Power Filter
The digital controller can be adversely affected by EMI and power spikes. A power
filter may be required if the supply to the equipment is unstable (e.g. frequent power
cuts), shared by equipment which generates high levels of EMI (e.g. inverters, IT
equipment etc.) or is fitted with a backup generator.
If required, a power filter can be purchased separately using product code FC100.
The power filter must be connected between the transformer and the digital controller, on the
12VAC line, as shown in the diagram below:
Because the filter is installed on the secondary side of the transformer, the polarity of the
connections does not matter.
For the filter to function correctly, the “PE LINE” terminal must be connected to the
chassis common earth point
