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

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 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 3 position switch
- With a Multi Control Panel
Please see section 5.5.1. 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)
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).
