Introduction
There are two meters in the MD-xxHD Series: the MD-12HD and the MD-48HD. These meters monitor
the voltage, current, power, energy, and many other electrical parameters on single and three-phase
electrical systems. A MD-xxHD meter uses direct connections to each phase of the voltage and current
transformers to monitor each phase of the current. Information on energy use, demand, power factor, line
frequency, and more are derived from these voltage and current inputs.
The MD-xxHD meter is not meant to be a standalone energy recorder; rather it is connected as a slave
device to a data logger, Remote Terminal Unit (RTU), or Building Management host network. The
MD-xxHD meter communication interfaces include Ethernet (LAN) or RS-485 serial. BACnet MS/TP and
Modbus RTU are the two communication protocols that operate over an RS-485 serial network and
BACnet IP and Modbus TCP are supported over Ethernet. A USB port is also provided as the preferred
connection for on-site configuration and can be run concurrently with an RTU.
Unpacking the Unit

Meter Safety
Building Service Safety Requirements
(Load Center, etc.)
Equipment intended for use with field-installed current transformers that could be
installed in panel boards or switchgears shall observe the following:
Always open or disconnect circuit from power-distribution system (or service) of building
before installing or servicing current transformers.
A circuit breaker used as a disconnect must meet the requirements of IEC 60947-1 and
IEC 60947-3 (Clause 6.11.4.2)
Current transformers may not be installed in equipment where they exceed 75 percent
of the wiring space of any cross-sectional area within the equipment.
Current transformers may not be installed in an area where they block ventilation
openings.
Current transformers may not be installed in an area of breaker arc venting.
Not suitable for Class 2 wiring method nor intended for connection to Class 2
equipment.
Secure current transformer and route conductors so that they do not directly contact live
terminals or bus.
CTs shall be listed to UL2808
Meter Installation Safety Requirements
MD-xxHDmeters must be installed in accordance with local electrical codes.
Use copper conductors only.
Connection to the mains terminals shall be made with 14 AWG minimum wire gauge.
External secondary inputs and outputs should be connected to devices meeting the
requirements of IEC 60950.
The following additional requirements apply for recognized board versions of the MD-
xxHD meter:
1. For use only with Listed Energy-monitoring Current Transformers.
2. Associated leads of the current transformers shall be maintained within the same overall
enclosure.
3. Unless the current transformers and its leads have been evaluated for REINFORCED
INSULATION, the leads must be segregated or insulated from different circuits.
4. The current transformers are intended for installation within the same enclosure as the
equipment. These may not be installed within switchgears and panel boards or similar.

Planning For Field Installation
Project Manager Aspects
Meter installation often includes coordination between individuals or groups of people with different
responsibilities. Spend a few minutes considering who will be executing each portion of the installation
and what tools are needed at each stage. Things to consider include determining how to communicate
with the meter, setting address configuration, installing ViewPoint HD, access to PIN numbers, etc. The
more tasks completed before installation the fewer tasks will be needed in the field, where most mistakes
happen. The following section gives an overview of typical process activities followed by details in the
next section.
Configuration and Data Viewing Options
The MD-xxHD meter has three methods for configuration and data viewing. The most powerful interface
is a Microsoft Windows application (ViewPoint HD) that runs on PCs or Tablets. ViewPoint HD is
encouraged for complex installations and is required for configuring advanced functions like alarms. The
second interface is the MD-xxHD Web App and is intended for smart phones or tablets that can connect
over USB, or Ethernet. The third interface (LCD) is an optional component and is intended for intermittent
end-user observation and is restricted in capability. The RTU can also be used for configuration if
communication settings are already established.The feature set of each interface is summarized next.

Meter Configuration - Details
This section is written to support setting up the MD-xxHD in an office environment and
configuring the power meter for a pre-determined configuration. In many cases, the
setup is standardized for an organization or project. In other cases, the setup can be
documented and emailed to an installer. The setup can also be performed on-site and
reflect “as-built” configurations.
The MD-xxHD meter cannot be configured using ViewPoint HD over a serial port. RS-485 serial
network configurations must be pre-configured or use Modbus/BACnet hosts.
This section describes the use of the ViewPoint HD Windows Application. If this interface
cannot be used, see the section on using the simplified MD-xxHD Web App interface. The web
browser can be accessed from the USB port to support Mac users.
Install the ViewPoint HD Software
Insert the ViewPoint HD thumb drive into the computer or download from:
https://www.dentinstruments.com/siemens
Locate the ViewPoint HD Installer and open this folder.
Typical Installation
Double-click the “RunMe to Install ViewPoint HD.bat”batch file to install ViewPoint and its support files
in Windows default location. This option works for most users.

17 Siemens Industry, Inc.
Custom Installation
For users who want to specify the location of the ViewPoint HD software and support files, double-click
the folder Install Files and run setup.exe. This will prompt the user for additional details.
Installation Trouble Shooting
Successful installation of ViewPoint HD may be prevented by settings specific to your PC for the following
reasons:
1) Anti-virus protection software may interfere with the installation of ViewPoint HD. If the installation
does not complete for this reason, try temporarily disabling the virus protection software on your
PC and re-attempt the installation.
2) Administrative Access. In some cases, user privilege settings may disallow the installation of new
applications. This may require logging in as an administrator.

Siemens Industry, inc. 18
Connection and Configuration Options Using ViewPoint HD
When the ViewPoint HD application is launched, it will prompt the user to select one of four connectivity
options.
•Connect over USB cable
•Connect over Ethernet to a Predetermined IP address
•Scan Network
•Create Setup file only (no meter connected)
NOTE: The USB connection method is recommended for new users who have physical access to the meter
and a USB A to B cable (supplied). Check out this option first!
ViewPoint HD Connection Options
USB Connection (Power and Communications)
Connect the MD-xxHD meter to a USB port of your computer to provide both power and communications.
a. If equipped, the LCD display is the most visable indication of a running meter.
b. For meters without a display, a green flashing LED on the circuit board indicates that the MD-
xxHD meter has booted and is running.
c. The MD-xxHD meter draws 450 mA from the USB port which may overload “out of spec” USB
hosts. If the meter fails to power, or flickers when powering over USB, an alternate configuration
for power must be used.

19 Siemens Industry, Inc.
Preferred Connection via USB A to B Cable
d. Launch the ViewPoint HD application and press the CONNECT OVER USB button on the pop-up
window.
The meter should now be communicating. The ViewPoint HD application offers visual guides and context
help to facilitate meter configuration. Read the ViewPoint HD overview section (below) or watch the
tutorial videos for additional information on configuring the meter. By default, MD-xxHD meters are
configured for DNS Ethernet addressing. A very common configuration sequence is using USB to
configure a meter for Ethernet communications at a static IP address and then switching from USB over
to Ethernet to locate it. This is facilitated in ViewPoint HD by pressing the Refresh Connectivity icon
located in the upper right hand corner.
