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.
5. CONFIGURATION
Settings may only be changed by a qualified engineer
