1.4 Designated use

The multifunction electrical energy meter is designed to record, display and transmit

electrical measured values in low-voltage systems with a maximum nominal voltage of

EngyVolt RV12 Safety instructions

500 V L-L (289 V L/N), power connection via low-voltage current transformer x/5A at a

nominal frequency of 45 to 66 Hz. It is suitable for use in single-phase power systems, and

in three-phase power systems with three or four wires.

Among other values, the electrical energy meter measures the voltage, frequency, current,

power, power factor, total harmonic distortion (THD) as well as active energy and reactive

energy.

• The manufacturer accepts no liability for damages resulting from incorrect use or use

other than that designated. It is not permitted to convert or modify the device in any

way.

• The device is designed for mounting on a top-hat rail according to DIN 43880 and must

only be operated in an installed state.

1.5 Technical improvement

The manufacturer reserves the right to modify technical data without prior notice. Please

contact your sales center for information on modifications or updates to the Operating

Instructions.

1.6 Return

The device must be packed in protective packaging if it is being returned for repair, for

example. The original packaging offers the best protection. Repairs may only be performed

by your supplier's service organization.

Installation EngyVolt RV12

3 Installation

3.1 Incoming acceptance, transport, storage

Compliance with the permitted storage and transportation conditions is mandatory.

Precise specifications are provided in the "Technical data" section (→  28).

3.1.1 Incoming acceptance

On receipt of the goods, check the following points:

• Is the packaging or the content damaged?

• Is the delivery complete? Compare the scope of delivery against the information on your

order form.

3.1.2 Transport and storage

Please note the following:

Pack the device so that is protected against impact for storage and transport. The original

packaging provides optimum protection.

3.2 Installation conditions

The device can be mounted on a standard top-hat rail.

Measuring devices must be mounted in a dry location at stable ambient temperatures that

do not exceed or drop below the range of –10 to 55 °C (14 to 131 °F). There should be

minimum tension from vibrations. If possible, the measuring device should be mounted in

such a way that the contrast of the display is not affected by direct sunlight or strong

lighting. The LCD display is optimized for vertical reading. If the display is read

horizontally, lighting conditions can affect the readability of the display.

Wiring EngyVolt RV12

4 Wiring

!WARNING

Danger! Electric voltage!

‣The entire electrical connection must be performed when the device is de-energized.

‣Establish the protective ground connection before making any other connections.

NOTICE

Cable heat load

‣Use suitable cables for temperatures that are 5 °C (9 °F) above the ambient

temperature.

Incorrect supply voltage can damage the device or cause malfunctions

‣Before commissioning the device, make sure that the supply voltage matches the

voltage specifications on the nameplate.

Incorrect wiring can damage the device

‣Observe the terminal designations on the device.

Electrical overloading can damage the device

‣Provide overcurrent protection elements for the power cables.

‣Provide a suitable switch or power-circuit breaker for emergency shutdown in building

installations. This switch must be provided close to the device (within easy reach) and

marked as a circuit breaker.

4.1 Supply voltage

The supply voltage is designed for the range from 100 to 400 V AC and 120 to 350 V DC.

Preferably, the supply voltage should be provided from a source other than the measured

voltage. The measured voltage can be used if it is within the tolerance limits of the supply

voltage.

4.2 Electrical connection

To ensure maximum accuracy, we recommend that the current signal connecting cables

pass through additional ferrite cores (e.g. of type 742 701 110 from Würth Elektronik) at

least six times.
