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.
• 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 remote can be connected to the system.
4.4.6. Three-phase operation (see appendix D)
The MultiPlus can also be used in 3-phase wye (Y) 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.
