OPERATING PRECAUTIONS

(1) Handling and installation

Handle according to the weight of the product.

Do not stack the inverter boxes higher than the number recommended.

Install according to instructions specified in this manual.

Do not open the cover during delivery.

Do not place heavy items on the inverter.

Check the inverter mounting orientation is correct.

Do not drop the inverter, or subject it to impact.

Use the Type 3 grounding method for 220 V class and special Type 3 for 440V class.

(Ground impedance: Below 100 ohm).

Take protective measures against ESD (Electrostatic Discharge) before touching the

PCB for inspection or installation.

Use the inverter under the following environmental conditions:

Ambient temperature

Relative humidity

Storage temperature

- 10 ~ +50℃ (non-freezing)

90% RH or less (non-condensing)

- 20 ~ +60℃

Location

Altitude,

Vibration

Protected from corrosive gas, combustible gas, oil mist or dust

Max. 1,000m above sea level, Max. 9.8m/sec

(1.0G) or less

(2) Wiring

Do not connect a power factor correction capacitor, surge suppressor, or RFI filter to

the output of the inverter.

The connection orientation of the output cables U, V, W to the motor will affect the

direction of rotation of the motor.

Incorrect terminal wiring could result in the equipment damage.

Reversing the polarity (+/-) of the terminals could damage the inverter.

Only authorized personnel familiar with RICH ELECTRIC inverter should perform wiring and inspections.

(3) Test run

Always install the inverter before wiring. Otherwise, you may get an electric shock or have bodily injury.

Check all constants during operation. Changing constant values might be required depending on the load.

Always apply permissible range of voltage to the each terminal as indicated in this manual. Otherwise, it could lead to inverter damage.

(4) Operation precautions

When the Auto restart function is selected, stay away from the equipment as a motor will restart suddenly after an alarm stop.

The “Stop” key on the keypad is valid only when the appropriate function setting has been made. Prepare an emergency stop switch separately.

If an alarm reset is made with the reference signal present, a sudden start will occur.

Check that the reference signal is turned off in advance. Otherwise an accident could occur.

Do not modify or alter anything inside the inverter.

Motor might not be protected by electronic thermal function of inverter.

Do not use a magnetic contactor on the inverter input for frequent starting/stopping of the inverter.

Use a noise filter to reduce the effect of electromagnetic interference. Otherwise

nearby electronic equipment may be affected.

In case of input voltage unbalance, install AC reactor. Power factor capacitors and generators may become overheated and damaged due to potential high frequency noise transmitted from inverter.

Use an insulation-rectified motor or take measures to suppress the micro surge voltage when driving 440V class motor with inverter. A micro surge voltage attributable to wiring constant is generated at motor terminals, and may deteriorate insulation and damage motor.

Before operating unit and prior to user programming, reset user constants to default settings.

Inverter can easily be set to high-speed operations, verify capability of motor or machinery prior to operating unit.

Stopping torque is not produced when using the DC-Break function. Install separate equipment when stopping torque is needed.

(5) Fault prevention precautions

(6) Maintenance, inspection and parts replacement

Provide a safety backup such as an emergency brake which will prevent the machine and equipment from hazardous conditions if the inverter fails.

Do not conduct a megger (insulation resistance) test on the control circuit of the inverter.

Refer to Chapter 5 for periodic inspection (parts replacement).

(7) Disposal

Handle the inverter as an industrial waste when disposing of it.

(8) General instructions

Many of the diagrams and drawings in this instruction manual show the inverter without a circuit breaker, a cover or partially open. Never run the inverter like this.

Always place the cover with circuit breakers and follow this instruction manual when operating the inverter.

Grounding

WARNING

Normal stray capacitance between the inverter chassis and the power devices inside the inverter and AC line can provide a high impedance shock hazard. Do not apply power to the inverter if the inverter frame is not grounded.

▇ Precautions on Wiring

□ The internal circuits of the inverter will be damaged if the incoming power is connected and applied to output terminals (U, V, W).

□ Use ring terminals with insulated caps when wiring the input power and motor wiring.

□ Do not leave wire fragments inside the inverter. Wire fragments can cause faults, breakdowns, and malfunctions.

□ For input and output, use wires with sufficient size to ensure voltage drop of less than 2%.

Motor torque may drop if operating at low frequencies and a long wire run between inverter and motor.

