HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH
• Follow safe electrical work practices. See NFPA 70E in the USA, or applicable local codes.
• This equipment must only be installed and serviced by qualified electrical personnel.
• Read, understand and follow the instructions before installing this product.
• Turn off all power supplying equipment before working on or inside the equipment.
• Product may use multiple voltage/power sources. Disconnect all sources of power
before servicing.
• Use a properly rated voltage sensing device to confirm power is off.
DO NOT DEPEND ON THIS PRODUCT FOR VOLTAGE INDICATION.
• Current transformer secondaries must be shorted or connected to a burden at all times.
• Products rated only for basic insulation must be installed on insulated conductors.
• Replace all doors, covers and protective devices before powering the equipment.
Failure to follow these instructions will result in death or serious injury.
A qualied person is one who has skills and knowledge related to the construction and
operation of this electrical equipment and installations, and has received safety
training to recognize and avoid the hazards involved. NEC2014 Article 100

• The installer is responsible for conformance to all applicable codes.
• Mount this product inside a suitable re and electrical enclosure.
FCC PART 15 INFORMATION
NOTE: This equipment has been tested by the manufacturer and found to
comply with the limits for a class B digital device, pursuant to part 15 of
the FCC Rules. These limits are designed to provide reasonable protection
against harmful interference when the equipment is operated in a
residential environment. This equipment generates, uses, and can radiate
radio frequency energy and, if not installed and used in accordance with
the instruction manual, may cause harmful interference to radio
communications. This device complies with part 15 of the FCC Rules.
Operation is subject to the following two conditions:
(1) This device may not cause harmful interference, and
(2) this device must accept any interference received, including
interference that may cause undesired operation.
Modifications to this product without the express authorization of the
manufacturer nullify this statement.
WARNING
LOSS OF CONTROL
∙ Assure that the system will reach a safe state during and after a control path failure.
∙ Separate or redundant control paths must be provided for critical control functions.
∙ Test the eect of transmission delays or failures of communication links.1
∙ Each implementation of equipment using communication links must be individually
and thoroughly tested for proper operation before placing it in service.
Failure to follow these instructions may cause injury, death or equipment damage.
1For additional information about anticipated transmission delays or failures of the link, refer to
NEMA ICS 1.1 (latest edition). Safety Guidelins for the Application, Installation, and Maintenance
of Solid-State Control or its equivalent in your specic country, language, and/or location.
Control system design must consider the potential failure modes of control paths and, for
certain critical control functions, provide a means to acheive a safe state during and after a
path failure. Examples of critical control functions are emergency stop and over-travel stop.
Product Overview
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, Modbus (with or without data logging), and pulse. 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.
