Safety instruction
The CMD 68-54/-104 should only be used for measuring electrical energy
and can not be operated outside the specified technical data.
When installing or replacing the meter, the conductors, to which the meter
is connected, have to be dead (power/ voltage off).
Touching live components (voltage or power) is dangerous! Therefore, the
appropriate fuses are to be removed and secured as to make it impossible
for 3rd parties to replace them without the knowledge of the technician
handling the meter.
