Parallel connection
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 an optional control panel) will require subsequent configuration, see the Configuration chapter.
In the event of connecting MultiPlus units in parallel, the following requirements must be met:
A maximum of six units can be connected in parallel.
Only identical devices may be connected in parallel.
The DC connection cables to the devices must be of equal length and cross-section.
If a positive and a negative DC distribution point is used, the cross-section of the connection between the batteries and the DC distribution point must at least equal the sum of the required cross-sections of the connections between the distribution point and the MultiPlus units.
Place the MultiPlus units close to each other, but allow at least 10 cm for ventilation purposes under, above and beside the units.
UTP cables must be connected with an RJ45-splitter from one unit to the other (and to the remote panel).
A battery-temperature sensor need only be connected to one unit in the system. If the temperature of several batteries is to be measured, you can also connect the sensors of other MultiPlus units in the system (with a maximum of one sensor per MultiPlus). Temperature compensation during battery charging responds to the sensor indicating the highest temperature.
Only one means of remote control (panel or switch) can be connected to the system.
