3�- DEVICE INSTALLATION

3.1.- PRIOR RECOMMENDATIONS

In order to use the device safely, it is critical that individuals who handle it follow the safety measures set out 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-E3-MINI device 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 device. It is dangerous to handle the device

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 device 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.

If an anomaly or malfunction is detected in the device, do not use it to take any measurements.

Inspect the work area before taking any measurements. Do not take measurements in danger-

ous areas or where there is a risk of explosion.

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

Instruction Manual

3.2.- INSTALLATION

The device must be installed on an electric panel or enclosure, attached to a DIN rail (IEC

60715).

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

The device 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 device from the power supply network. 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.

To guarantee the insulation of the device and its category, it is necessary to earth the S2 terminals of the transformers.

The temperature rating of insulation of wires connected to the device will be at minimum 62ºC.

3.3.- PANEL MOUNTING ACCESSORY (72 x 72 mm)

Note: The 72 x 72 mm panel mounting accessory is an accessory that is sold separately.

CIRCUTOR has a panel mounting accessory of the CVM-E3-MINI equipment so that it can be installed on 72 x 72 mm panels.

Figure 1: CVM-E3-MINI with panel mounting accessory�

Figure 2 shows the installation of the panel mounting accessory to the CVM-E3-MINI.

Disconnect all power supplies and measuring equipment from the device before carrying out the installation of the panel mounting accessory.

Use keys and to browse the different screens.

The inst symbol on the left of the screen indicates that the values being displayed are of the instantaneous type.
