Optional Connections; Temperature Sensor - Victron energy MultiPlus 12 500 20 Manuel

The mains input & output terminal connector can be found on the bottom of the Multi, 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
1.5mm².
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).
The AC input cable can be connected directly to the female-connector. (the connector pulls
out!)
The terminal points are indicated clearly. From left to right: 'L1' (phase), earth, and 'N'
(neutral).
Push the 'input' connector into the AC-in connector.
Push the 'output' connector into the AC-out connector.

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. Trickel charge output is protected by automatic overcurrent & overload protection (trip
current 1 A 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 section 5.4.1. for appropriate DIP switch settings.
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 however, for example to
start a generator (VEConfigure software needed).
4.4.5 Parallel Connection (see appendix C)
