1. SAFETY INSTRUCTIONS General Please familiarize yourself with the safety features and instructions by first reading the documentation supplied with this product before using the equipment. This product has been designed and tested in accordance with international standards. The equipment must be used exclusively for the purpose for which it was designed.
Transport and Storage Ensure that the mains power and battery leads have been disconnected before storing or transporting the product. No liability can be accepted for any transport damage if the equipment is shipped in non- original packaging. Store the product in a dry environment; the storage temperature must be between -40°C and 70°C.
2. DESCRIPTION 2.1 General Multifunctional The Multi gets its name from the multiple functions it can perform. It is a powerful true sine wave inverter, a sophisticated battery charger that features adaptive charge technology and a high-speed AC transfer switch in a single enclosure. Beside these primary functions, however, the Multi has several advanced features that provide a range of new applications as outlined below.

Preventing damage due to excessive gassing: the BatterySafe mode If, in order to quickly charge a battery, a high charge current in combination with a high absorption voltage has been chosen, damage due to excessive gassing will be prevented by automatically limiting the rate of voltage increase once the gassing voltage has been reached.
3. OPERATION 3.1 On / Off / Charger-only Switch When switched to ‘on’, the product is fully functional. The inverter will come into operation and the LED ‘inverter on’ will light up. An AC voltage connected to the ‘AC in’ terminal will be switched through to the ‘AC out’ terminal, if within specifications.
3.3 LED Indications LED off LED flashes LED illuminated Inverter/Charger/ On / Off / Charger-only switch = On The inverter is switched on and supplies power to the load. On / Off / Charger-only switch = On The inverter is switched on and supplies power to the load. Pre-alarm: overload, or battery voltage low, or inverter temperature high.

Charger only On / Off / Charger-only switch = Charger only The AC input voltage is switched through and the charger operates in bulk or absorption mode. On / Off / Charger-only switch = Charger only The AC input is switched through and the charger operates in float or storage mode.
4. INSTALLATION This product should be installed by a qualified electrician. 4.1 Location The product must be installed in a dry and well-ventilated area, as close as possible to the batteries. There should be a clear space of at least 10cm around the appliance for cooling. a.

Internal DC Fuses 1600VA 1600VA 12V - 24V Automotive Bolt-Down Fuse MIDI or BF1 fuse 200A – 125A MIDI or BF1 fuse All servicing must be undertaken by qualified personnel. 4.3 Connection of the AC cabling This is a Safety Class I product (supplied with a protective grounding terminal). Uninterruptible protective grounding must be provided at the AC input and/or output terminals and/or chassis grounding point located externally on the product.
4.4 Optional Connections A number of optional connections are possible: Undo the four screws at the front of the enclosure and remove the front panel. 4.4.1 Second Battery The Multi has a connection (+) for charging a starter battery. For connection see appendix A. Trickle charge output is protected by automatic overcurrent &...

4.4.6 Three-phase operation (see appendix D) The MultiPlus can also be used in 3-phase wye (Y) configuration. To this end, a connection between the devices is made by means of standard RJ45 UTP cables (the same as for parallel operation). The system (MultiPlus units plus an optional control panel) will require subsequently configuration (see Section 5).

5.2 Explanation of settings Settings that are not self-explanatory are described briefly below. For further information, please refer to the help files in the software configuration programs (see Section 5.3). Inverter frequency Output frequency if no AC is present at the input. Adjustability: 50Hz;...

Ground relay (see appendix B) With this relay (H), the neutral conductor of the AC output is grounded to the chassis when the back-feed safety relay is open. This ensures the correct operation of earth leakage circuit breakers in the output. If a non-grounded output is required during inverter operation, this function must be turned off.
(which is quite rare!). Also turn on the dynamic current limiter simultaneously and reduce the maximum charging current to prevent overloading the generator if necessary. BoostFactor Change this setting only after consulting with Victron Energy or with an engineer trained by Victron Energy! Programmable relay By default, the programmable relay is set as an alarm relay, i.e.
5.3 Configuration by computer All settings can be changed by means of a computer. Some settings can be changed with DIP switches (see Section 5.4). For changing settings with the computer, the following is required: - VEConfigure3 software: can be downloaded free of charge at www.victronenergy.com. - A MK3-USB (VE.Bus to USB) interface, and a RJ45 UTP cable.

Proceed as follows for quick detection of common faults. DC loads must be disconnected from the batteries and the AC loads must be disconnected from the inverter before the inverter and/or battery charger is tested. Consult your Victron Energy dealer if the fault cannot be resolved. Problem Cause...
