ELECTRICAL NOTES AND LEGEND (CONT’D)
035-21966-101 REV. Y
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-colored cable used for low voltage. Red wire used for AC Control, blue wire for
neutral, black wire for AC and DC 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 customer maximum voltage 240 V. The
customer must take particular care when 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 100 VA. All inductive devices {relays} switch by the YORK voltage free contacts
must have their coil suppressed using standard R/C suppressors.
g.
Customer voltage free contacts connected to terminal 13 must be rated at 30 V 5 mA.
h.
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 damage to the unit and its controls.
I.
120/14.3 - (Signal IN/OUT) i.e. 120 is wire # and 14.3 refers to SHT. 14 column 3.
NOTES
1
Refer to installation commissioning operation and maintenance manual for customer connections and customer connection
notes, non compliance to these instructions will invalidate unit warranty.
2
