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 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.

These limits are designed to provide reasonable protection against harmful interference when this 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. Operation of this equipment in a residential area may cause harmful interference in which case the user will be required to correct the interference at his own expense. Modifications to this product without the express authorization of Veris Industries nullify this statement.

Documentation must be consulted where this symbol is used on this product.

INSTALLATION
Disconnect power prior to installation.

Any covers that may be displaced during the installation must be reinstalled before powering the unit.

Mount the meter in an appropriate electrical enclosure near equipment to be monitored.
Do not install on the load side of a Variable Frequency Drive (VFD).
The meter can be mounted in two ways: on standard 35 mm DIN rail or screw- mounted to the back of the enclosure.
A. DIN Rail Mounting 1. Attach mounting clips to the underside of the housing by sliding them into the slots from the inside. The stopping pegs must face the housing, and the outside edge of the clip must be flush with the outside edge of the housing. 2. Snap the clips onto the DIN rail. See diagram of the underside of the meter. 3. To prevent horizontal shifting across the DIN rail, use two end stop clips.

B. Screw Mounting 1. Attach the mounting clips to the underside of the housing by sliding them the slots from the outside. The stopping must face the housing, and the screw must be exposed on the outside of the housing. 2. Use three #8 screws (not supplied) to the meter to the back of the enclosure. diagram of the underside of the meter.

SUPPORTED SYSTEM TYPES
The meter has a number of different possible system wiring configurations (see Wiring Diagrams, page 9-10). To configure the meter, set the System Type via the User Interface. The System Type tells the meter which of its current and voltage inputs are valid, which are to be ignored, and if neutral is connected. Setting the correct System Type prevents unwanted energy accumulation on unused inputs, selects the formula to calculate the Theoretical Maximum System Power, and determines which phase loss algorithm is to be used. The phase loss algorithm is configured as a percent of the Line- to-Line System Voltage (except when in System Type 1L + 1n) and also calculates the expected Line to Neutral voltages for system types that have Neutral (2L + 1N and 3L + 1n).
Values that are not valid in a particular System Type will display as “—-” on the User Interface.

Fuse Recommendations:

Keep the fuses close to the power source (obey local and national code requirements). For selecting fuses and circuit breakers, use the following criteria: · Current interrupt capacity should be selected based on the installation category and fault
current capability. · Over-current protection should be selected with a time delay. · The voltage rating should be sufficient for the input voltage applied. · Provide overcurrent protection and disconnecting means to protect the wiring. For DC
installations, the installer must provide external circuit protection (suggested: 0.5 A time delay fuses).
· The earth connection is required for electromagnetic compatibility (EMC) and is not a protective earth ground.

Notes when connecting to non-HOBO® devices:
· The T-VER-E50B2 has solid-state outputs rated for 30VAC/DC nom. · VARh and Wh are normally open; Ah is normally closed. · Maximum load current is 100mA at 25°C. Derate 0.56mA per °C above 25°C (e.g.
86mA@50°C). · The over-current protective device must be rated for the short circuit current at the
connection point. · Pulse outputs are only intended to be connected to non- hazardous voltage circuits
(SELV or Class 2). Do not connect to hazardous voltages.
