Wiring
• Wire it after all the powers of the instruments are shut off.
•It works at 24 V DC. When using a power other than the rating, it may cause an electric shock and fire.
•When connecting many of ML Series to make one module, connect a power to only one unit.
• When connecting to 24 V DC power, use it in accordance with the rating after calculating total
consumption of electric power. Using a power supply of lower capacity than the total
consumption of electric power of the module may cause malfunction of the product.
• Do not work with wet hand. It may cause electric shock.
• For installation and way of use, use the manual and follow it.
• Refer to the installation method for the content and about the connection. Never connect to
gas pipe, telephone wire, and lighting rod. It may cause explosion and fire.
•Do not supply power before finishing the connections among the parts of this product.
• There is a possibility of electric shock while applying electric current. So, do not come in contacts with any parts.
• For I/O signal line, wire it after separating the instrument's power line and load line to
prevent the impact of induction noise.
•For instrument's power, wire it to avoid a noise impact from the power. We recommend
to use noise filter if it is easy to get impact of the noise.
•For connected module's power supply, supply it to only one module. Power is supplied
among all connected modules.
•For power, select the product in accordance with inrush current when the connected
module's consumption voltage and Power are ON.
