Electrical notes and legend (cont’d)
GENERAL
a. This drawing is based on IEC symbols.
b. Field wiring must be in accordance with the relevant electrical code and all other applicable codes and specications.
c. All sources of supply shown on this diagram must be taken from one main isolator, not shown or supplied by Quantech.
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 is used for interlock control wiring supplied by external source.
e.
The legend designation depicts component abbreviations. Number prex located, if applicable, on schematic circuit, refers to
system thereon, for example = 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 volts.
The customer must take particular care when deriving the supplies for the voltage free terminals with regard to a common
point of isolation. These circuits when used must be fed through 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
Quantech. The Quantech voltage free contacts are rated at 100 VA. All inductive devices {relays} switch by the Quantech
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 Quantech control panel must 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.

22 Optional compressor manual motors starters (standard on CE units).
23 See sheet 3 of connection diagram for power input options.
24 Alternate connections shown for di󰀨erent two speed motor types.
25 Only tted on systems with a maximum of 4 fans.
26 220/230V units require a separate fuse for units w/4 or more fans per system.
27 Low ambient kit -FSC for fan -MF1 is only tted on systems with less than 4 fans.
