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.

Caution
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.
