See Table 4-1 for terminal block wire and tightening torque
specifications.
WARNING! READ ALL SAFETY WARNINGS BEFORE USING THE
Application Note: To insure proper operation, position and
separate the AC line and motor connections, signal connections,
signal following circuitry, or start/stop contacts. Also, do not
combine (or in close proximity) motor wires from multiple drives
in the same conduit. Use shielded cables on all signal wiring over
12" (30 cm). The shield should be earth grounded on the drive
side only. Connect the drive in accordance with the National
Electrical Code requirements and other local codes that may
apply.
Be sure to properly fuse each conductor that is not at ground
potential. Do not fuse neutral or grounded conductors. A separate
AC line switch or contactor must be connected as a disconnect,
so that each ungrounded conductor is opened. For fuse or circuit
breaker rating, see Table 1-7. Also see Section 4.1.
