E54C3C Installation Guide
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.

NEC Article 100
If this product is used in a manner not specified by the manufacturer, the protection
provided by the product may be impaired. No responsibility is assumed by the
manufacturer for any consequences arising out of the use of this material.
DANGER
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.
NOTICE
• This product is not intended for life or safety applications.
• Do not install this product in hazardous or classified locations.
• The installer is responsible for conformance to all applicable codes.
• Mount this product inside a suitable fire 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.

Product Overview
The E54C3C energy meter works on a on a single-phase, three-phase, or three-phase + neutral network with
partial metering and reset functions. The meter requires 1 Amp or 5 Amp current transformers. Data values are
instantly accessible using either the local display or the communications network. The E54C3C is equipped with
Modbus communication via RS-485. It provides four-quadrant energy measurements with one configurable
digital input, one configurable digital output, and up to four tariffs.
Important: COM.Protection is a mode that prevents changes to any meter setting related to energy
measurement, such as wiring configuration, through Modbus communication. This mode is enabled by default.
To allow configuration over Modbus, first disable COM.Protection via the configuration menu on the display.
Refer to the Configuration section of this guide.
