Notes (Cont'd)
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
specications
C. All sources of supply shown on this diagram to be taken from one main isolator, not shown or supplied by
Quantech.
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, black 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 prex 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 volts. 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 Quantech. The voltage free contacts
are rated at 100VA. 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 30v 5ma
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 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.
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. Wiring and components for compressor 3 only tted when unit has 3 compressors on the system. 1-BMP3
is replaced by a link across terminals 134 & 135. 2-BMP3 is replaced by a link across terminals 234 & 235.
3. FHP2 is only tted on QTC3045 And above. When not tted 1-FHP2 is replaced by a link across terminals
132 & 139. 2-FHP2 is replaced by a link across terminals 232 & 239
4. Fitted on units with hot gas bypass option.
5. EMS option is wired as shown
6. This wiring must be used for old display 031-0110-000
7. Network connection point
8. Printer port
9. Remote emergency stop can be wired between terminal l and 5 after removing link
10. Power factor correction accessory. Power factor correction tted to each compressor contactor
11. Not tted on compressors with internal motor protection. For system 1 terminals 132 & 133, 133 & 134 And
134 & 135 are linked. For system 2 terminals 232 & 233, 233 & 234 and 234 & 235 are linked.
12. Only tted on systems with 3 or 4 fans
13. Only tted on systems with 4 fans
14. Only tted on systems with 5 fans
15. Only tted on systems with 6 fans
16. Input switch disconnect or circuit breaker option replaces input terminal block
17. Input switch disconnect & system circuit breaker option replaces input terminal block
18. 115V control circuit requires a 115V supply unless control circuit transformer-T2 & -F3 are tted
19. For optional hydro kit. Heater -EPH is tted and wired as shown. On single pump -KP1, -QMMSP1 and
-MP1 are tted & wired as shown. On two pump hydro kits -KP2, -QMMSP2 & -MP2 are also tted and
wired as shown.
20. Current measurement option wired as shown
21. Only tted on systems with single speed fans
22. Only tted on systems with two speed fans
23. Optional compressor manual motors starters.
24. See sheet 3 of connection diagram for power input options
