Important: You must read these simplified instructions before proceeding. These instructions are to be used as a
reference only and are not intended to replace the details provided herein. You must read the Safety Warning, on
page 5, before proceeding.
Note: This drive contains bus capacitors, which must be reconditioned if the drive has been in storage for over 1
year. To recondition the bus capacitors, apply the AC line, with the drive in the Stop Mode, for a minimum of 30
minutes.
See Figure 1. Also see Section 4 - Important Application Information, on page 10.
WARNING! HIGH VOLTAGE – Disconnect main power before making connections to the drive.
Do not depend on the green Power On LED (ON), located on the drive's PC board, as shown in Figure
4, on page 9, or the Status LEDs and the 4-Digit Display, located on the front cover, to no longer be
illuminated as a guaranteed power off condition.
Note: It is recommended that both Feed-Through Bushings be used to connect the drive. If signal wiring (for
the Multi-Function Output Relay contacts or for a Remote Speed Potentiometer) is required, it is recommended
that the extra Feed-Through Bushing (supplied) be used to replace the center Hole Plug. Standard ½" fittings
(not supplied) can also be used in lieu of the Feed-Through Bushings.
