1. Attach DIN Rail
Attach a section of T35 DIN rail within a suitable UL-approved
enclosure.
▪Leave enough clearance for voltage, CT, and
communications wires to be routed within enclosure.
▪UL-approved enclosure is customer supplied.
13. Remove HV Cover

4. Re-attach HV Cover
WARNING: RISK OF ELECTRIC SHOCK. DO NOT
ENERGIZE METER WITH VOLTAGE COVER REMOVED.
FOLLOW ALL STATE AND FEDERAL ELECTRICAL
CODES.
▪Using 14 AWG THHN, 600VAC rated wire, connect the
voltage leads (L1, L2, L3, and N) as necessary to the
meter through a dedicated disconnect or circuit breaker.
DO NOT EXCEED 346V L-N or 600V L-L.
▪Mark the circuit breaker as “PowerScout Meter”

WIRING
iThe PowerScout HD Meter uses the Neutral terminal as a voltage reference. For
systems without a neutral conductor, connect a wire from the N terminal to ground.
iThe PowerScout HD Meter is internally powered through
the voltage between L1 and L2. For Single Phase
installations, where no L2 exists, connect a jumper from N
to L2. This connection provides power to the meter while
maintaining Neutral as the metering voltage reference. NL1 L2 L3
HIGH VOLTAGE MAY BE PRESENT. RISK OF ELECTRIC SHOCK. LIFE THREATENING
VOLTAGE MAY BE PRESENT. QUALIFIED PERSONNEL ONLY.
iThese diagrams show the wiring configuration for the Service Types available in the
Service drop-down list under “Meter Setup;
Service ” in ViewPoint HD Software.

CURRENT TRANSFORMER BASICS
To ensure safety and maintain UL listings, use only CTs provided by DENT
Instruments.
▪Do not use on services greater than 600VAC
▪CTs are 333.3 mV (1/3 V) output voltage, or DENT RōCoil
▪Select CTs of appropriate current range for the circuit (5-120% of CT
rating recommended)
▪Ensure arrow points towards load (or as instructed by CT label)
▪Place CT on first conductor of voltage reference. Example: for L1-L2
circuits without neutral, place CT on L1
▪Observe wiring color and polarity: For millivolt CTs, the white wire is (+)
and the black wire is (-). For RōCoils, the white is (+), brown is (-), and the
bare, shield wire connects to the terminal marked “S”
The PowerScout 3 HD is available in two configurations. The DIN-Rail Mount Enclosure is to be
mounted in a UL-approved electrical enclosure while the Wall Mount Enclosure is ready to be
mounted on the wall next to an electrical panel and does not require an additional enclosure.

WARNING
▪RISK OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH. CAREFULLY READ AND
FOLLOW INSTRUCTIONS.
▪THIS METER MAY CONTAIN LIFE THREATENING VOLTAGES. RISK OF ELECTRIC
SHOCK. QUALIFIED PERSONNEL ONLY. USER MUST DISCONNECT ALL HIGH VOLTAGE
WIRING BEFORE SERVICING THE METER WITH THE HIGH VOLTAGE COVER REMOVED.
▪TO AVOID FIRE, SHOCK, OR DEATH, TURN OFF ALL POWER SUPPLYING EQUIPMENT
BEFORE WORKING ON OR INSIDE THE EQUIPMENT. USE PROPERLY RATED VOLTAGE
SENSING DEVICE TO CONFIRM POWER IS OFF.
▪FOLLOW SAFE ELECTRICAL WORK PRACTICES. FOLLOW ALL APPLICABLE LOCAL
ELECTRICAL CODES.
▪THIS EQUIPMENT MUST BE INSTALLED AND SERVICED BY QUALIFIED ELECTRICAL
PERSONNEL WITH THE REQUISITE KNOWLEDGE, TRAINING, AND EXPERIENCE
RELATED TO THE INSTALLATION AND OPERATION OF THIS EQUIPMENT.
▪PRODUCT MAY USE MULTIPLE VOLTAGE/POWER SOURCES. BE SURE ALL SOURCES
OF POWER HAVE BEEN DISCONNECTED BEFORE SERVICING.
▪DO NOT DEPEND ON THIS PRODUCT FOR VOLTAGE INDICATION.
DO NOT EXCEED 346V Line-to-Neutral or 600V Line-to-Line. This meter is equipped to
monitor loads up to 346V L-N. Exceeding this voltage will cause damage to the meter
and danger to the user. Always use a Potential Transformer (PT) for voltages in excess
of 346V L-N or 600V L-L. The PowerScout HD is a 600 Volt Over Voltage Category III
device.

i
1. Connect a powered, or unpowered, PowerScout meter to a USB port of your computer
with a USB A to USB C cable (provided). [Note: The PC will power the meter for setup even
without AC mains power connected.]
2. Launch the ViewPoint HD application and, when prompted, click “Connect over USB”
3. The meter will now be communicating with the PC
4. Use ViewPoint HD to configure the meter and view real-time data to verify the installation is
wired correctly
SETUP THE METER WITH A PC
The meter can also be setup without using ViewPoint HD and instead using a web
browser. Plug in the USB cable and set the browser to 169.254.1.5.

NAVIGATING THE METER’S DISPLAY
USING THE LCD SCREEN
The PowerScout 3 HD features a navigation thumb wheel which allows the user to scroll up or
down and select menu options by pressing the thumb wheel. While the user interface allows for
checking real time values, it does not allow for meter configuration. ViewPoint HD is the required
configuration tool for the PowerScout 3 HD.
