1. Safety Instructions

Victron VM-3P5A Energy Meter Manual 1. Safety Instructions General Please read the safety instructions below before installing and using the VM-3P5A energy meter to avoid risks of fire, electric shocks, personal injuries or equipment damage. This product is designed and tested in accordance with international standards. The equipment should be used for its designated application only and in accordance with the specified operating parameters. Installation Installation, maintenance, service and adjustments must be made by qualified personnel only. To reduce the risk of electric shock, do not perform any service other than that specified in the operating instructions unless you are qualified.

For electrical work, follow the local national wiring standards, regulations and these installation instructions. Connection to the mains supply must be in accordance with the national regulations for electrical installations. Never install near fire sources, explosive materials, combustibles or other flammable sources. Never use it at places where gas or other chemical explosions could occur. Turn off mains power before installing or performing operations on it. Do not put fingers or insert objects or sharp metallic objects into the terminals. Install it in a dry environment. Do not apply strong force on the equipment to prevent crashes and deterioration.

It is not allowed to use the current clamps on bare wires. Make sure the ground connection is properly done to prevent equipment damage. Operation, service and maintenance Do not use the device if it shows any signs of damage or does not function properly. Do not use the VM-3P5A if it is broken, defective, cracked, damaged, or malfunctioning. The VM-3P5A contains no serviceable parts. Regular maintenance of the VM-3P5A is not required. Avoid moisture, oil/soot/vapours, and keep the device clean. Clean using a dry cloth on the front side of the VM-3P5A. Page 1 Safety Instructions

2.1. Features

Victron VM-3P5A Energy Meter Manual 2. Introduction The VM-3P5A energy meter is a standard device to measure the power and energy of single-, split- and three-phase applications and calculates each phase's power values and broadcasts this over VE.Can or Ethernet with a high rate. It supports industry-standard 5 A current transformers (not included) and is self-powered from all phases (N-L1-L2-L3). Built-in Ethernet and VE.Can ports enable direct connection to a GX device. The energy meter works out of the box (the firmware may need to be updated; details can be found in the Firmware Updates [11] chapter) as a grid meter for systems with a MultiPlus, Quattro, Multi RS and Multi HS.

Configuration (via VictronConnect) is only required for changing the role and manual IP configuration rather than the default DHCP. Its data is displayed on a GX device such as the Cerbo GX or Ekrano GX , as well as in VictronConnect and our VRM Portal . 2.1. Features Supports industry-standard 5 A current transformers (not included) Modbus/UDP communication over Ethernet Support for 1-phase, split-phase and 3-phase configuration Configurable total energy registration: vector, arithmetic, or absolute Reports:

line-to-neutral voltage line-to-line voltage power factor (according to IEEE convention) phase sequence (for 3-phase configuration) phase rotation warning (for 3-phase configuration) protective earth voltages neutral and line currents The VM-3P5A can be configured for various roles in a GX device, such as the Cerbo GX or the Ekrano GX . Depending on the application, it can be used:

Status LED can be set as a pulse counter for quick, at-a-glance diagnostics as a grid meter, providing control input for an Energy Storage System (ESS) to measure the output of a PV inverter to measure the output of an AC genset as an AC meter to measure a dedicated AC load circuit to track an EV charger to track a heat pump It offers two options for connection to a GX device: 1. A wired Ethernet connection to the local network via the built-in Ethernet port, allowing the GX device to communicate with it. 2. A wired VE.Can connection via the onboard VE.Can port, directly linking it to the GX device. Page 2 Introduction

3.1. Installing and wiring external current transformers (CTs)

Victron VM-3P5A Energy Meter Manual 3. Installation 3.1. Installing and wiring external current transformers (CTs) The VM-3P5A requires external current transformers (CTs) for current measurement. CTs are not included and must be sourced separately. Victron Energy does not supply CTs for the VM-3P5A. CT requirements Use CTs with a 5 A secondary output The CT primary current setting in the VM-3P5A must match the CT rating. For example, a CT marked 100/5 A must be configured as 100 A primary current. See Configuration & Monitoring [8] for details on how to configure the primary current. Connect the CT secondary terminals as follows: Wiring the CTs Ensure the polarity is correct on all phases.

Reversed polarity will result in incorrect power and energy readings. CT orientation If the CT is marked with a direction arrow or polarity indicator, install it with the marking pointing from the AC source towards the loads. For CTs with S1/S2 polarity markings, S1 should face the AC source side and S2 the load side. Important notes Use one CT per phase and connect each CT to the corresponding input terminal (CT-1, CT-2, CT-3). Ensure the phase voltage inputs and CTs correspond to the same phase. Do not install CTs on bare conductors. Follow the CT manufacturer’s installation instructions to avoid damaging the transformer. CT extension cables may increase measurement noise.

To minimise induced noise, use twisted pair wiring. Page 4 Installation • S1 / + → CT-[1..3] left terminal of the connector (top view) • S2 / – → CT-[1..3] right terminal of the connector (top view) S1S2 S1S2 S1S2
