Introduction
The E50H2-T2 DIN rail power meter provides a solution for measuring energy data with a single
device Inputs include control power, CT, and 3-phase voltage The E50H2-T2 supports BACnet TP
protocol The E50H2-T2 has one pulse contact input and a phase loss alarm output The LCD
screen on the faceplate allows instant output viewing
The meter is housed in a plastic enclosure suitable for installation on T35 DIN rail according to
EN50022 It can be mounted with any orientation over the entire ambient temperature range,
either on a DIN rail or in a panel The E50H2-T2 meters are not sensitive to CT orientation,
reducing installation errors

Warnings, Cautions, and Notices
Safety advisories appear throughout this manual as required Your personal safety and the
proper operation of this machine depend upon the strict observance of these precautions
The three types of advisories are defined as follows:
WARNING
Indicates a potentially hazardous situation which, if not avoided, could result in
death or serious injury.
CAU TION
Indicates a potentially hazardous situation which, if not avoided, could result in
minor or moderate injury. It could also be used to alert against unsafe practices.
NOTICE
Indicates a situation that could result in equipment or property-damage only
accidents.
Important Environmenta Concerns
Scientific research has shown that certain man-made chemicals can affect the earth’s naturally
occurring stratospheric ozone layer when released to the atmosphere In particular, several of the
identified chemicals that may affect the ozone layer are refrigerants that contain Chlorine,
Fluorine and Carbon (CFCs) and those containing Hydrogen, Chlorine, Fluorine and Carbon
(HCFCs) Not all refrigerants containing these compounds have the same potential impact to the
environment Trane advocates the responsible handling of all refrigerants-including industry
replacements for CFCs and HCFCs such as saturated or unsaturated HFCs and HCFCs
Important Responsib e Refrigerant Practices
Trane believes that responsible refrigerant practices are important to the environment, our
customers, and the air conditioning industry All technicians who handle refrigerants must be
certified according to local rules For the USA, the Federal Clean Air Act (Section 608) sets forth
the requirements for handling, reclaiming, recovering and recycling of certain refrigerants and
the equipment that is used in these service procedures In addition, some states or municipalities
may have additional requirements that must also be adhered to for responsible management of
refrigerants Know the applicable laws and follow them

Insta ation
Read the following guidelines before starting installation
• Disconnect power prior to installation
• Reinstall any covers displaced during installation before re-powering unit
• Mount the meter in an appropriate electrical enclosure near equipment to be monitored
• Do not install the load side of a variable frequency drive (VFD)
Mount the meter using one of the following two methods:
1 DIN Rail Mount
a Attach mounting clips to the underside of housing by sliding them into the slots from the
inside
NNoottee:: The stopping pegs must face the housing and the outside edge of the clip must be
flush with the outside edge of the housing.
b Snap the clips onto the DIN rail

Supported Systems
The E50H2-T2 meter has a number of different possible system wiring configurations (Refer to
the table below and next section, Wiring Diagrams) To configure the meter, set the System Type
via the User Interface or by writing the Present_Value of AV2 with the system type value listed in
the following table The system type tells the meter which of its current and voltage inputs are
valid, which are to be ignored, and if neutral is connected Setting the correct system type
prevents unwanted energy accumulation on unused inputs, selects the formula to calculate the
Theoretical Maximum System Power, and determines which phase loss algorithm is to be used
The phase loss algorithm is configured as a percent of the Line-to-Line System Voltage (except
when in System Type 10) In addition, it calculates the expected Line-to-Neutral voltages for
system types that have Neutral (12 & 40) Values that are not valid in a particular System Type
display as ———— on the User Interface or as QQNNAANN in the BACnet objects
NNoottee:: To avoid distortion, use parallel wires for control power and voltage inputs.

#1: Direct Connect Control Power, Line-to-Line #2: Line-to-Neutral from 90 Vac to
347 Vac (UL) or 300 Vac (CE)
#3: DC Control power from 125 VDC
to 300 VDC (UL and CE max)
Line-to-Line from 90 Vac to 600 Vac (UL). In UL
installations the lines may be floating (such as
a delta). If any lines are tied to an earth (such as
a corner grounded delta), refer to the
Line-to-Neutral installation limits. In CE
compliant installations, the lines must be
neutral (earth) referenced at less than 300 VacL-N
#4: Control power transformer may be wired
L-N or L-L. Output to meet meter
input requirements
Fuse Recommendations
Keep the fuses close to the power source For selecting fuses and circuit breakers, use the
following criteria:
• Select current interrupt capacity based on the installation category and fault current
capability
• Select over-current protection with a time delay
• Use a voltage rating sufficient for the input voltage applied
• Provide over-current protection and disconnecting means to protect the wiring
NNoottee:: . For AC installations, use Trane A 04 or equivalent. For DC installations, provide
external circuit protection. Suggested: 0.5A, time delay fuses rated for DC operation at
or above the supply voltage
• Use the earth connection (G) for electromagnetic compatibility (EMC), not a protective earth
ground
