INSTALLATION SEQUENCE
The following section illustrates the PS12HD model. The PS48HD components are slightly different but
follow the same procedure.
STEP 1) Remove top cover screws (4x) and high voltage cover screws (2x) – provided
STEP 2) Locate, mark, and drill wall mounting points (2x–6x—user supplied)
The plastic enclosure itself can be used as a template for marking the drill locations on the wall.
If the meter is not available for use as a drill template, a drawing indicating the spacing between mounting
holes can be found in the appendix. The centerline holes are intended for fastening to wall studs. If hollow
wall fasteners are used, the outer 4 mounting points are recommended.

WIRING EXAMPLES
Wiring the PSHD Meter in a 3-wire, Split ɸService Panel
High voltage MAY BE PRESENT. Risk of electric shock. Life threatening voltages may be
present. Qualified personnel only.
Note: Current and voltage inputs must be installed “in phase” for accurate readings (for
example: CT1 on Line 1, CT2 on Line 2
, etc.). Orientation is critical. Ensure that all the CTs are
properly oriented with the line and load as marked.
Failure to install CTs in the correct
orientation and on the correct phase will lead to inaccurate meter readings.

•Single Phase L1-N or L2-N 110 VAC: Lighting, Appliance, Living Zone

Illustrating the intended wiring configuration for each of the Service Types
available in the Service drop-down list under “Meter Setup”
Note: The PSHD Meter Series uses the “Neutral” Terminal as a voltage reference. For systems
without a neutral conductor, DENT Instruments suggests connecting a ground wire to
this
terminal. If the neutral terminal is left open, L
-L measurements will be accurate, but L-N
measurements may not be symmetric. If a ground wire is connected to the Neutral terminal,
<2 mA will flow into the ground wire.

WIRING CURRENT SENSORS TO THE PSHD METER
The image below is the counterpart to the service panel illustration and indicates how to connect CTs to
the PSHD meter for each service type. For service types that are not specifically listed, it is
recommended to choose “single phase” service and configure each channel individually. Three phase
loads are illustrated on the left and split phase loads on the right as an example only. Elements are fully
interchangeable on the meter.

COMMUNICATION VERIFICATION
Verification includes confirmation of BOTH the physical interface settings (Serial or Ethernet)
and the protocol (Modbus or BACnet) settings.
The LCD User Interface can be used to quickly confirm the settings required for each combination of
interface and protocol. The interface is intuitive and groups together commonly associated registers. The
complete interface is presented in Appendix A as a navigational map. Arrows indicate how to move from
one menu display to the next. A Reverse Contrast entry in the documentation indicates the active menu
item in a list which corresponds to a blinking character in the physical LCD. The ENTER button is used to
select a property and up / down buttons are used to select among the values supported by the meter.
Note that changes to the meter configuration are limited to the communication interface using the LCD.
If additional changes (such as CT type) are required, they must be made using a software interface.
Example LCD Navigation
VIEWPOINT HD /PSHD WEB APP
If your PSHD model does not include the LCD User Interface, or if you prefer to verify the installation using
software, then verification is facilitated through the ViewPoint HD PC application or the PSHD Web App,
which share a common design. Refer to the section on Configuration Details for an overview and list of
instructional videos for ViewPoint HD or the PSHD Web App.

OTHER FEATURES
Pulse Inputs
PS12HD meters are equipped with 4 pulse inputs and PS48HD meters are equipped with 2 pulse inputs.
Pulse counting supports accumulation of consumption data from any external meter using a dry contact
(Form A Relay) or open collector outputs. The PSHD pulse inputs are compatible with “low speed” meters.
The pulse duration must exceed 50 mS in both the logic low and high state allowing for a maximum input
frequency of 10 Hz.
Pulse scaling, resetting and accumulated values are accessed through registers and are “system” in
scope. Refer to the register list, ViewPoint HD, or videos for more information.
Alarm (SPDT)
The PSHD meter supports user-configurable alarms for over-current, under-current, over-voltage, and
under-voltage. ViewPoint HD helps users set these values by allowing for values to be entered using
direct entry mode or specifying the limits as a percentage of nominal.
Alarm persistence settings are used to allow for temporary conditions, such as a motor starting, that are
beyond trigger limits. For example, in the case of meter upset from ESD events, short persistence settings
may lead to false alarm triggers. When any alarm condition has been satisfied throughout the persistence
interval, the PSHD trips the MASTER ALARM relay, which is an electromechanical relay on the PCB.
Once tripped, the relay can only be reset by clearing the alarm through Modbus register/ BACnet object
2451.
The Master Alarm relay can be hard wired to an interrupt or polling circuit in a host system allowing for a
more rapid response than the data polling frequency, if desired. The status of each alarm is determined
by reading status registers.
Refer to the register list, ViewPoint HD, or instructional videos for more information.
Note: The Master Alarm relay is intended for low voltage DC connections.
The user must protect the switch from over
-current conditions when closed.
12 Volt Auxiliary Power
The PSHD meter provides an auxiliary 12-volt output that is derived from an auxiliary winding on the
PSHD’s line-connected power supply. The 12-volt supply voltage is unregulated but protected by a self-
resetting fuse. The purpose of the supply is to power external radio equipment or provide supply voltage
for analog sensors, such as 4-20 mA current loop devices. If full-rated current is drawn from this terminal,
the minimum operating voltage of the L1-L2 power supply is 100 VAC.
