4.4.5 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 optional control panel) will require
subsequent configuration (see Section 5).
In the event of connecting MultiPlus units in parallel, the following requirements must be
met:
- A maximum of six units 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 directly from one unit to the other (and to the remote panel).
Connection/splitter boxes are not permitted.
- 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.
- Voltage sensing must be connected to the master (see Section 5.5.1.4).
- If more than three units are connected in parallel in one system, a dongle is required (see Section 5).
- Only one remote control means (panel or switch) can be connected to the system.
4.4.6 Three-phase operation (see appendix D)
The MultiPlus can also be used in 3-phase configuration. To this end, a connection
between the devices is made by means of standard RJ45 UTP cables (the same as for
parallel operation). The system (MultiPlus units plus an optional control panel) will require
subsequently configuration (see Section 5).
Pre-requisites: see Section 4.4.5.
