Aquamaster Control PCB image
System Earthing
An earth terminal is located within the compartment of the Aquamaster. Connect an earth wire from
the primary electrical supply to the earth terminal.
Input Power Wiring
The Aquamaster requires 240VAC, 40amp
maximum input power to operate the control
logic circuits, low voltage devices and hard
wired socket outlets. This power must be
supplied from a maximum 40amp circuit breaker
with earth leakage protection in accordance
with the wiring rules. It is recommended surge
protection be fitted in areas of unreliable power
supply or prone to lightening strikes.
The mains power cables should utilize the
threaded cable entry point provided on the
bottom plate right hand side of the enclosure
to ensure electrical segregation between low
voltage and extra low voltage cabling.
Wiring 15amp switched relays
The Aquamaster features 2 x 15amp dry contact switching
relays which may be used to operate equipment with an
electrical rating of up to 15amps each. Ideally, a separate
electrical supply with circuit breaker protection should be
connected to each 15amp switching relay numbered 6 & 7
on the PCB.
These power cables should utilize the threaded cable entry
points provided in the side of the enclosure to ensure
electrical segregation between low voltage and extra low
voltage cabling.
