Operation with Residual Current Devices (RCD)
If an RCD (also referred to as an ELCB or a RCCB) is fitted, the Power Module will operate
without nuisance tripping provided that:
● A type B RCD is used.
● The trip limit of the RCD is 300 mA.
● The neutral of the supply is grounded.
● Only one Power Module is supplied from each RCD.
● The output cables are less than 50 m (164 ft) screened or 100 m (328 ft) unscreened.
If no RCD is used, the touch protection can be achieved by double insulation or by
separating the Power Module from the mains system using a transformer.
