1. VERIFICATIONS UPON RECEPTION

The following must be checked upon reception of the device:

a) The device has been supplied according to the specifications in your order.

b) The device has not been damaged during transport.

c) Perform an external visual inspection of the device before connecting it.

d) Check that it has been supplied with the following:

RECmax-CVM 2-pole:

- An installation guide.

- 1 MC1-75/0.25A measuring transformer

- 1 WGC-20SC earth leakage transformer

RECmax-CVM 4-pole:

- An installation guide.

- 1 MC3-75/0.25A measuring transformer

Immediately contact the carrier and/or CIRCUTOR's after-sales service if you

detect any problem in the device upon reception.

2. DESCRIPTION OF THE PRODUCT

RECmax-CVM is a protection device, with cut-off capacity, which features overcurrent protection, ul-

tra-immunised earth leakage protection and a power analyzer.

The device is programmable and features a display. It measures the leakage current (earth leakage

protection) and orders the disconnection and reclosing of the circuit breaker (protection) through a

mechanically-operated motor.

There are 2 models available:

RECmax-CVM 2-pole, for single-phase installations.

RECmax-CVM 4-pole, for three-phase installations.

The device features:

- Inputs for the measurement of current and earth leakage current.

- 3 keys that can be used to browse the various screens and program the device.

- 2 Indicator LEDs.

- LCD Display, to view the parameters.

- 2 inputs for remote control and locking.

RECmax-CVM

Instruction Manual

- 2 alarm outputs.

- 1 output to indicate the status of the main switch.

- 1 digital output.

- RS-485 communications.

3. INSTALLING THE DEVICE

3.1.- PRELIMINARY RECOMMENDATIONS

The operators using and handling the device must follow the safety measures estab-

lished in the country where the device will be used to guarantee its safe operation,

using personal protective equipment if needed.

The RECmax-CVM device must be installed by authorised and qualified staff.

Disconnect the device from the mains and disconnect the measuring devices before handling, chang-

ing the connections of or replacing the device. Handling the device while it is connected is hazardous

to people nearby.

The cables must be in perfect working order to prevent accidents or injuries to people and/or damage

to the facilities/installations.

Limit the operation of the device to measuring the specified current or voltage values.

The manufacturer of the device shall not be held responsible for any damage resulting from the user

or installation company failing to observe the warnings and/or recommendations indicated in this

manual nor for any damage resulting from the use of non-original products or accessories or those

from other brands.

Inspect the device before using it. Make sure that there are no cracks and that the housing is intact.

Do not use the device to take measurements if you detect an anomaly or malfunction.

Check the environment in which the device is installed before taking a measurement. Do not use the

device to take measurements in dangerous, explosive, wet or damp environments.

Disconnect the device from the mains and from the power supply (both the device and

its measuring system) before performing any maintenance work, repairs or handling

any of the connections of the device.

Contact the after-sales service if you detect that the device is not working properly.

RECmax-CVM

Instruction Manual

3.2.- INSTALLATION

While the device is connected, the terminals, opening the cover or removing elements

can expose parts that are hazardous to the touch. The device must not be used until

the installation process is complete.

The RECmax-CVM must be installed inside an electric panel or enclosure and mounted on a DIN rail

46277 (EN 50022).

The device has connection indicator LEDs, indicating the presence of voltage. Even if these LEDs are

not on, the user must still verify that the device is disconnected from all power supplies.

3.2.1.- MEASUREMENT OF THE EARTH LEAKAGE CURRENT I

The earth leakage current must be measured using the WGC earth leakage transformer included with

the device.

The WGC transformer, supplied with a cable and 2-pole connector,must be connected to terminals 1

and 2 of the device (see Table 3)

It is recommended to place the earth leakage transformer at the bottom of the circuit breaker (Figure

6and Figure 7).

The external earth leakage transformer is necessary for the device to operate cor-

rectly. Even if its installation only appears linked to the correct working of the earth

leakage protection, failing to install it will affect other functions of the device, such

as the reclosing and display of parameters on the RECmax-CVM display.

An incorrect or faulty connection of the earth leakage transformer means loss of

the earth leakage protection and possible risk of electric shock.

In case of a faulty connection of the earth leakage transformer or if this transformer is not compati-

ble with the RECmax-CVM, the screen shown in Figure 1 will appear.
