11.1 80/100/125 kVA Terminal Blocks and Power Cables

Note: Always consult your site specific, local, state, and NEC electrical codes for wiring, cabling, and circuit protection device requirements.

The terminal blocks for the 80/100/125 kVA UPS are shown in Figure 11.3.

Recommended external cable sizes for both 75 °C and 90 °C copper wire for a single battery string are listed in Table 11.1–11.2. For two or more battery strings consult with Toshiba Technical Support. Ensure that your installation adheres to local and NEC electrical codes.

Use only copper wires for external cables.
