This manual is a CVM-C4 installation guide. For further information, please download the full manual from the CIRCUTOR web site: www.circutor.com
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 device’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-C4 is a device that measures, calculates and displays the main
electrical parameters in single-phase and three-phase mains.
The device has RS-485 communications, relay outputs, impulse outputs and
digital inputs.
Current measurement is indirectly carried out by /5A or /1A transformers.
INSTALLATION
The device should be installed inside an electric panel or enclosure, and panel-mounted.
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
To install it, take the following steps:
- Make a cut in the panel, according to the dimensions in Figure 1.
- From outside, insert the device into the panel cut-out (Figure 2).
- Fully insert the device and fasten it securely by using the spring (Figure 3)
CONNECTION
The device should be connected to a power circuit protected by a fuse with a
maximum rated current of 0.25 A.
If the voltage to be measured is higher than the rated input voltage, a
voltage transformer must be connected to the device.
If more than one device is connected to the current transformer, they must be
connected in series.
Before disconnecting the current measurement connection cables, be sure to
disconnect the transformer’s primary cables and bridge the secondary.
The device can operate in three-wire, three-phase mode or four-wire, three-
phase mode, the user selecting the corresponding connection mode according to
the installation. An incorrect type of connection or an error in phase
sequence may cause measurement errors.
