Note: Disconnect main power when installing or changing the Plug-In

Horsepower Resistor®.

III. WIRING INSTRUCTIONS

Warning! Read Safety Warning, on page 5 before using this control.

Disconnect the AC line before wiring.

Note: To avoid erratic operation, do not bundle AC line and motor wires with wires

from signal following, Start/Stop Switch, Enable, or any other signal wires. Use

shielded cables on all signal wiring over 12” (30cm). Shield should be earth ground-

ed on the control side only. Wire the control in accordance with the National

Electrical Code requirements and other codes that may apply to your area. See

Figure 4 on page 13.

Be sure to properly fuse each conductor that is not at ground potential. Do not fuse

neutral or grounded conductors. See Section VIII, on page 18. A separate AC line

switch or contactor must be wired as a disconnect so that each ungrounded con-

ductor is opened. See Application Note, Section VII, on page 18.
