Trane E50 Series Installation, Operation And Maintenance Manual page 2

Introduction
The E50 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 E50 supports multiple output
options, including solid state relay contacts and Modbus. 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. The E50 can be mounted with any orientation over the entire
ambient temperature range, either on a DIN rail or in a panel. The meter is not sensitive to CT
orientation to reduce 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:
Important Environmental 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 Responsible 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.
