*1 Assuming the use of bare wiring (without rack or duct): 600 V class of vinyl-insulated IV wires for 60°C, 600 V class of
polyethylene-insulated HIV wires for 75°C, and 600 V class of polyethylene-insulated cross-link wires for 90°C.
Notes: 1) A box () in the above table replaces A, C, E, or U depending on shipping destination.
2) A box (■) in the above table replaces S (Basic type) or E (EMC filter built-in type) depending on the
enclosure.
3) Values in parentheses ( ) in the above table denote wire sizes for the European version.
If environmental requirements such as power supply voltage and ambient temperature differ
from those listed above, select wires suitable for your system by referring to Table 6.1 and
Appendices, App. F "Allowable Current of Insulated Wires."
