Any manipulation or use of the equipment out of the conditions
specified by the manufacturer may put in risk the user safety
. Before
any maintenance operation the equipment must be disconnected from power
supply. In case of miss operation or protection fault the equipment must be
disconnected from supply and remain out of service ensuring against any
accidental reconnection.
1.- Regulator Connection
For proper operation it’s necessary to install a current transformer, CT
(normally In / 5 A), which primary must be sized according to the
maximum expected load current in the installation.
The regulator supply (C-D terminals) must be taken between two
phases and the CT should be located in the third phase. See technical
characteristics for cable sizes and required protections.
Must use an switch or automatic switch for supply the regulator
The current transformer , CT,
must be located so that it
measures the whole load current
plus the correction capacitors
