Observe the following precautions to ensure safety.
(1) Maintain the power supply voltage within specifications.
(2) Use the product within the rated load.
(3) Be sure to check each terminal for correct number and polarity before connection.
Incorrect or reverse connection may damage or burn out internal components of the product.
(4) Be sure to tighten the terminal screws.
Recommended tightening torque: 0.43-0.58 N·m
Loose screws may result in product failure or malfunction.
(5) Do not connect anything to unused terminals.
(6) Install a switch or a circuit breaker so that the operator can turn off the power supply without delay
and attach an appropriate label.
(7) Do not disassemble, repair, or modify the product.
(8) Do not use the product in flammable or explosive atmosphere.
(9) For the wiring, use wires that can withstand a temperature of 70°C or higher.
(10) For the crimp terminals for crimp terminal wiring connections, use the specified size (M3, width of
5.8 m or less). For wiring for bare-wire connections, use AWG22 to AWG14 for the power supply,
and AWG28 to 16 for other than the power supply. (Wire jacket strip length: 6 to 8 mm)
(11)Let the product warm up at least 15 minutes after turning on the power.
For proper usage of the product:
(1) Do not use the product in such an environment that is subject to the following:
• Direct heat radiation from any heat source
• Water flooding or oil splashes
• Direct sunlight
• Dust or corrosive gases (especially, sulfuric or ammonia gas)
• Rapid temperature changes
• Condensation or icing due to high humidity
• Strong vibration or mechanical shock
(2) Do not block heat dissipation from the product, i.e., allow sufficient space for heat dissipation.
(3) Be sure that the rated voltage is reached within 2 seconds after the power is turned ON.
(4) Conduct aging for at least 15 minutes after turning ON the power for correct measurement.
(For K3MA-L: 30 minutes)
(5) To prevent the effect of static electricity, do not touch live terminals or slit areas of the product.
(6) Do not apply heavy load to the product. Doing so may deform or deteriorate the product.
(7) Do not use paint thinner for cleaning. Use commercially available alcohol.
Installation and connection
(1) Mount the product to a panel that is 1 to 8 mm thick.
(2) Install the product in a horizontal position.
(3) Use crimp-style terminals fit for the screw size.
