After all the electrical connections of UPS have been made and while all the circuit breakers and switchtes
of the device are turned OFF (at “0” position);
1. Check the polarities of battery connections:
K1 : + V (Nominal v192V or +204V or +216V,
Float charge v216V or +229,5V or +243V)
K2-K2 : 0 V (common terminal for ‘’+’’ and ‘’-‘’ battery groups)
K3 : - V (Nominal voltage -192V or -204V or -216V,
Float charge voltage -216V or -229,5V or -243V)
2. Check 3-phase AC input and neutral connections (care should be taken for the phase order).
