Declaration of Conformity
Conditions
The meters are permitted a worst case error of 1% of A/D range during electro-magnetic
disturbance, and must recover automatically when disturbance ceases without the need for human
intervention, such as resetting, power-down etc.
Note: RF interference in the range 20MHz to 75MHz, with an amplitude greater than 8V on the
power cables may cause the display to show “Err” . This effect will cease when the interference
is removed. This effect may be cured by adding clip-on ferrite cores around the power cable, close
to the display.
The meters covered by this certificate must be installed in adherence to the following conditions :-
Signal cabling shall be routed separately to power carrying cabling (includes relay output wiring)
All signal cabling shall be screened. The screen shall only be terminated to the power earth terminal
