1 Introduction
The Energy Meter (P/N 250-5000) provides a solution 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.
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 over-current 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.
