1.6 JUMPER SETTINGS – All jumpers have been factory set for most applications, as shown in Figure 4,
on page 12. Some applications require setting of the jumpers in order to set the drive for a specific
application. Jumper J2 must be set to match the horsepower of the motor being used. See Section 7,
on pages 16 – 18.
1.7 60 Hz and 50 Hz MOTOR OPERATION – The drive is factory set for 60 Hz motor operation (Jumper J5
set to the “60Hz” position). For 50 Hz motor operation, set Jumper J5 to the “50Hz” position. See Section
7.4, on pages 17 and 18.
1.8 PILOT LIGHT – After applying power to the drive and setting the On/Off AC Line Switch to the “ON”
position, the panel mounted Pilot Light will illuminate.
1.9 DIAGNOSTIC LEDs – After applying power to the drive and setting the On/Off AC Line Switch to the “ON”
position, observe the PC board mounted LEDs for proper drive operation. See Section 10, on pages 20 & 21.
1.10 TRIMPOT SETTINGS – All trimpots have been factory set for most applications, as shown in Figure 4,
on page 12. Some applications require adjustment of the trimpots in order to setup the drive for a specific
requirement. See Section 11, on pages 21 – 23.

This product should be installed and serviced by a qualified technician, electrician, or electrical
maintenance person familiar with its operation and the hazards involved. Proper installation,
which includes wiring, fusing or other current protection, and grounding can reduce the chance of electrical
shocks, and/or fires, in this product or products used with this product, such as electric motors, switches,
coils, solenoids, and/or relays. Do not use this drive in an explosion-proof application. Eye protection must
be worn and insulated adjustment tools must be used when working with drive under power. This product is
constructed of materials (plastics, metals, carbon, silicon, etc.) which may be a potential hazard. Proper
shielding, grounding, and filtering of this product can reduce the emission of radio frequency interference
(RFI) which may adversely affect sensitive electronic equipment. It is the responsibility of the equipment
manufacturer and individual installer to supply this Safety Warning to the ultimate end user of this product.
(SW 1/2006)
The drive contains electronic Start/Stop circuits which can be used to start and stop the drive. However,
these circuits are never to be used as safety disconnects since they are not fail-safe. Use only the AC line
for this purpose.
Be sure to follow all instructions carefully. Fire and/or electrocution can result due to improper use of this
product.
