8 ELECTRICAL CONNECTIONS
The drive is designed with contactor-type feed-throughs to facilitate wring of the AC Line input,
Motor, and Ground connections, as shown in Figures 7 – 13, on pages 22 – 24. See Table 5, on
page 22.
The removable cover allows access to the terminal blocks and jumpers for wiring and setting up
the drive for Remote Operation in lieu of the Keypad (Local Operation).
Note: Wire the control in accordance with the National Electrical Code requirements and other
local codes that may apply to the application.
WARNING! HIGH VOLTAGE! Read Safety Warnings, on page 9, before using the
drive. Disconnect the main power before making connections to the drive. To avoid
electric shock, be sure to properly ground the drive.
Application Notes:
1. To avoid erratic operation, do not bundle AC Line input and motor wires with each other. 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.
2. 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 used as a
disconnect so that each ungrounded conductor is opened. For fuse or circuit breaker selection,
see Table 3, on page 15. Also see Section 8.2, on page 24.
3. If operation with a Ground-Fault Circuit-Interrupter (GFCI) is required, see Function 0.04, on
page 55.
