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
Carefully read the instructions before changes are made.
Batteries should be placed in a dry and well-ventilated area during charging.
5.1 Standard settings: ready for use
On delivery, the Multi is set to standard factory values. In general, these settings are
suitable for single-unit operation.
Warning: Possibly, the standard battery charging voltage is not suitable for your
batteries! Refer to the manufacturer's documentation or to your battery supplier!
