Remark:
The diameter selections of these preceding cables refer to allowable carrying capacity when
no-armored cables 0.6/1KV PVC with three or four-cores, insulation and PVC jacket lay the continuous
charge in air. Since different manufacturer with different models, qualities, laid situation and wiring distance
ect., the allowable carrying capacity of the cable will be got different influence. For example, if the wiring
length is very long, selecting the bigger model should be considered and the circuit voltage down should be
confirmed at the same time. So it is suggest that selecting cable should accord to the professional
electrician’s guidance and refer to the cable manufacturer’s technical manuals. The preceding list is only for
reference.
(3) The color requirement of wirings
Single-phased power wiring adopts the red wiring commonly, but the green, blue and yellow one also can be
used.
Three phase wirings (A, B, C) of the three-phased power wiring should use red, yellow and green in file.
5. Wiring connection of water flow switch
(1) The control wiring connection of water flow switch
The control wiring of water flow switch (prepared by customer) should be connected to main unit’s W1, W2
terminals on the PCB box. The following diagram and specification are for the water flow switch
WFS-1001-H produced by HONEYWELL and only be used for reference.
(2) Specification
Working pressure 10 bar Touch point life 100 million periods
Compression resistance 10.5 bar Ripple life 50 million periods
