General Precautions
ATTENTION: To avoid an electric shock hazard, ver ify that the v oltage on the bus
capacitors have 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 Chapter 1 Power Terminal descriptions). The voltage must be zero.
Darkened LEDs or a darkened displa y are 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.
ATTENTION: An incorrectly applied or installed drive can result in component
damage or a reduction in product life. W iring or applicat ion errors, such as, under sizing 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 over voltage fau lts resulting from aggressive dec elerations, 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 “Sta ll Fault” is gener ated if the drive remains in this stat e for 1 minute. If this condition is unacceptable, the bus regulator must be disabled. In addition, inst alling a properly sized dynam ic brake resistor will provide equal or better performance in most cases.

AC supply source considerations
Ungrounded Distribution Syste ms
ATTENTION: ILVFE drives contain protective MOVs that are referenc ed to ground.
These devices must be dis connected if the drive is installed on an ungrou nded or resistive grounded distribution system.
Disconnecting MOVs
To prevent drive damage, the MO Vs c onn ec ted t o gr o und s ha ll be dis connected if the drive is instal le d on an ungrounded distr ibution system where th e line-to-ground voltages on any phase could excee d 125% of the nom inal line-to-line voltage. To disconn ect these devices, remove the jumper shown in the Figures 1.1 and 1.2 below
1. Turn the screw counterclockwise to loosen.
2. Pull the jumper completely out of the drive chassis.
3. Tighten the screw to keep it in place.
Figure 1.1 Jumper Location (Frame A shown)
Figure 1.2 Phase to Ground MOV Removal
Important: Tighten screw after jumper removal.

Input Power Conditioning
The drive is suitable for direct connection to input power within the rated voltage of the drive (see Appendix A).
Listed in Table 1.C are certain input power conditions which may cause component damage or reduction in product life.
If any of the conditions exist as described in Table 1.C, install one of the devices listed under the heading Corrective Action on the line side of the drive.
Important: Only one device per branch circuit is required. It should be mounted closest to the branch and sized to handle the total current of the branch circuit.
Table 1.C Input Power Conditions
Input power condition Corrective action
Low line impedance (less than 1% line reactance)
• Install line reactor.
• Install isolation transformer.
Greater than 120 kVA supply transformer
Line has power factor correction capacitors
Line has frequent power interruptions
Line has intermittent noise spikes in excess of 6000V (lightning)
Phase to ground voltage exceeds 125% of normal line voltage
• Remove MOV jumper to ground.
• Install isolation transformer with grounded secondary if necessary.

General grounding requirem e nt s
The drive safety ground (PE) must be connected to system ground. Ground impedance mus t conf orm to the r equirements of national and local indus t rial s af et y regulat io ns
and/or electrical codes. The integrity of all ground connections should be periodically checked
.
Figure 1.3 Typical grounding
Safety Ground – (PE)
This is the safet y groun d f o r the dr ive that is re quired by code. One of thes e po ints must be connected to adjacent building steel (girder , joist), a floor ground rod or bus bar. Grounding points must compl y with national and local industrial safety regulations and/or electrical codes.
Shield Termination – SHLD
Either of the safety groun d terminals located on the po wer terminal block provides a grounding point for the motor cable shield.
The motor cable shield co nnected to one of these t erminals (drive end) sho uld also be connected to the motor frame (m otor end ) . Us e a shield terminating or EMI c lamp to connect the shie ld to t he s af ety ground terminal.
The conduit box option may be used with a cable clamp for a grounding point for the cable shield. When shielded cable is us e d f or c ontrol an d s ig nal w iri ng, th e s hi eld sh ou ld b e grounded at the source
end only, not at the drive end.
14
RFI Filter Grounding
Using single phase drives with integral filter, or an external filter with any drive rating, may result in relatively high ground leakage currents. Therefore, the filter must onl y be used in installations with grounded AC supply systems and be permanently installed and solidly grounded (bonded) to the building power distribution gr oun d.
Ensure that the incoming supply neutral is solidly connected (bonded) to the same building power distribution ground. Gr o und ing must not rely on flexibl e c abl es and should not incl ude any form of plug or socket that would permit inadvertent disconnection. Some local codes may require redundant ground connections. The integrity of all connections should be periodically checked.
Fuses and circuit breakers
The ILVFE drive does not prov ide branch short c ircuit pr otect ion. T his prod uct s houl d be ins talle d with either input fuses or an input circuit breaker. National and local industrial safety regulations and/or electrical codes may determine additional requirements for these installations.
ATTENTION: To guard against personal injury and/or equipment damage caused by improper fusing or circuit breaker selection, use only the recommended line fuses/circuit breakers specified in this section.

