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.

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.
Procedure Proceed as follows to connect the battery cables: Use an insulated box spanner in order to avoid shorting the battery. Avoid shorting the battery cables. Connect battery cables to the Multi and battery, see appendix A. Reverse polarity connection will cause damage to the product. (Safety fuse inside the Multi can be damaged).
Procedure (see appendix A) Proceed as follows to connect the AC cables: The AC output cable can be connected directly to the male-connector. (the connector pulls out!) The terminal points are indicated clearly. From left to right: ‘N’ (neutral), earth, and ‘L1’ (phase).

In the event of connecting MultiPlus units in parallel, the following requirements must be met: - A maximum of six units connected in parallel. - Only identical devices may be connected in parallel. - The DC connection cables to the devices must be of equal length and cross-section. - If a positive and a negative DC distribution point is used, the cross-section of the connection between the batteries and the DC distribution point must at least equal the sum of the required cross-sections of the connections between the distribution point and the MultiPlus units.

5. CONFIGURATION Settings may only be changed by a qualified engineer Carefully read the instructions before changes are made. Batteries should be placed in a dry and well-ventilated area during charging. 5.1 Standard settings: ready for use On delivery, the Multi is set to standard factory values. In general, these settings are suitable for single-unit operation.

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.

5.4 Configuration with DIP switches Some settings can be changed with DIP switches. Procedure: a) Turn the Multi on, preferably without load and without AC voltage on the input. The Multi will then operate in inverter mode. b) Set the DIP switches as required. c) Store the settings by moving DIP switch 6 to ‘on’...

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...
