3.6.3 Parallel Units Wiring
Note: Prior to wiring, first read 3.6.1 Precautions Prior to Wiring.
Single Input (Parallel Units)
When there is only one AC power source, parallel units’ wiring procedures are as follows.
1
Follow steps
1
~
5
in section 3.6.2 Single Input (Single Unit).
2
Connect the main AC source/ output/ external battery cabinet cables to the wiring terminal block and do not forget to ground the
parallel UPS systems (refer to Figures 3-1~3-12/ 3-19).
3
Use the provided parallel cable to connect the parallel ports on the parallel units. See Figure 6-1 for parallel port location.
4
Refer to 6. Communication Interfaces to set the parallel switch in the ON or OFF position.
5
Follow steps
7
~
8
in section 3.6.2 Single Input (Single Unit).
WARNING:
1. When UPS systems are paralleled, the length of each unit’s input cables/output cables must be equal. This
ensures that the parallel UPS systems can equally share the equipment loads in bypass mode.
2. Only UPS systems with the same capacity, voltage and frequency can be paralleled; otherwise, parallel
functions will fail.
3. Before start-up of parallel units, qualified service personnel should set ID (0, 1, 2 or 3) through the LCD.
Otherwise, UPS systems cannot be started. If the symbol ‘!’ appears after an ID number, it indicates there is a
conflict between ID numbers.
