WARNING
The Multipoint Power Recorder is for use by
qualified personnel only. Do not install the
Multipoint on a power line unless you are
qualified to do so. High voltages that can cause
burns and lethal shocks are present during power
monitoring.
To assure operator safety: When making
connections to power lines, always start by
connecting the instrument power, which contains
the safety earth ground. Be sure to provide
adequate strain relief for wires going to the
terminal blocks.
Use standard high-voltage, high-current safety
precautions.
Workers who open energized power panels are
required to abide by the instructions of
ANSI/NFPA 70E-1988 [B2] concerning
appropriate protective equipment, as well as
government regulations codified in ASHA CFR
1910 [B3] and 1926 [B4], and in ANSI C2-1990
[B1].
CAUTION
Communications and digital data connections to
the Multipoint Power Recorder must be made
with low voltage shielded computer data cables
and compatible components must be used.

Preface
This guide describes the Multipoint Power Recorder and tells you how
to install it and connect it to power.
After installation you will need to connect it to a computer running
either the Power Recorder System Software or the Scenario software,
and then configure the Multipoint. Configuration tells the Multipoint
the specific type of power to be monitored at the installation location
and sets the initial monitoring intervals and other settings. For details
about configuring the Multipoint Power Recorder, see the Power
Recorder System User Guide or the Scenario User Guide.
Warning Symbols on the Multipoint Power
Recorder
Two warning symbols appear on the Multipoint Power Recorder.
When you see
this symbol It means
There is a risk of electric shock.
This symbol appears adjacent to the
power and voltage measuring terminals.
Attention—consult accompanying
documents (this Multipoint Power Recorder
Installation Guide) for information.
This symbol appears adjacent to:
Voltage measuring terminals (pages 12 and 26)
Communication port (pages 16 and 28)
Current measuring terminals (page 14)
Internal battery (page 40)

Introducing the Multipoint
Power Recorder
The Multipoint Power Recorder is designed for permanent or semi-
permanent installation of a Power Recorder in a non-hostile
environment. The Multipoint provides the same quality and features of
other Reliable Power Meters power recorders at a lower cost.
Lethal voltages are present. In order to ensure
safety the Multipoint Power Recorder must be
installed in a protective enclosure that limits access
to the electrical connections of the device and
requires a tool or key for such access. Multipoint
Power Recorders are not weatherproof. If you need
a weatherproof unit, contact Reliable Power Meters
about obtaining a Power Recorder with a Hostile
Environment Enclosure.
The Multipoint Power Recorder actually contains two units—a Base
Unit, and an Acquisition Unit, as shown on page 2. The base unit can be
installed permanently—bolted to a wall, shelf, or panel—while the
Acquisition Unit is removable to allow for repair or calibration, if
necessary, without having to unwire anything or even turn the power off.
Several different models of base and acquisition units are available.
