4  Electrical Wiring 
4.1  General 
 
 
4.2  Precautions 
  Fix cables so that cables do not make contact with the pipes (especially on the high pressure side). 
  Secure the electrical wiring with cable ties as shown in Figure 3-1.14 and Figure 3-1.15. So that it does not come in 
contact with the piping, particularly on the high-pressure side.

All  installation  and  wiring  must  be  carried  out  by  competent  and  suitably  qualified,  certified  and  accredited 
professionals and in accordance with all applicable legislation. 
 Electrical systems should be grounded in accordance with all applicable legislation. 
Overcurrent circuit breakers and residual-current circuit breakers (ground fault circuit interrupters) should be 
used in accordance with all applicable legislation. 
Wiring patterns shown in this  data  book  are  general connection  guides  only  and  are  not intended  for,  or  to 
include all details for, any specific installation.   
The  water  piping,  power  wiring  and  communication  wiring  are  typically  run  in  parallel.  However  the 
communication wiring  should  not  be bound  together with  power  wiring.  To  prevent signal interference,  the 
power wiring and communication wiring should not be run in the same conduit. If the power supply is less than 
10A,  a  separation  of  at  least  300mm  between  power  wiring  and  communication  wiring  conduits  should  be 
maintained; if  the  power  supply  is  in  the  range  10A  to  50A  then  a  separation  of  at  least  500mm  should be 
maintained.
