In the event of connecting Quattro units in parallel, the following requirements
must be met:
• A maximum of six units connected in parallel.
• Only identical devices with the same power ratings may be connected in
parallel.
• Battery capacity should be sufficient.
• 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 Quattro units.
• Place the Quattro 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, the
sensors of the other Quattro units in the system can be used (with a
maximum of one sensor per Quattro). 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 (panel or switch) can be connected to the
system.
4.6.6 Three-phase configuration (see appendix C)
Quattro’s 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 (Quattro’s plus an
optional control panel) will require subsequent configuration (see Section 5).
Pre-requisites: see Section 4.6.6.
4.6.7 Two phase (split phase) configuration (see appendix C)
Quattro’s can also be used in split 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 (Quattro’s plus an
optional control panel) will require subsequent configuration (see Section 5).
Pre-requisites: see Section 4.6.6.
