[Precautions for wiring]
Tighten the terminal screws within the specified torque range. Loose tightening of the terminal
screws may result in short-circuit, fire or malfunction. Excessive tightening of the terminal screws
may cause damage to the screws or unit, resulting in dropping, short-circuit or malfunction.
Be careful to prevent foreign matter such as cutting chips and wiring offcuts from entering into the
unit.
Fire, failure or malfunction may result.
On the upper part of the units, protective labels are provided to prevent foreign matter, such as
chips of wires and shields, entering inside the units during the wiring operation. Do not remove
those labels until the wiring is complete.
To ensure proper heat radiation, confirm that those labels are removed prior to operating the
system.
Incorrect wiring may damage the equipment. Be careful with regard to the label length and layout
so that connectors and electric wires are not disconnected.
When connecting wires with terminal blocks, do not solder. A contact failure may result.
If wiring for the power line is long, power voltage for the remote slave unit may become insufficient
due to voltage drop. Therefore, connect an external power source to ensure the specified voltage.
Do not turn on the 24 V DC power source before completing wiring and connections of the whole
Anywire system.
Use a 24 V DC direct current stabilized power supply for Anywire system devices.
Do not bind the control wire and communication cable with the main circuit or power line, or do not
bring them close to each other. Noise may result in malfunction.
Make sure to put electric wires and cables to be connected to the unit into ducts or fix them with
clamps. Unless cables are put into ducts or fixed with clamps, drift, movement or careless
tensioning of a cable may result in damage to the unit or cable, and a connection failure of a cable
may result in malfunction.
When removing cables connected to the unit, do not hold the cable section by hand when pulling.
Remove the cable equipped with a connector by holding the connector on the connection part of
the unit.
To remove cables connected to the terminal blocks, loosen the terminal screws on the terminal
block. When cables are pulled while they are connected to the unit, malfunction or damage of the
unit or cable may result.
