Preface

Thank you for purchasing our EQ5 series inverter. This product is used to drive a 3-phase electric motor at

variable speed. As incorrect use of this product may result in personal injury and/or property damage,

please read all safety and operating instructions before using.

Safety Instructions

Please read this manual carefully before installing, connecting (wiring), operating, servicing, or inspecting the

inverter. Also please familiarize yourself with all safety features before using the inverter.

In this manual, safety messages are classified as follows:

Danger Improper operation may result in serious personal injury or death.

Caution Improper operation may result in slight to medium personal injury or property

damage.

Situations more serious than those covered by CAUTION will depend on prevailing circumstances.

Always follow instructions.

Instructions on use:

Danger

•This inverter is designed to drive a 3-phase induction motor and is not suitable for a single-phase motor or

any other types, as fire may result.

•This inverter may not be used (as is) as a component of a life-support system or other medical device

directly affecting the personal welfare of the user.

•This inverter is manufactured under strict quality control standards. However, safety equipment must be

installed if the failure of this device may result in personal injury and/or property damage.

•There is a risk of accident.

Instructions on installation:

Danger

•Mount this inverter on an incombustible material such as metal. There is a risk of fire.

•Do not place combustible or flammable material near this inverter, as fire may result.

Caution

•Do not hold or carry this inverter by the surface cover. Inverter may be dropped causing injury.

•Ensure that the inverter and heat sink surfaces are kept free of foreign matter (lint, paper dust, small chips

of wood or metal, and dust), as fire or accident may result.

•Do not install or operate a damaged inverter or an inverter with missing parts, as injury may result.

Instructions on wiring:

Danger

•Connect the inverter to power via a line-protection molded-case circuit breaker or fuse, otherwise fire may

result.

•Always connect a ground wire, otherwise electric shock or fire may result.

•A licensed specialist must perform the wiring, otherwise electric shock may result.

•Turn off the power before starting the wiring, otherwise electric shock may result.

•Wire the inverter after installation is complete, otherwise electric shock or injury may occur.

Caution

•Confirm that the phases and rated voltage of this product match those of the AC power supply, otherwise

injury may result.

•Do not connect the AC power supply to the output terminals (U,V,and W), otherwise injury may result.

•Do not connect a braking resistor directly to the DC terminals (P(+)and N(-)),otherwise fire may result.

•Ensure that the noise generated by the inverter, motor, or wiring does not adversely affect peripheral

sensors and equipment, otherwise accident may result.

Instructions on operation:

Danger

•Be sure to install the surface cover before turning on power (closed). Do not remove the cover while

power to the inverter is on. Otherwise electric shock may occur.

•Do not operate switches with wet hands, otherwise electric shock may result.

•When the retry function is selected, the inverter may restart automatically after tripping. Design the machine

to ensure personal safety in the event of restart. Accident may result.

•When the torque limiting function is selected, operating conditions may differ from preset conditions

(acceleration/deceleration time or speed). In this case, personal safety must be assured. Otherwise

accident may result.

•As the STOP key is effective only when a function setting has been established, install an emergency

switch independently, and when an operation via the external signal terminal is selected, the STOP key on

the keypad panel will be disabled. Otherwise accident may result.

•As operations start suddenly if an alarm is reset with a running signal input, confirm that no running signal

is input before resetting alarm. Otherwise accident may result.

•Do not touch inverter terminals when energized even if inverter has stopped. Otherwise electric shock

may result.

Caution

•Do not start or stop the inverter using the main circuit power. Failure may result.

•Do not touch the heat sink or braking resistor because they can be extremely hot. Burns may result.

•Carefully check the performance of motor or machine before operating at high speed. Injury may result.

•Do not use the inverter braking function for mechanical holding. Otherwise injury may result.

Instructions on maintenance, inspection, and replacement:

Danger

•Wait a minimum of five minutes (30HP/CT, 40HP/VT or less) or ten minutes (40HP/CT, 50HP/VT or more)

after power has been turned off (open) before starting an inspection. (Also confirm that the charge lamp is

off and that DC voltage between terminals P (+) and N (-) does not exceed 25V.) Otherwise electrical

shock may result.

•Only authorized personnel should perform maintenance, inspection, and replacement operations.(Take off

metal jewelry such as watches and rings and use insulated tools.) Otherwise electric shock or injury

may result.

Instructions on disposal:

Caution

•Treat as industrial waste when disposing it. Otherwise injury may result.

Other instructions:

Danger

•Never modify the product. Otherwise electric shock or injury may result.

Long-term Storage

If the product is to be stored for an extended period of time after purchase, the method of storage depends

primarily on storage location.

The general long-term storage method is as follows:

1. The above conditions for temporary storage must be satisfied.

When the storage period exceeds three months, the upper limit of ambient temperature must

be reduced to 30º (86ºF) to prevent the deterioration of the electrolytic capacitors.

2. Pack the product thoroughly to eliminate exposure to moisture and include a drying agent to

ensure a relative humidity of about 70% or less.

3. If the product is mounted on equipment or a control panel and is not being unused and is exposed to

the elements such as like moisture or dust (particularly on a construction site), remove the product and

store in a suitable environment.

4. Electrolytic capacitors not provided with voltage for extended periods of time will deteriorate. Do not

store electrolytic capacitors longer than one year without providing voltage to them.
