Preface
This instruction manual is written for people involved with PAC30Z-Series wiring, installation, operation, and daily
maintenance.
This instruction manual describes precautions, mounting methods, and wiring for the PAC30Z Series, so always keep it in a
convenient location when handling the PAC30Z Series.
Also, be sure to observe the contents described in this instruction manual. Precautions regarding equipment and facility
damage and safety precautions are listed under the following headings.
"
WARNING"
Precaution that may lead to injury or death if not followed
"
CAUTION"
Precaution that may lead to damage to equipment or facilities if not followed
1. Place this device in a control panel or other location. Do not allow your body to touch the terminals during use.
2. Do not use this device as a switch.
Even if the output is zero, the output circuit is charged through a capacitor/resistor, and there is a risk of fatal accident
or serious injury due to electric shock.
3. Radiator fins can become extremely hot. Never touch them.
Touching a radiator fin may cause burns or an electric shock.
4. Do not turn on the device when wiring. Doing so may cause an electric shock.
5. For models with a grounding terminal, be sure to ground the grounding terminal.
6. Do not touch the terminals or other charged parts while the power is on. Do not allow any foreign objects to enter the
product. Be sure to turn off the power and ensure your safety before inserting tools or hands in the machine if they have
accidentally entered.
1. Install a switch or circuit breaker in the external power supply circuit connected to the power supply terminal of the
device as a means to disconnect the power supply. Install and fix the switch or circuit breaker in a position close to the
device where it can be easily used by the operator and put a label to indicate that it is a power disconnect device for
the device.
2. Securely tighten all wiring connections. Insufficient tightening may cause overheating due to contact resistance, which
could lead to a burnout accident.
3. For models with a cooling fan, keep your hands and other objects away from the rotating fan blades.
4. Use this device within the rated power supply voltage and frequency.
5. Do not apply non-standard input voltage or current to the input terminals.
Failure to comply may shorten the product life or cause damage to the device.
6. Ensure that the voltage and current of the load connected to the output terminal are within the ratings. If the ratings
are exceeded, the temperature will rise, the product life may be shortened, and the device may be damaged.
7. Be sure to install the included terminal cover after wiring.
8. The user must not modify the product or use it irregularly under any circumstances.
9. To use this device safely and correctly and to maintain its reliability, please follow the precautions described in this
instruction manual.
NOTE: Shimaden shall not be liable or compensate for any accident or injury caused by failure to follow the warnings and
cautions in this manual.
