONENT ABBREVIATIONS. NUMBER PREFIX LOCATED, IF
APPLICABLE, ON SCHEMATIC CIRCUIT, REFERS TO SYSTEM THEREON, E.G.= 1-FHP2 REFERS TO HIGH
PRESSURE CUTOUT NO 2 ON SYSTEM NO 1.
f. ALL WIRING TO CONTROL SECTION VOLTAGE FREE CONTACTS REQUIRES A SUPPLY PROVIDED BY THE
DERIVING THE SUPPLIES
FOR THE VOLTAGE FREE TERMINALS WITH REGARD TO A COMMON POINT OF
ISOLATION. THUS, THESE CIRCUITS WHEN USED MUST BE FED VIA THE COMMON POINT OF ISOLATION
THE VOLTAGE TO THESE CIRCUITS IS REMOVED WHEN THE COMMON POINT OF ISOLATION TO THE UNIT
IS OPENED. THIS COMMON POINT OF ISOLATION IS NOT SUPPLIED BY YORK. THE YORK VOLTAGE
FREE CONTACTS ARE RATED AT 100VA. ALL INDUCTIVE DEVICES {RELAYS} SWITCH BY THE YORK
VOLTAGE FREE CONT
ACTS MUST HAVE THEIR COIL SUPPRESSED USING STANDARD R/C SUPPRESSORS.
g. CUSTOMER VOLTAGE FREE CONTACTS CONNECTED TO TERMINAL 13 MUST BE RATED AT 30V 5ma
NO CONTROLS {RELAYS ETC.} SHOULD BE MOUNTED IN ANY SECTION OF THE CONTROL PANEL.
ADDITIONALLY, CONTROL WIRING NOT CONNECTED TO THE YORK CONTROL PANEL SHOULD NOT BE RUN
THROUGH THE PANEL.
IF THESE PRECAUTIONS ARE NOT FOLLOWED, ELECTRICAL NOISE COULD CAUSE MALFUNCTIONS OR
DAMAG
E TO THE UNIT AND ITS CONTROLS.
