IMPORTANT!
The device must be disconnected from its power supply sources (power supply and measurement) before undertaking any installation, repair or handling operations on the unit’s connections.
Contact the after-sales service if you suspect that there is an operational fault in the device.
The device has been designed for easy replacement in case of malfunction.
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.
DESCRIPTION
The CVM-E3-MINI-WiEth device measures calculate and display 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.
CVM-E3-MINI-ITF-WiEth, indirect current measurement with /5A or /1A transformers.
INSTALLATION
The device must be installed on an electric panel or enclosure, attached to a DIN rail (IEC 60715).
IMPORTANT!
Take into account that when the device is connected, the terminals may be hazardous to the touch, and opening the covers or removing elements may provide access to parts that are dangerous to the touch. 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 fitted 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 1mm 2.
The secondary line of the current transformer will have a minimum cross-section of 2.5 mm 2.
It’s mandatory to connect the current transformer to the ground, see Connections.
The temperature rating of insulation of wires connected to the devices will be at a minimum of 62ºC
