(3)Connect the external signal terminal block as desired. Refer to section 2.4 and Figure 2.15 for functional description. 2mm2, or less, shielded conductor is recommended.

NOTES: 1. Confirm that all UPS internal contactors (breakers) "CB1", "CB2", and "CB3" are open before energizing UPS.

2.UPS power terminals are supplied with stud type fittings. It is recommended that compression lugs be used to fasten all input/output power cables.

6.Procedure for Cable Connections for Parallel System

(1)Confirm the number of units to be connected in parallel. Identify the input/output power terminal blocks and control wire connections for parallel systems as shown in the appropriate Figures 3.4a~c.

(2)Connect the external control wire and power wire.
