KB Electronics KBVF-23P - Manual (Page 30)

Application Note – To avoid erratic operation, do not bundle the AC line and motor wires with each
other or with wires from signal following, start/stop contacts, or any other signal wires. Also, do not
bundle 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. Wire the drive in
accordance with the National Electrical Code requirements and other local codes that may apply.
Be sure to properly fuse each AC line conductor that is not at ground potential. Do not fuse neutral
or grounded conductors. A separate AC line switch or contactor must be wired as a disconnect so
that each ungrounded conductor is opened. For fuse or circuit breaker selection, see Table 1, on
page 14. Also see section 10, on page 35.
9.1 AC Line Connection – Wire the AC line input as described below. The terminals are located
on the upper PC board. See Figure 16, on page 31.
GFCI Operation – Do not connect this drive to an AC power source controlled by a
Ground Fault Circuit Interrupter. Special software is available for GFCI operation —
contact our Sales Department.
