1.1 About This Manual
This manual is intended for the user of the PM130 Powermeter.
The PM130 is a microprocessor-based instrument used for meas-
urement, monitoring, and management of electrical parameters.
This chapter gives an overview of this manual and an introduction
to the PM130.
Chapter 2, Installation, provides instructions for mechanical and
electrical installation.
Chapter 3, Using the Menus, presents the structure of menus for
setup and status viewing.
Chapter 4, Setup Menus, provides instructions for performing
parameter setup via the front panel.
Chapter 5, Data Display, guides you through the display pages.
Chapter 6, Viewing Status Information, tells you how to access
additional status information on the instrument. This information
may be useful during installation.
Technical Specifications for the PM130 are found in the Appendix.
1.2 About The PM130
The PM130 is a compact panel mounted 3-phase AC Powermeter,
specially designed to meet the requirements of users ranging from
electrical panel builders to substation operators. The PM130 is
available in three models: the PM130 for basic voltage, current
and frequency measurements; the PM130P which adds power and
power factor measurements; and the PM130E which adds power
demands and energy measurements. All models are suitable for
mounting on both 4-inch round and 92x92mm square cut-outs.
Features
Display: The front panel features bright LED displays (three
windows, up to 38 pages) with adjustable display update time, and
a LED bar graph showing percentage load with respect to user-
definable nominal (100%) load current. In the common
measurements group (see Chapter 5), Display Auto Scroll is
available with a programmable scroll interval of 2 to 15 seconds.

Chapter 1 Introduction
2
Automatic return to the main screen is available after 30 seconds
of uninterrupted use.
Setup is menu driven, with optional password protection.
Communications are available using an RS-485 standard, with
ASCII/Modbus or ASCII/DNP3.0 protocols. 120 user assignable
registers are available. Transmitter and receiver status are
displayed on the status information page (see Chapter 6).
One multi-purpose relay (optional) is provided for energy pulsing
(KYZ) or alarm and remote control. Up to 16 setpoints can be
assigned to the relay.
Four time operation counters are provided which are operated
and released by user-defined triggers. These are for counting total
generator time or transformer or power line time overload.
External synchronization of the power demand interval is
provided through communications in the PM130E.
Three user-selectable options are provided:
Power calculation mode (P.cAL):
Mode 1: Reactive power calculation (rEAc)
Active power P and reactive power Q are measured
directly and apparent power S = √P2+ Q2
Mode 2: Non-active power calculation (nAct)
Active power is measured directly, and apparent
power S = V ×I (V, I - rms voltage and currents)
and non-active power N = √S2 -P2
Mode 1 is recommended for electrical networks with low
harmonic distortion (voltage THD <5%, current THD <10%);
Mode 2 is recommended for all other cases. (The PM130 does
not measure harmonics; contact your distributor for information on
instruments that provide harmonic measurement).
Energy rollover value (roll – PM130E only)
This option specifies the point at which the energy value rolls
over to zero. For example, if the roll value is 10.E4, then the
energy counter has 4 digits, i.e., energy is displayed up to 9999
kWh (kvarh, kVAh) with resolution 1 kW-hour.
Roll value Maximum Energy Resolution
10.E4 9999 kWh (kvarh, kVAh) 1 kWh (kvarh, kVAh)
10.E5 99999 kWh (kvarh, kVAh) 1 kWh (kvarh, kVAh)
10.E6 999.99 MWh (kvarh, kVAh) 10 kWh (kvarh, kVAh)
10.E7 9999.9 MWh (kvarh, kVAh) 100 kWh (kvarh, kVAh)
10.E8 99999. MWh (Mvarh, MVAh) 1 MWh (Mvarh, MVAh)

Chapter 1 Introduction 3
The roll value may be changed in accordance with the average
load of the power line. For example, if average power equals 400
kW and the counter must reset every 3 months (2160 hours),
then energy during this period equals 864000 (6 digits) and the
roll = 10.E6.
Phase energy calculations mode (Ph.En)
This option is used to enable or disable phase energy calculations.

2.2 Electrical Installation
)Before installation ensure that all incoming power
sources are shut OFF. Failure to observe this practice can
result in serious or even fatal injury and damage to
equipment.
Connections to the PM130 are made via terminals (voltage input,
power supply, communication and optional relay output) and CT
cores located on the rear of the instrument as shown in Figure 2-3.
Note: If your PM130 was not ordered with the optional relay, it will
not have the relay connector.
Figure 2-3 PM130 Connections - Rear View
2.2.1 Power Supply Connection
The power supply can be dedicated-fused, or from a monitored
voltage if it is within the instrument’s power supply range.
Connection to the AC power supply is: Line to terminal L; Neutral
to terminal N.

Chapter 2 Installation 9
2.2.2 Current Inputs
To ensure accurate readings, the input current should not exceed
1.5A RMS for the 1A CT secondary, or 7.5A RMS for the 5A CT
secondary.
The PM130 does not have current terminals. To connect to the
external CT, you must pass the external CT wire through the
instrument CT core (see Figure 2-4).
In the case of a retrofit where each external CT ends with two
wires, pass one wire through the core and connect it to one of the
instrument termination screws; connect the second wire from the
termination screw to the external CT to close the loop. One wire
must pass through the core; observe the arrow which indicates
the current direction (see Figure 2-4).
2.2.3 Ground
Connect the ground PM130 terminals of the power supply and
communication connectors to the switchgear earth ground using
1.5 mm2/14 AWG dedicated wire.
