1.4 GROUND CONNECTION: Connect the ground wire (earth) to Terminal Block TB1 (Terminal "GND"), as
shown in Figure 1, on page 4.
1.5 MOTOR CONNECTION: Connect the motor to Terminal Block TB1 (Terminals "U", "V", "W"), as shown in
Figure 1, on page 4. Be sure the motor is properly grounded. Motor cable length should not exceed 100ft
(30 m) – special reactors may be required – consult our Sales Department. See Section 6.3, on page 13.
1.6 60 Hz AND 50 Hz MOTR OPERATION: The drive is factory set for 60 Hz motors (Function No. 0.00 set to
"0000"). For 50 Hz motors, set Function No. 0.00 to "0001", as shown in Figure 12, on page 16. For other
motor frequencies, set Function No. 0.00 to "0002".
1.7 JUMPER J1 SETTING: The drive is factory set for 208/230 Volt AC line input (Jumper J1 not installed).
For 115 Volt AC line input, install Jumper J1 (supplied). See Section 7, on page 14.
1.8 MOTOR OVERLOAD PROTECTION: Function No. 0.01 must be set to the motor nameplate current for
proper operation of the I 2 t Motor Overload Protection. See Figure 13, on page 17.
2 SAFETY WARNING
Definition of Safety Warning Symbols
Electrical Hazard Warning Symbol: Failure to observe this warning could result in electrical shock or
electrocution.
Operational Hazard Warning Symbol: Failure to observe this warning could result in serious injury or
death.
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 electrical connections, 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 read and follow all instructions carefully. Fire and/or electrocution can result due to improper
use of this product.
This product complies with all CE directives pertinent at the time of manufacture. Contact our Sales
Department for Declaration of Conformity. Installation of a CE approved RFI filter is required. See RFI Filters &
Chokes Selection Guide D-321 (Part No. A42027) for the selection of filters to meet the Industrial or Residential
Standard. Additional shielded cable and/or AC line cables may be required along with a signal isolator (IODA
Input/Output Multi-Function Board (Part No. 9668)).
