L11-N1、B-N1: the terminal for Bypass Input to provide the power source when
●
the UPS is working under bypass mode.
L12-N1、R-S-T-N1: the terminal for Utility Input to provide the power source
●
when the UPS is working under Utility mode.
G1: the terminal for UPS Input Ground.
●
L21、L23、N21、L22、N22: the terminals for UPS Output.
●
G2: the terminal for UPS Output Ground.

Remarks:
1. The maximum current for each terminal is 30Arms
10Kva.
2. If the UPS is DIM(Dual Input) type whose Utility and Bypass Sources are the
same, L11 and L12 would have to be shorted for 1-phase input model, and
short B and R for 3-phase input model.
3. If the UPS is SIM(Single Input) type, only AC source can be supplied to UPS
from L12-N1 terminal for 1-phase input model and R-S-T-N1 terminal for 3-
phase input model.
4. When the Isolation transformer is NOT installed into the tower type UPS, the
UPS output terminals will be L22-N22..
5. When the Isolation transformer is installed into the tower type UPS:
