Installation and User Manual
2.6.4 AC Output
The connections to be made are the three phases, and ground cables from the load source to the UPS. The
output cables are terminated at the Output Terminal Block (TB2) for 40-80kVA, and the output busbars for 100-
150kVA.
Load cables must be run separately from all other cables (power supply or computer-system interconnection
cables). They should not pass near interference-emitting equipment or sensitive loads.
2.6.5 Battery
The connections to be made are the positive, negative, and ground cables from the battery cabinet to the UPS.
These are terminated at the appropriate connections in the UPS cabinet (see Figures 2-3 and 2-4). Additionally,
control wires and temperature sensors in the battery cabinet must be terminated. Refer to the battery cabinet
installation drawings for more details.
