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 specied by the manufacturer, the protection provided by the device may
be impaired.
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.
• Any covers that may be displaced during the installation must be reinstalled
before powering the unit.
• Use a properly rated voltage sensing device to confirm power is off.
DO NOT DEPEND ON THIS PRODUCT FOR VOLTAGE INDICATION
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 the installation, and has received safety
training to recognize and avoid the hazards involved. NEC2009 Article 100
No responsibility is assumed byVeris Industries for any consequences arising out of the
use of this material.
DANGER
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.
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.

The E50H2A and E50H5A DIN rail power meters provide a solution for measuring energy data with a single device.
Inputs include control power, CT, and 3-phase voltage. Both models support BACnet MS/TP protocol. The E50H2A
has one pulse contact input and a phase loss alarm output. The E50H5A has data logging capability and two pulse
contact inputs. The LCD screen on the faceplate allows instant output viewing. These meters include built-in CT
integrators and CT power supplies. The E50H2A and E50H5A work only with Veris U018 series rope style CTs.
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
meters are not sensitive to CT orientation, reducing installation errors.
