DANGER
Failure to observe the following instructions may result in severe injury or
death and/or equipment damage.
Installation, operation and maintenance of the meter should only be
performed by qualified, competent personnel that have the appropriate
training and experience with high voltage and current devices. The meter
must be installed in accordance with all local and national electrical codes.
Ensure that all incoming AC power and other power sources are turned OFF
before performing any work on the meter.
Before connecting the meter to the power source, check the label on top of
the meter to ensure that it is equipped with the appropriate power supply,
and the correct voltage and current input specifications for your application.
During normal operation of the meter, hazardous voltages are present on its
terminal strips and throughout the connected potential transformers (PT)
and current transformers (CT). PT and CT secondary circuits are capable of
generating lethal voltages and currents with their primary circuits energized.
Follow standard safety precautions while performing any installation or
service work (i.e. removing PT fuses, shorting CT secondaries, etc.).
Do not use the meter for primary protection functions where failure of the
device can cause fire, injury or death. The meter should only be used for
shadow protection if needed.
Under no circumstances should the meter be connected to a power source if
it is damaged.
To prevent potential fire or shock hazard, do not expose the meter to rain or
moisture.
Setup procedures must be performed only by qualified personnel familiar
with the instrument and its associated electrical equipment.

Limited warranty
Ceiec Electric Technology (CET) offers the customer a minimum of 12-month
functional warranty on the meter for faulty parts or workmanship from the
date of dispatch from the distributor. This warranty is on a return to factory
for repair basis.
CET does not accept liability for any damage caused by meter malfunctions.
CET accepts no responsibility for the suitability of the meter to the application
for which it was purchased.
Failure to install, set up or operate the meter according to the instructions
herein will void the warranty.
Only CET’s duly authorized representative may open your meter. The unit
should only be opened in a fully anti-static environment. Failure to do so may
damage the electronic components and will void the warranty.
