4.3. AC connection
This product 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.
The Multi is provided with a ground relay, see the
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 the 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 AC input and output terminal connectors can be found at the bottom of the Multi, see the
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 1.5 mm²
The inverter does incorporate a mains frequency isolating transformer. This precludes the possibility of DC current at any AC port.
Therefore, type A RCDs can be used.
AC connection procedure
Proceed as follows to connect the AC cables:
1.
The AC output cable can be connected directly to the male connector (the connector pulls out).
2.
The terminal points are indicated clearly. From left to right: neutral (N), earth (PE), and phase (L1).
3.
The AC input cable can be connected directly to the female connector (the connector pulls out).
4.
The terminal points are indicated clearly. From left to right: neutral (N), earth (PE), and phase (L1).
5.
Push the "input" connector into the AC-in connector.
6.
Push the "output" connector into the AC-out connector.
4.4. Optional connections
A number of optional connections are possible:
4.4.1. Second battery
The Multi has a connection (+) for charging a starter battery. For connection see the
trickle charge output is protected by automatic overcurrent and overload protection (trip current=1A Imax= 5.5 A).
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 3-position switch
• With a Multi Control Panel
Please see the
Configuration by DIP switches [16]
4.4.4. Programmable relay
The Multi 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, for example, to start a generator (VEConfigure software or VictronConenct app needed).
