NOTE 1 Select conduit taking into consideration the DC input wire sizes listed in Table 3‐4 on page 3-14, Table 3‐5 on page 3-15, Table 3‐6 on page 3-16
and Table 3‐7 on page 3-17 the DC terminations listed in Table 3‐11 on page 3-20, type of battery installation, and requirements from NEC Table 4,
Electrical Metallic Tubing (EMT).
NOTE 2 Because of the future upgradability to a fully rated 825 kVA UPS with the addition of the FI-UPM, these conduit sizes are specified for an
825kVA UPS.
NOTE 3 Bypass conduit data is not applicable to IOM configurations.
