Remark:
1. For the Series UPS, input neural line should be directly connected to input “N” termi-
nal of UPS wire connection terminal bay without AC input idle-run;
2. When single-phase current exceeds 100A, switches of protective atmosphere should be
equipped with arc control devices;
3. Battery positive/negative wire size: indicates UPS and battery box wire size; red wire
signifies the positive polarity and black wire the negative,while blue wire the neutral.
4. Proper positioning in line with above specifications should be done prior to installa
-
tion.
11) Sequence of phase A, B and C should be properly connected otherwise UPS will dis-
play wrong phase sequence fault and start-up will fail.
12) Connect one end of communication line to terminal RS232 of UPS while the other end
to terminal RS232 of PC. PC supervision over UPS can be realized after successful instal-
lation of WinPower supervising software on PC.
1) Follow installation instructions for general installation requirements.
2)Ventilation spacing between machine flanks should be a minimum of 10cm and a mini-
mum of 50cm (considering the space for replacing fans) for the back for machine.
3) Input wiring for each set of UPS should follow the requirements for that of single unit.
Each UPS input should be connected to the same input patch board.
4) Each UPS output wire should be connected to the output patch board, from which wires
are distributed for load as illustrated in following figure.
Remark 1: common battery pack is applicable in parallel machine mode;
Remark 2: each battery pack should be of the same model from the same manufacturer;
Remark 3: requirement of output wiring length:
When the lead from the output terminal of each set of UPS to the output patch board is
less than 20m, wire difference should be less than 20%;
When the lead from the output terminal of each set of UPS to the output patch board is
longer than 20m, wire difference should be less than 10%.
