ATTENTION: The drive contains high voltage capacitors which take 

time to discharge after removal of mains supply. Before working on 

drive, ensure isolation of mains supply from line inputs [R, S, T (L1, 

L2, L3)]. Wait three minutes for capacitors to discharge to safe voltage 

levels. Failure to do so may result in personal injury or death.

Darkened display LEDs is not an indication that capacitors have 

discharged to safe voltage levels.

!

ATTENTION: Only qualified personnel familiar with adjustable 

frequency AC drives and associated machinery should plan or 

implement the installation, start-up and subsequent maintenance of the 

system. Failure to comply may result in personal injury and/or 

equipment damage.

!

ATTENTION: This drive contains ESD (Electrostatic Discharge) 

sensitive parts and assemblies. Static control precautions are required 

when installing, testing, servicing or repairing this assembly. 

Component damage may result if ESD control procedures are not 

followed. If you are not familiar with static control procedures, 

reference A-B publication 8000-4.5.2, “Guarding Against Electrostatic 

Damage” or any other applicable ESD protection handbook.

!

ATTENTION: An incorrectly applied or installed drive can result in 

component damage or a reduction in product life. Wiring or application 

errors, such as, undersizing the motor, incorrect or inadequate AC 

supply, or excessive ambient temperatures may result in malfunction of 

the system.

!

ATTENTION: The bus regulator function is extremely useful for 

preventing nuisance overvoltage faults resulting from aggressive 

decelerations, overhauling loads, and eccentric loads. However, it can 

also cause either of the following two conditions to occur.

1. Fast positive changes in input voltage or imbalanced input voltages 

can cause uncommanded positive speed changes;

2. Actual deceleration times can be longer than commanded 

deceleration times

However, a “Stall Fault” is generated if the drive remains in this state 

for 1 minute. If this condition is unacceptable, the bus regulator must be 

disabled (see parameter A117). In addition, installing a properly sized 

dynamic brake resistor will provide equal or better performance in most 

cases.

ATTENTION: To avoid an electric shock hazard, ensure isolation of 

mains supply from line inputs [R, S, T (L1, L2, L3)] and wait three 

minutes for capacitors to discharge before removing the external cover. 

Once the cover is removed, verify that the voltage on the bus capacitors 

has discharged before performing any work on the drive. Measure the 

DC bus voltage at the DC– and DC+ terminals on the Power Terminal 

Block (refer to page 1-13 for Power Terminal descriptions). The voltage 

must be zero

Mounting Considerations

Debris Protection

A plastic top panel is included with the drive. Install the panel to prevent 

debris from falling through the vents of the drive housing during 

installation. Remove the panel for IP20, NEMA/UL Type Open 

applications.

Storage

• Store within an ambient temperature range of -40° to +85°C.

• Store within a relative humidity range of 0% to 95%, 

non-condensing.

• Do not expose to a corrosive atmosphere.

AC Supply Source Considerations

General Grounding Requirements

The drive Safety Ground - (PE) must be connected to system 

ground. Ground impedance must conform to the requirements of 

national and local industrial safety regulations and/or electrical codes. 

The integrity of all ground connections should be periodically checked.

Figure 1.3 Typical Grounding

Ground Fault Monitoring

If a system ground fault monitor (RCD) is to be used, only Type B 

(adjustable) devices should be used to avoid nuisance tripping.

Safety Ground - (PE)

This is the safety ground for the drive that is required by code. One of
