Safety instruction
The CMD 68-54/-104 should only be used for measuring electrical energy
and can not be operated outside the specied 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.

EN
Before opening the meter, the secondary circuits of the current transform-
ers must be short-circuited. In case of a clampable current transformer,
the transformer must be fully disconnected. The resulting high voltage on
the current transformer is extremely dangerous (dangerous to life) and can
destroy the current transformer.
The usual local security and work rules must be observed. The installation
of the meter must be carried out by qualied and trained personnel.
Maintenance
is maintenance free. In case of damagees (for example shipping, incorrect
connection or storage) repairs may only be done by PQ Plus GmbH.
Disclaimer / Liability exclusion
The choice of the CMD 68-54/-104 and determination of the suitability of
the meter type for a particular purpose are solely the responsibility of the
buyer. PQ Plus GmbH takes no responsibility for this.
Data/information in catalogs and data sheets do not promise special prop-
erties, but are determined by experience and measurements.
Liability for damages caused by improper operation/ projecting or malfunc-
tion of the energy meter is excluded. The operator/ project engineer has to
take care that improper operation/ planning and malfunctions can not cause
further damage. For defects or damage caused by improper use of the
CMD 68-54/-104 or by not following the manual, no warranty is given.
