For use in a Pollution Degree 2 or better environment only. A Pollution Degree 2 environment must
control conductive pollution and the possibility of condensation or high humidity. Consider the
enclosure, the correct use of ventilation, thermal properties of the equipment, and the relationship with
the environment. Installation category: CAT II or CAT III. Provide a disconnect device to disconnect the
meter from the supply source. Place this device in close proximity to the equipment and within easy
reach of the operator, and mark it as the disconnecting device. The disconnecting device shall meet the
relevant requirements of IEC 60947-1 and IEC 60947-3 and shall be suitable for the application. In the US
and Canada, disconnecting fuse holders can be used. Provide overcurrent protection and disconecting
device for supply conductors with approved current limiting devices suitable for protecting the wiring.
If the equipment is used in a manner not specified by the manufacturer, the protection provided by the
device may be impaired.

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 effect 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.
1
For additional information about anticipated transmission delays or failures of the link, refer to
NEMA ICS 1.1 (latest edition).
Safety Guidelines for the Application, Installation, and Maintenance
of Solid-State Control
or its equivalent in your specific 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 E50C1 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 E50C1 supports multiple output options, including solid state relay
contacts, Modbus, 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 EN 50022. The E50C1
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, reducing installation errors.
