4.4.6 Three-phase operation (800VA and 1200VA models only, 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 and a splitter (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.
Note: the MultiPlus is not suitable for 3-phase delta (Δ) configuration.
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!
