Please note: when any work is carried out on aset, the following safety must be carried out to ensure continued
electrical safety.
1) Flash Test:
Test at 4kV between the live and neutral of the mains lead joined together and ALL accessible metal points on the
exterior of the set.
2) Insulation Resistance Test:
Test between the live and neutral of the mains lead joined together and ALL accessible metal points on the extericr
of the set to show resistance of at least 4M ohm.
