The MultiPlus is provided with a ground relay (relay H, see appendix B) that automatically connects the Neutral output to the
chassis if no external AC supply is available. If an external AC supply is provided, the ground relay H will open before the input
safety relay closes. This ensures the correct operation of an earth leakage circuit breaker that is connected to the output.
• In a fixed installation, uninterruptable grounding can be secured by means of the grounding wire of the AC input. Otherwise the
casing must be grounded.
• In a mobile installation, interrupting the shore connection will simultaneously disconnect the grounding connection. In that case,
the casing must be connected to the chassis (of the vehicle) or to the hull or grounding plate (of the boat).
• In case of a boat, direct connection to the shore ground is not recommended because of potential galvanic corrosion. The
solution to this is using an isolation transformer.
The mains input & output terminal connector can be found on the bottom of the MultiPlus, see appendix A. The shore or mains
cable must be connected to the connector with a three-wire cable. Use a three-wire cable with a flexible core and a cross section
of at least 6 mm². Recommended torque: 1,6 Nm
Procedure (see appendix A) Do not invert neutral and phase when connecting the AC.
The inverter does incorporate a mains frequency isolating transformer. This precludes the possibility of DC current at any AC port.
Therefore type A RCD’s can be used.
•AC-in
The AC input cable can be connected to the terminal block ‘AC–in’.
From right to left: “N” (neutral), “PE” (earth) and “L” (phase)
The AC input must be protected by a fuse or magnetic circuit breaker rated at 32A, and cable cross-section must be
sized accordingly. If the input AC supply is rated at a lower value, the fuse or magnetic circuit breaker should be down sized
accordingly.
•AC-out
The AC output cable can be connected directly to the terminal block ‘AC-out’.
From left to right: “N” (neutral), “PE” (earth) and “L” (phase)
With its PowerAssist feature the MultiPlus can add up to 2kVA (that is 2000 / 230 = 9A) to the output during periods of peak
power requirement. Together with a maximum input current of 32A this means that the output can supply up to 32 + 9 = 41 A.
An earth leakage circuit breaker and a fuse or circuit breaker rated to support the expected load must be included in series with
the output, and cable cross-section must be sized accordingly.
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 & overload protection (trip current 1A Imax= 5,5A)
4.4.2. Temperature Sensor
The temperature sensor supplied with the product may be used for temperature-compensated charging. The sensor is insulated
and must be mounted on the battery minus pole. Default output voltages for Float and Absorption are at 25°C. In adjust mode
temperature compensation is disabled.
4.4.3. Remote Control
The product can be remotely controlled in two ways:
• With an external on/off switch (Remove Link “Remote Switch connector H”)
• With a Multi Control Panel
Please see section 5.4 for appropriate DIP switch settings.
4.4.4. Programmable relay
The MultiPlus is equipped with a multi-functional relay that by default is programmed as an alarm relay. The relay can be
programmed for all kinds of other applications however, for example to start a generator (VEConfigure software needed).
4.4.5. Parallel Connection (see appendix C)
The MultiPlus can be connected in parallel with several identical devices. To this end, a connection is established between the
devices by means of standard RJ45 UTP cables. The system (one or more MultiPlus units plus optional control panel) will require
subsequent configuration (see Section 5).
