1�- VERIFICATION UPON RECEPTION

Check the following points when you receive the device:

a) The device meets the specications described in your order.

b) The device has not suffered any damage during transport.

c) Perform an external visual inspection of the device prior to switching it on.

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

- An installation guide,

- 2 Retainers used to attach the device,

- 5 connectors.

If any problem is noticed upon reception, immediately contact the transport

company and/or LIFASA's after-sales service.

2�- PRODUCT DESCRIPTION

The MCA PLUS II device 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 6 versions of the device, depending on the type of current input:

MCA PLUS II - ITF, indirect current measurement with /5A or /1A transformers.

MCA PLUS II - ITF-IN, indirect current measurement with /5A or /1A transformers and

an input to measure the neutral current.

MCA PLUS II - MC, indirect current measurement with efcient transformers of the

MC1 and MC3 series.

MCA PLUS II - MC-IN, indirect current measurement with efcient transformers of the

MC1 and MC3 series and an input to measure the neutral current.

MCA PLUS II - mV indirect current measurement with /0.333V transformers.

MCA PLUS II - FLEX current measurement through Rogowski sensors.

The device features:

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

- 3 indicator LEDs: CPU, ALARM and KEY.

- LCD display, displays all parameters,

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 vari-

ous warnings indicated in this instruction manual.

The MCA PLUS II 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 measure-

ments.

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

MCA PLUS II

3.2.- INSTALLATION

The device 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 haz-

ardous 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.

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

3.3.- MCA PLUS II - FLEX : ROGOWSKI SENSORS

The MCA PLUS II - FLEX model measures currents using exible sensors, based on the Ro-

gowski coil principle.

The exibility of the sensor allows it to measure an alternating current irrespective of the posi-

tion of the conductor.

LIFASA has 2 Rogowski sensor models that can be used with the MCA PLUS II - FLEX: FLEX-

MAG and FLEX-BAY.

Table 3 shows the connection of the sensors and Table 2 the maximum position error.

Note: For more information, consult the corresponding sensor guide.
