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.

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.

Chapter 1 Introduction
This manual explains how to use the PMC-53A-E Ethernet Multifunction Meter. Throughout the manual
the term “meter” generally refers to all models.
This chapter provides an overview of the PMC-53A-E meter and summarizes many of its key features.
1.1 Overview
The PMC-53A-E Ethernet Multifunction Meter is CET’s latest offer for the digital power/energy metering
market. Housed in a standard DIN form factor measuring 96x96x88mm, it is perfectly suited for
industrial, commercial and utility applications requiring direct Ethernet connectivity. The PMC-53A-E
features quality construction, multifunction measurements and a large, backlit, Dot-Matrix LCD that is
easy to navigate and user friendly. Compliance with the IEC 62053-22 Class 0.5S and ANSI C12.20 Class
0.2 Standards, it is a cost effective replacement for analog instrumentation and is capable of displaying
4 measurements at once. It also optionally provides an I4 input for Neutral Current measurement, one
0/4-20mA Analog Input for measuring external transducers signal as well as an Ir Input for Residual
Current measurement. With a standard 100BaseT Ethernet port and a RS485 port supporting multiple
protocols, the PMC-53A-E can be easily integrated into Energy Management Systems as well as Building
and Utility Automation Systems.
The meter can be setup through its Front Panel, Web Interface or our free PMC Setup software. The
meter is also supported by our PecStar® iEMS Integrated Energy Management System. Following is a list
of typical applications for the PMC-53A-E:
Industrial, Commercial and Utility Substation Metering
Building, Factory and Process Automation
Sub-Metering and Cost Allocation
Energy Management and Power Quality Monitoring
Contact CET Technical Support @ Su[email protected] should you require further assistance with
your application.