□ When more than one motor is connected to one inverter, total wiring length should be less

than 100m. Do not use a 3-wire cable for long distances. Due to increased leakage

capacitance between wires, over-current protective feature may operate or equipment

connected to the output side may malfunction.

□ Please reduce the constants of F46 Carrier frequency to prevent the current leakage when the wiring between the inverter and the motor is longer.

□ The main circuit of the inverter contains high frequency noise, and can hinder communication equipment near the inverter. To reduce noise, install RFI filters or line noise filters on the input side of the inverter.

□ Do not use power factor capacitor, surge suppressors, or RFI filters on the output side of the inverter. Doing so may damage these components.

□ Always insure the CHARGE LED lamp for the power terminal are OFF before wiring terminals. The charge capacitor may hold high-voltage even after the power is disconnected.

Use caution to prevent the possibility of personal injury.

▇ Grounding

□ The inverter is a high switching device, and leakage current may flow. Ground the inverter

to avoid electrical shock. Use caution to prevent the possibility of personal injury.

□ Connect only to the dedicated ground terminal on the inverter. Do not use the enclosure or a

chassis screw for grounding.

□ Grounding wiring should be as thick as possible. Grounding wire should be as short as

possible and should be connected to the ground point as near as possible to the inverter.

□ The correct grounding is essential when using the inverter. 220V class: less than 100Ω. 440V

class: less than 10Ω.

□ The grounding of the inverter should be separate from the grounding of welder.

□ Please refer to the below grounding method when there are multiple inverters used.

▇ Wiring and Terminal Screw Sizes

Refer to the following table for wires and terminal specification of the inverter power input

Power supply must be connected to the

R/L1, S/L2, and T/L3 terminals.

Connecting it to the R/L1, S/L2, T/L3 terminals causes internal damages to the inverter.

Arranging the phase sequence is not necessary.

Motor should be connected to the U/T1,

V/T2, and W/T3 terminals.

If the forward command (S1) is on, the motor should rotate clockwise when viewed from the load side of the motor. If the motor rotates in the reverse, switch the

U/T1 and V/T2 terminals.

Increasing voltage of V/F pattern increase motor torque, but an excessive increase may cause :

(1) motor overexcitation to damage inverter.

(2) motor overheat or vibration so slowly increasing voltage and monitoring on motor current is suggested.

Full-range Automatic Torque Boost

Motor torque requirement changes according to load conditions. Full-range automatic torque boost adjusts voltage of V/F pattern according to the requirement. EI-450M automatically adjusts the voltage during constant-speed operation as well as acceleration. The required torque is calculated by the inverter and this enasures triples operation and energy-saving effects.

Output voltage α Torque compensation gain (F63) × Required torque

Operation

Normally, no adjustment is necessary for torque compensation gain (F63). When the wiring distance between the inverter and the motor is long, or when the motorgenerates vibration, change the automatic torque boost gain.

In these cases, set the V/F pattern (F09 to F15).

The electronic thermal overload function monitors motor temperature, based on inverter output current and time, to protect the motor from overheating. When electronic thermal overload relay is enabled, an “OL1” error occurs, shutting OFF the inverter output and preventing excessive overheating in the motor. When operating with one inverter connected to one motor, an external thermal relay is not needed. When operating several motors with one inverter, install a thermal relay on each motor.

General-purpose Motor and Inverter Motor

Induction motors are classified as general-purpose motors or inverter motors, based on their cooling capabilities. Therefore, the motor overload function operates differently between these two motor types.

CHAPTER 6 FAULT DIAGNOSIS

▇ Protective and Diagnostic Functions

This section describes the alarm and fault displays, the fault conditions, and the corrective actions to be taken if the EI-450M malfunctions.

Inverter alarms are classified into alarm display and fault display.

Alarm display: When a minor fault occurs in the inverter, the Digital Operator flashes the

display. In this case, the operation is continued, and restored automatically as

soon as the cause is removed. Multi-function output can output the minor

fault status to external devices.

Fault display: When a major fault occurs in the inverter, the protective function operates,

and the Digital Operator lights the display and shuts off the output to stop the

inverter. The fault can be output as a fault output to the external devices by

multi-function output.

STOP

To reset the fault, use key of Digital Operator or cycle the power after taking the second corrective action.
