Thank you very much for purchasing this Shimaden product.

 

Make sure that the delivered product is the one that you ordered. Carefully read and fully understand this Instruction Manual before use.

 

For the communication function, refer to the separate PAC46 SERIES COMMUNICATION INTERFACE INSTRUCTION MANUAL.

 

Notice

 

Ensure that this manual is handed to the final user of the instrument. 

Introduction

 

This Instruction Manual is written for people who are involved in the installation, wiring, operation, and daily maintenance of the PAC46 series 
(hereinafter referred to as “the instrument”).

 

Use the instrument as a built-in component for industrial-use controllers.

 

Because this manual describes precautions, installation procedures, and wiring information, which are necessary to use the instrument, always 
keep it at hand during use.

 

Always operate 

t

he instrument according to the instructions contained in this Instruction Manual. Failure to follow the instructions in the 

Instruction Manual may impair the safety of the product.

 

Note that safety precautions, precautions for equipment and facility damage prevention, and additional explanations and notes on exceptions 
are given under the following headings.

 

 

ٵ

Failure to comply may result in personal injury or death. 

  WARNING

 

ٵ

Failure to comply may result in damage to equipment and/or facilities. 

  CAUTION

 

ٵ

Additional explanations, notes on exceptions, and other necessary information. 

NOTE

 

 

  WARNING

 

 

 

 

The PAC46 series is designed for the purpose of controlling the power of heaters and other facilities for industrial use. Never use it for a nuclear 

power plant, transportation, communication, medical care, or other critical facilities. If it is anticipated that a failure of this instrument or peripheral 

equipment can lead to a significant loss, be sure to take appropriate safety measures before use.

 

Please understand that we assume no responsibility for any accident that may occur as a result of use without safety measures.

 

 

 

  WARNING

 

 

 

 

1. 

Do not use the instrument as a switching device. Since the output circuit is continuous through capacitors and resistors even when the output is 

zero, there is a risk of electric shock, which may cause fatal or serious injury.

 

2. 

Radiator fins and the housing become hot when power is supplied. Never touch them. There is a risk of burn injury if you touch them.

 

3. 

Never perform wiring when power is supplied. Electric shock may result.

 

4. 

Be sure to ground the earth terminal.

 

5. 

Do not touch terminals and other live parts with your hands when power is supplied. In addition, do not put foreign objects inside the instrument. If a 

foreign object gets inside by accident, be sure to turn off the power supply and ensure safety before attempting to remove the foreign object with your 

hand or a tool.

 

 

 

  CAUTION

 

 

 

 

Use the instrument according to this Instruction Manual. Failure to follow the instructions in this Instruction Manual may impair the protection 

performance of the instrument.

 

If there is a possibility that a failure of the instrument may cause damage and/or loss of peripheral equipment, facilities, or products, provide, on the 

power supply input side, safety measures such as a rapid fuse, circuit breaker, earth leakage breaker, electromagnetic switch, and overheat 

prevention device for short-circuit protection and overload protection.

 

If an electromagnetic switch is used, surge noise may be generated during switching operation, which has a negative effect on the instrument. The 

instrument tends to malfunction, particularly in circuits to which an inductive load is connected. In such a case, we recommend using a noise filter, or 

connecting a class-X capacitor (about 0.1 to 0.5 μF) between each phase of the main power supply, or a class-Y capacitor (about 1000 to 3300 pF) 

between each phase of the power supply and ground, to absorb noise.

 

 

 

  CAUTION

 

 

 

 

1. 

About the alert symbol 

  The instrument has the alert symbol 

  printed on it. This is intended to alert the user of the risk of electric shock 

from touching live parts of the instrument when power is supplied, and the risk of burn injury from touching hot parts of instrument when power is 

supplied or immediately after power is cut off.

 

2. 

For any external power circuit connected to the instrument, provide a switch or circuit breaker as a means of turning off the power supply. The 

switch or circuit breaker should be installed in a location near the instrument for ease of operation. Put a label on the switch or circuit breaker 

saying that it is a power cut-off device for the instrument.

 

3. 

Tighten leads securely at the connecting points. Insufficient tightening may cause overheating due to contact resistance, which can result in 

burnout.

 

4. 

Use the instrument at or below the rated supply voltage and power supply frequency.

 

5. 

Do not apply non-standard input voltage or current to input terminals. Doing so not only shortens the product service life, but also may cause 

failure or damage of the instrument.

 

6. 

Use the loads connected to output terminals at or below the rated voltage or current. 

 

Exceeding the rated voltage or current not only shortens the product service life, but also may cause failure or damage of the instrument.

 

7. 

After wiring, be sure to install the supplied terminal cover before using the instrument.

 

8. 

Never modify or use the instrument for irregular applications.

 

9. 

To ensure safety and maintain the functions of this device, do not disassemble this device other than replacing the fuse.

If this device must be disassembled for replacement or repair, contact your dealer.

 

10. 

In order to use the instrument correctly and maintain the reliability of the instrument, follow the precautions provided in this Instruction Manual.

 

11. 

If the instrument has the communication function, and data is written from the master equipment, trimmer adjusters and control input terminals 

may be disabled, making output adjustment by the trimmer adjusters or by input signals from the control input terminals impossible. To be 

prepared in case the communication settings are incorrect, provide safety measures, such as a circuit breaker, on the power supply input side 

before using the instrument. Data written by the master equipment is retained even after power is cut off. Write data carefully to prevent incorrect 

communication settings. To enable input to trimmer adjusters and control input terminals, you need to write and then set the data again from the 

master equipment.

 

Note: Please understand that we assume no responsibility and warranty for any accident and/or injury that may occur as a result of failure to observe the 

warnings and precautions provided in this Instruction Manual.
