Instruction Manual

1�- VERIFICATION UPON RECEPTION

Check the following points when you receive the unit:

a) The unit meets the specications described in your order. b) The unit has not suffered any damage during transport. c) Perform an external visual inspection of the unit prior to switching it on. d) Check that it has been delivered with the following:

- An installation guide,

- 2 Retainers for subsequent attachment of the unit

If any problem is noticed upon reception, immediately contact the transport company and/or CIRCUTOR's after-sales service.

2�- PRODUCT DESCRIPTION

CVM-C5

The CVM-C5 unit measures, calculates and displays the main electrical parameters of the following networks: single-phase, two-phase, with and without neutral, balanced three-phase, with ARON measurements or unbalanced. The measurement will be taken in RMS with the three AC voltage inputs and three current inputs.

There are 2 versions of the team based on the current input:

 CVM-C5-IC, indirect mesure corrent with transformers /5A and /1A.  CVM-C5-MC, indirect measure current with efcient transformers series MC1 and

MC3.

The unit features:

- 3 keys that allow you to browse between the various screens and program the unit.

- LCD Display to display all the parameters,

- 1 digital input to select the tariff.

- 1 programmable digital output to act as a pulse or alarm output.

3�- UNIT INSTALLATION

3.1.- PRIOR RECOMMENDATIONS

In order to use the unit safely, it is critical that individuals who handle it follow the safety measures described in the standards of the country where it is being used, use the necessary personal protective equipment, and pay attention to the various warnings indicated in this instruction manual.

The CVM-C5 unit must be installed by authorised and qualied staff.

The power supply plug must be disconnected and measuring systems switched off before handling, altering the connections or replacing the unit. It is dangerous to handle the unit while it is powered.

Also, it is critical to keep the cables in perfect condition in order to avoid accidents, personal injury and damage to installations.

The manufacturer of the unit is not responsible for any damage resulting from failure by the user or installer to heed the warnings and/or recommendations set out in this manual, nor for damage resulting from the use of non-original products or accessories or those made by other manufacturers.

In the event an anomaly or malfunction is detected in the unit, refrain from using it to take any measurements.

Inspect the work area before taking any measurements. Do not take measurements in dangerous areas or where there is a risk of explosion.

Disconnect the unit from the power supply (unit and measuring system power supply) before maintaining, repairing or handling the unit's connections. Please contact the after-sales service if you suspect that there is an operational fault in the unit.

3.2.- INSTALLATION

The unit will be installed on a panel (92

+0.8

x 92

+0.8

mm panel drill hole, in compliance with DIN

43700). All connections are located inside the electric panel.

Terminals, opening covers or removing elements can expose parts that are hazardous to the touch while the unit is powered. Do not use the unit until it is fully installed.

The unit must be connected to a power circuit that is protected with gl (IEC 269) or M type fuses with a rating of 0.5 to 2 A. It must be tted with a circuit breaker or equivalent device, in order to be able to disconnect the unit from the power supply network.

Instruction Manual

CVM-C5

The power and voltage measuring circuit must be connected with cables that have a minimum cross-section of 1mm2.

The secondary line of the current transformer will have a minimum cross-section of 2.5

mm2.
