D
anger
・Shut off the external power supply for the unit in all phases before installing or wiring. Failure to do so may cause an electric shock or damage of this unit.
・Work under the electric outage condition when installing and wiring. Failure to do so may cause electric shock, a failure of the unit, a fire etc.
・When tapping or wiring, take care not to entering any foreign objects such as chips and wire pieces into this unit.
・Check the connection diagram when wiring. Wrong wiring may cause failure of the unit, a fire or electric shock.
・For protection against noise, transmission lines and input/output lines shall not be placed close
to or bound together with the power lines and high-voltage lines.
・Strip the wires with proper length. Overlong stripping length may cause short to next wire. Shorter stripping length may cause contact failure.
・Take care not to short to next terminal by a filament.
(
Do not plate the wires with solder.
)
・Do not connect more than two wires to one terminal of a terminal block for preventing loose contact and wires dropout.
・Use appropriate size of electric wires. If inappropriate size of electric wire is used, it may cause a fire due to
generated heat.
・Tighten the screw within the specified torque. Under tightening can cause drop of the screw, short circuit or malfunction. Over tightening can damage the screw and/or unit, resulting in
drop, short circuit or malfunction.
・After tightening the screws, be sure to check all the screws tightened. Loose screw may cause malfunction of the unit, a fire or electric shock.
・Be sure to attach the terminal cover to prevent electric shock.
・Use the crimp-t
ype terminal appropriated for the size of electric wires. If inappropriate crimp-type terminal is used, a wire breakage or a contact failure may occur, which may cause a
device malfunction, a failure, a burnout or a fire.
・FG terminal must be grounded according to the D-type ground
(
ground resistance is not exceed 100Ω
)
.
