CIRCUTOR's after-sales service. 2�- PRODUCT DESCRIPTION The CVM-E3-MINI 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.
The CVM-E3-MINI device must be installed by authorised and qualified staff. The power supply plug must be disconnected and measuring systems switched off before handling, altering the connections or replacing the device.
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.

COMMUNICATIONS” 7.1.- CONNECTIONS The RS -485 cable must be wired with twisted pair cable with mesh shield (minimum 3 wires), with a maximum distance between the CVM-E3-MINI and the master device of 1200 metres. A maximum of 32 CVM-E3-MINI devices can be connected to this bus.
CVM-E3-MINI 7.2.- MODBUS PROTOCOL In the Modbus protocol, the CVM-E3-MINI device uses the RTU (Remote Terminal Unit) mode. The Modbus functions implemented in the device are as follows: Function 0x03 and 0x04. Reading integer registers. Function 0x05. Writing a relay.
Map 2, uses the addresses of the CVM-C10 device (adding 0x1000 to all addresses). Except for 3 parameters, the CVM-C10 and the CVM-E3-MINI use the same parameters. Map 2 should be used if a Modbus map is going to be implemented from scratch. However, if the map is already being used in another device, use Map 1 for CVM-MINI and Map 2 for CVM-C10.
