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.
➢DO NOT open the instrument under any circumstances.

3
Limited warranty
➢
CET Inc. (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.

2.6 Communications Wiring
The PMC-S963-C provides one standard RS-485 port which supports the Modbus RTU protocol. Up to 32 devices
can be connected on a RS-485 bus. The overall length of the RS-485 cable connecting all devices should not
exceed 1200m.
If the master station does not have a RS-485 communications port, a RS-232/RS-485 or USB/RS-485 converter
with optically isolated output and surge protection should be used.
