    Exercise extreme care when handling cabinets to avoid equipment damage or injury to personnel. The Vertiv™ Liebert® EXM MBC weight ranges from 225-332 lb. (102-151 kg). Locate center of gravity symbols and determine unit weight before handling each cabinet. Test lift and balance the cabinets before transporting.

  • Page 12 (see Table 3.11 on page 35). Ensure correct phase rotation. 7. Connect the control wiring from the Liebert® EXM MBC terminal block TB1 to the Vertiv™ Liebert® EXM UPS Bypass Module (X9, J23, and J26). Tighten the connections to the proper torque (see Table 3.11 on page 35).
  • Page 13 In most installations, the load equipment is connected to a distribution network of individually protected busbars fed by the Vertiv™ Liebert® EXM MBC output rather than being connected directly to the Liebert® EXM MBC itself. Where this is the case, the Liebert® EXM MBC output cables can be rated to suit the individual distribution network demands rather than being fully load rated.
