INTRODUCTION
PowerScout™ Meters
PowerScout meters monitor the voltage, current, power, energy, and many other electrical parameters
on single and three-phase electrical systems. A PowerScout meter uses direct connections to each phase
of the voltage, and uses current transformers to monitor each phase of the current. Information on
energy use, demand, power factor, line frequency, and more are derived from the voltage and current
inputs.
The communications interface to the meters is an RS-485 serial or Ethernet connection (PS3 Plus
Ethernet only) that uses the BACnet Master Slave Token Passing (MS/TP) protocol or Modbus protocol
for sending commands and retrieving data. A separate remote terminal unit (RTU), Data Logger, or
Building Management and Control System is usually connected to the PowerScout to provide data
recording and trend logging plus a human interface or display.
POWERSCOUT™3PLUS/POWERSCOUT™3PLUS ETHERNET
The PowerScout 3 Plus is light-weight and compact enough to mount within an electrical
panel. It is typically used for quick in-and-out monitoring of electrical systems.
Up to 127 PowerScout 3 Plus meters may be connected to a single BACnet client for
monitoring and recording power usage at multiple locations within a single site. Up to 247
meters may be connected to Modbus.
There are two configurable digital pulse output ports on the PS3. The ports can be used to
output kWh, kVARh, or kVAh pulses to external devices, or to toggle on and off to control a
remote device or relay.
POWERSCOUT™24
The PowerScout 24 is capable of reading eight elements at a time and is
mounted near the breakers. It is typically used for long-term monitoring of
electrical systems.
Up to 127 PowerScout 24 meters may be connected to a single BACnet client
for monitoring and recording power usage at multiple locations within a
single site. Up to 30 meters may be connected to Modbus. There are eight
configurable digital pulse output ports on the PS24. The ports can be used to output kWh, kVARh, or
kVAh pulses to external devices, or to toggle on and off to control a remote device or relay. There are
also two digital pulse input ports. Pulse input is used to count, accumulate and scale pulses received
from non-DENT external pulse-initiating meters such as gas, water, or other electrical meters. The
PowerScout 24 can be purchased either in an enclosure (PS24-D) that is UL-listed or as a standalone PC
board (PS24-N) that is UL recognized and must be installed in a user-supplied enclosure.

FIELD INSTALLATION
Mounting a PowerScout™Meter
PowerScout meters must be installed in an approved electrical panel or enclosure using proper
installation practices according to the local electrical codes.
•To mount the PowerScout 3 Plus use the two tabs provided at both ends of the case. Securely
mount the PowerScout near a dedicated circuit disconnect breaker.
The raw board of the PowerScout 24 meter can be mounted to customer-provided standoffs or
placed into a NEMA (National Electrical Manufacturers Association) box. A NEMA-rated box is
available through DENT Instruments. Securely mount the PowerScout meter near a dedicated
circuit disconnect breaker.
WARNING! Remove the meter from all sources of voltage before mounting.

Connecting a PowerScout™ Meter
PowerScout meters have the following connections:
Either a three-wire connector for the RS-485 BACnet/Modbus link or an Ethernet connector.
The PowerScout 3+ has four hardwired voltage leads for connecting to voltage sources (L1, L2,
L3, and Neutral). The PowerScout 24 has the four voltage connections but the leads are not
supplied.
PowerScout meters are self-powered from L1 and L2.
Up to three (PS3 Plus) current transformers (CTs), twenty-four (PS24) current transformers
(CTs).
Digital output ports. The ports can be used to output kWh, kVARh, or kVAh pulses to external
devices, or to toggle on and off to control a remote device or relay.
Completing the Wiring Connections—Ethernet/RS-485, Voltage Leads
and CTs
1) Connect with an Ethernet cable to a computer.
-or-
Connect the RS-485 adapter to the computer using
the USB cable and by inserting each white ferrule
into the appropriate opening on the PowerScout
meter. The red wire inserts in (+), the black wire in
(-) and the green wire in (S).
DID YOU KNOW?The
PowerScout has an internal,
non-user replaceable .5 Amp
fuse protection.

3) Attach the CTs onto the PowerScout connections labeled CT 1, CT 2 and CT 3.
4) Place the CTs on the phase wires of the load to be monitored and corresponding to the phase of the
voltage leads. The CT labeled CT 1 must be placed on L1 phase voltage wire, CT 2 must be on the L2
voltage and CT 3 on the L3 voltage. Refer to PhaseChek™later in this section for information about
the CT LEDs and verifying the CT installation.
5) Connect the PowerScout meter 14 AWG THHN (or
equivalent) wires as close as possible to a
building-installed, dedicated circuit disconnect
breaker. Mark the breaker as the “disconnect” for
the PowerScout. Refer to the wiring diagrams in the
Appendix for specifics of the wiring connections.
Follow local electrical codes during this installation.

Connecting a Communication Cable
High voltage MAY BE PRESENT. Risk of electric shock. Life threatening voltages may be present.
Qualified personnel only.
Haute tension peut être présente. Risque de choc électrique. Tensions dangereuses peuvent
être présentes. Personnel qualifié uniquement.
Communication between a PowerScout meter and a logger is established with a serial RS-485 adapter or
an Ethernet connection. A serial connection (RS-485) is limited in speed while a parallel connection
(Ethernet) is much faster. PowerScout meters are ordered from DENT Instruments based on the type of
desired connection.
NOTE: Installation of a communication cable and the ViewPoint™ software can be completed and tested
with a meter prior to the field installation.
CONNECTING VIA A RS-485 ADAPTER
To complete the connection between the PowerScout meter and the computer, the three wires coming
from the RS-485 adapter are plugged into the PowerScout.
Insert each white ferrule into the appropriate RS-485 connection on the PowerScout. The red wire
inserts in (+), the black wire in (-) and the green wire in GND, Figure II-1.
Verify that the dip switches on the back of the RS-485 adapter are set to: RS-485, Echo Off, 2 Wire, 2
Wire as shown in Figure II-2.
The adapter is ready to be connected to the PowerScout meter.

INSTALLING THE RS-485 ADAPTER TO A COMPUTER
Installation of an RS-485 adapter and the ViewPoint™ software can be completed and tested with a
Modbus meter prior to the field installation.
1) Insert one end of a USB cable into the RS-485 adapter and the other end into a USB port on the
computer.
2) Insert the CD that came with the RS-485 adapter into your computer.
3) The Found New Hardware Wizard window appears.
The window states “This wizard helps you install software for: Model USOPTL4,” and asks “What do
you want the wizard to do?”
4) Select Install the software automatically and click Next.
5) Click Finish when the installation is complete.
6) Remove the CD from your computer.

CONNECTING VIA AN ETHERNET CABLE (POWERSCOUT 3PLUS ONLY)
Connect one end of the Ethernet cable into the PowerScout and the other end into your computer. To
begin communicating via an Ethernet cable you must first set it up within the ViewPoint™ Software that
came with the meter.
PowerScout 3+
1) Select your meter type.
2) Select Ethernet (TCP/IP) to gather information via a network connection. When selected, the
Communications Setup screen changes and an IP Address is required.
3) Select Modbus as your mode of communication.
4) Enter the IP Address for the Ethernet connection of the meter or select one of the previously used
addresses from the drop-down list.
The Scan Network button scans the network for possible meters. The Logger Selection dialog box
displays.
