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)

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.

Installation Considerations
Before installing your Multipoint Power Recorder, be sure to consider
the following:
1. Location: The Multipoint Power Recorder must be installed
according to applicable electrical codes. When choosing an
installation location, keep in mind that you may need to supply a
suitable enclosure, conduit, and other materials.
2. Instrument Power: The Multipoint Power Recorder requires
single-phase instrument power in addition to the measurement
connections.
3. Location Accessibility: Make sure that you locate the recorder
where connections can be safely made.
4. Power Type: You will need to know the power type in order to
make proper connections.
5. Communications Availability: The Multipoint Power Recorder
requires an Ethernet connection.

BEFORE YOU
CAN USE AN
INSTALLED
MULTIPOINT
In addition to being physically installed at a
facility, the Multipoint Power Recorder also needs
to be
configured to measure and store data about
a particular site and location. For more
information, see “Configuring the Power
Recorder” in the Power Recorder System User Guide
or in the Scenario User Guide.
De-energizing Relevant Power
XSafety First: Make sure that all equipment, wiring, and
connections are de-energized.
Warning: Before connecting the Multipoint Power
Recorder to AC power, potential transformers, or
current transformers, be sure these circuits are de-
energized.

Mounting the Multipoint Base Unit
The Multipoint Base Unit must be mounted to a support adequate to
support its weight (18.5 pounds/8.39 kg).
1. Use the Multipoint Template included in the package to mark
where you need to drill holes on the support panel.
2. Drill the four holes, as marked.
3. Secure the Multipoint Base Unit to the support panel (hardware
not included).

Connecting to the Meter Power Source
Warning: Before connecting the Multipoint Power
Recorder to a power source the ground wire should be
securely screwed to the Safety ground stud.
You can connect to the Multipoint meter power using either AC or
DC. The meter power requires 10-15 volts DC, negative ground, or
100 -240 volts AC. You may connect to both AC and DC at the same
time. No switch settings are required.

To hook up power to the Multipoint Power Recorder
XMake the connection between the power source and the meter
power terminal strip on the Multipoint Base Unit.
For an AC connection,
connect line and neutral, ,
as labeled.
For a DC connection, connect the
positive and negative terminals, as
labeled.
For AC connections, a Clip-On Ferrite Bead (Reliable Power Meter
part number 13-043-0004) is included with the Multipoint Base Unit.
Use of this device will ensure compliance with the Class A limits for
radio noise emissions. It should be snapped over the Safety ground,
AC Neutral, and AC Line wires such that it encloses all three wires
simultaneously, and then positioned within 6 inches (150 mm) of the
power terminal strip on the Multipoint.
For an AC connection power must be provided through a dedicated
UL recognized circuit breaker. The wire used must be UL recognized
with a gauge to match the current rating of the dedicated circuit
breaker.
DC power is limited by an internal 5-ampere fuse that is not user
replaceable.
