1Introduction
The Energy Meter (P/N 250-5000) provides a so-
lution for measuring energy data with a single device.
Inputs include Control Power, CT, and 3-phase voltage. The Energy Meter 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
EN50022. The Energy Meter 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.
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.
WARNING! 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 ser-
viced 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.
Provide a disconnect device to disconnect the Energy 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 disconnecting 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.
