    1. SAFETY INSTRUCTIONS In general Please read the documentation supplied with this product first, so that you are familiar with the safety signs en directions before using the product. This product is designed and tested in accordance with international standards. The equipment should be used for the designated application only.
  • Page 4 2. DESCRIPTION 2.1 In general The basis of the MultiPlus is an extremely powerful sine inverter, battery charger and automatic switch in a compact casing. The MultiPlus features the following additional, often unique characteristics: Automatic and uninterruptible switching In the event of a supply failure or when the generating set is switched off, the MultiPlus will switch over to inverter operation and take over the supply of the connected devices.

  • Page 10 4. Installation This product may only be installed by a qualified electrical engineer. 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.
  • Page 11 4.3 Connection of the AC cabling The MultiPlus is a safety class I product (supplied with a ground terminal for safety purposes). Its AC input and/or output terminals and/or grounding point on the outside of the product must be provided with an uninterruptible grounding point for safety purposes.
  • Page 12 4.4 Optional Connections A number of optional connections are possible: 4.4.1 Second Battery The MultiPlus has a connection for charging a starter battery. For connection see Appendix A. 4.4.2 Voltage Sense For compensating possible cable losses during charging, two sense wires can be connected with which the voltage directly on the battery or on the positive and negative distribution points can be measured.
  • Page 13 5. Configuration • Settings may only be changed by a qualified electrical engineer. • Read the instructions thoroughly before implementing changes. • During setting of the charger, the AC input must be removed. 5.1 Standard settings: ready for use On delivery, the MultiPlus is set to standard factory values. In general, these settings are suitable for single-unit operation. Warning: Possibly, the standard battery charging voltage is not suitable for your batteries! Refer to the manufacturer's documentation, or to your battery supplier!

BoostFactor Change this setting only after consulting with Victron Energy or with an engineer trained by Victron Energy! Not adjustable with DIP switches. Three programmable relays The MultiPlus is equipped with 3 programmable relays.
  • Page 16 5.3 Configuration by computer All settings can be changed by means of a computer or with a VE.Net panel (except for the multi-functional relay and the VirtualSwitch when using VE.Net). The most common settings can be changed by means of DIP switches (see Section 5.5). NOTE: This manual is intended for products with firmware xxxx400 or higher (with x any number) The firmware number can be found on the microprocessor, after removing the front panel.
  • Page 17 5.5 Configuration with DIP switches A number of settings can be changed using DIP switches (see appendix A, position M). A number of settings can be changed using DIP switches (see appendix A, position M). Note: When changing settings with DIP switches in a parallel or split-phase/3-phase system one should be aware that not all settings are relevant on all Multis.
