Instruction manual
To prevent accidents arising from the misuse of this controller, please ensure the operator receives this manual.
SAFETY PRECAUTIONS
Be sure to read these precautions before using our products.
The safety precautions are classified into categories: "Warning" and "Caution".
Warning : Procedures which may lead to dangerous conditions and cause death or serious injury, if not
carried out properly.
Caution : Procedures which may lead to dang erous conditions and cause superficial to medium injury
or physical damage or may degrade or damage the product, if not carried out properly.
• When using this controller on occasions which serious injury would be expected to occur or when damage is
likely to expand or proliferate, make sure to take safety measures such as installing double safety structures.
• Do not use this controller in an environment with flammable gases, or it may cause explosion.
• Fasten the electric wire with the t erminal screws securely. Imperfect connection m ay cause a bnormal
heating or fumes.
• Use this controller according to the rating and environmental conditions. Otherwise a bnormal heating or
fumes may occur.
• Do not touch the terminals while t he power is supplied to the controller, as this may ca use electric shock.
• Do not disassemble or modify the controller, as this may cause electric shock or fumes.
Caution
• This instrument should be used in accordance with the specifications described in the manual.
If it is not used according to the specifications, it may malfunction or cause fire.
• Be sure to follow the warnings, cautions and notices. Not doing so could cause serious injury or accidents.
• The contents of this instruction manual are subject to change without notice.
• This instrument is designed to be installed in a control panel. If not, measures must be taken to ensure
that the operator cannot touch power terminals or other high voltage sections.
• Be sure to turn the power supplied to the instrument OFF before cleaning this instrument.
• Use a soft, dry cloth when cleaning the instrument.
(Alcohol based substances may cause tarnishing or defacement of the unit)
• As the display section is vulnerable, do not strike or scratch it with a hard object.
• Any unauthorized transfer or copying of this document, in part or in whole, is prohibited.
• Matsushita Electric Works, Ltd. is not liable for any damage or secondary damage(s) incurred as a result
of using this product, including any indirect damage.
• To pull out the inner assembly, release the hooks at the top and bottom of the instrument with thin, hard
tweezers. (If the hooks are released too far, they may break, or IP 66 function could deteriorate.)
Do not pull out the inner assembly except when repairing the instrument.)
