UPS Mains Supply
(3 x 380/400/415V)
UPS Bypass Supply
(1 x 220/230/240V)
WIRING NOTES
1. Connect the supply neutral to the bypass neutral
terminal (Mains 2 (N)).
DO NOT connect the supply neutral to the input
neutral terminal (Mains 1 (N)) as there is a
possibility that the bypass current could return
through, and overload, the smaller cable of Mains
1.
2. Connect the three-phase mains input cable to
L1,L2,L3 and the bypass input cable to M2.
3. Connect the battery cables to the external battery
cabinet if used (see paragraph 3.8).
4. Remove the link between JP1 and JP2 if the
module is part of a parallel module system.
5. Connect the output terminals to the output
breaker/load distribution board. The load
distribution breakers should have a leakage
current protective function to suit to the UPS
voltage and current ratings.