Power wiring
ATTENTION: National codes and standards and local codes outline provisions for
safely installing electrical equipment. Installation must comply with specifications regarding wire types, conductor sizes, branch circuit protection and disconnect devices. Failure to do so may result in personal injury and/or equipment damage.
ATTENTION: To avoid a possible shock hazard caused by induced voltages, unused wires in the conduit must be grounded at both ends. For the same reason, if a drive sharing a conduit is being serviced or installed, all drives using this conduit should be disabled. This will help minimize the possible shock hazard from “cross coupled” power leads.
Motor Cable Types Acceptable for 200-600 Volt Installations General
A variety of cable types are acceptab le for drive ins tallations . For m any installatio ns, unshield ed cable is adequate, provided it ca n be separated from sensitive circuits. As an approx imate guide, allow a spacing of 0.3 meters (1 foot) f or every 10 meters (32.8 f eet) of length. In all cas es, long parallel runs must be avoided.
Do not use cable with an insulation th ickness less than 15 m ils (0.4 mm/0.015 in.) . Do not route more than three sets of motor leads in a single conduit to minimize “cross talk”. If more than three drive/motor connections per conduit are required, shielded cable must be used.

Reflected wave protection
The drive should be ins talled as close to the motor a s possible. Installations with lo ng motor cables may require the addi tion of external devices to lim it voltage reflections at the motor (r eflected wave phenomena). See Table 1.E for recommendations.
The reflected wave data applies to all frequencies 2 to 10 kHz. For 240V ratings, reflected wave effects do not need to be considered.

* Longer cable lengths can be achieved by installing devices on the output of the drive. Consult factory for recommendations.
Output disconnect
The drive is intended to be commanded by control input signals that will start and stop the motor. A device that routinely disconnects then reapplies output power to the motor for the purpose of starting and stopping the motor should not be used.
If it is necessary to discon nec t pow er to th e m otor wit h the dri ve output ting p o wer, an aux iliar y contac t should be used to simultaneously disable drive control run commands.
Power terminal Block
The drive utilizes a finger guard over the power wiring terminals. To remove:
1. Press in and hold the locking tab.
2. For the finger guard on the top of the drive, slide it down and out.
For the finger guard at the bottom of the drive, slide it up a nd out. Replace the finger guard when wiring is complete.

* Maximum/minimum sizes that the terminal block will accept - these are not recommendations.
Motor start/stop precautions
ATTENTION: A cont actor or other device that ro utinely disconnects and reapplies
the AC line to the drive to start and stop the motor can cause drive hardware damage. The drive is desi gned to use control input signals that will st art and stop the motor. If used, the in put device must not exceed one operat ion per minute or drive damage can occur.
ATTENTION: The drive start/s top control circuitry inc ludes solid-state com ponents. If hazards due to acc idental contact with moving machiner y or unintentional flow of liquid, gas or solids exist, an additional hardwired stop circuit may be required to remove the AC line to t h e d rive. When the AC line is re moved, there will be a los s of any inherent regenerati ve braking ef fect that m ight be present - the motor will coast to a stop. An auxiliary braking method may be required.

I/O wiring recommendations
Important points to remember about I/O wiring:
• Always use copper wire.
• Wire with an insulation rating of 600V or greater is recommended.
• Control and signal wires should be separated from power wires by at least 0.3 meters (1 foot).
Important: I/O terminals labeled “Common” are not referenced to the safety ground (PE) terminal and are designed to greatly reduce common mode interference.
ATTENTION: Driv ing the 4-20mA analog input from a voltage source c ould cause component damage. Verify proper configuration prior to applying input signals.

common together for al l dr ives . If th e y ar e to be t ie d in to a noth er common (such as earth ground or separate apparatus ground) only one point of
the daisy chain of I/O Terminal 04 should be connected.
ATTENTION: Digital inputs on multiple drives should NOT be tied tog ether when using S NK (Internal Supp ly)
mode.
In SNK mode, if power is removed from one drive,
inadvertent operation of other drives that share the same I/O Common connection may occur.
