Product-specific cautions
■
Use power supply voltages and outputs within the
specified voltage.
If voltage exceeding the specified voltage is
applied, the product could malfunction or be
damaged, or electrical shock or fire could occur.
■
Check the connector pin and cable core wire color
when wiring. Incorrect connections could cause
product damage, problems, or malfunctions. Check
the wire color against instructions and precautions
before wiring.
■
Ensure that wires are properly insulated.
Check that wires do not come into contact with
other circuits, that no ground faults occur, and that
the insulator between terminals is not defective.
Otherwise, overcurrent may flow into the product,
causing damage.
■
Use a stabilized DC power supply within the
specified rating that has been insulated from the
AC power supply. A non-insulated power supply
could result in electrical shock. If power is not
stabilized, the peak value in hot summer could
exceed the rating and damage the product or
reduce precision.
■
Stop the control device and equipment and turn
power OFF before wiring. Starting operation
suddenly could cause unpredictable and dangerous
operation. First, conduct an energized test with
controls and machinery stopped, and set target
data. Be sure to discharge any accumulated
electrostatic charge among personnel, tools, or
equipment before and during work. Connect and
wire bending resistant material, such as robot wire
material for movable sections.
■
Do not use at levels exceeding the power supply
voltage range. The product could rupture or burn if
voltage exceeding the specification range or AC
power supply (100 VAC) is applied.
■
Install this product and wiring as far away as
possible from sources of noise such as power
distribution wires. Provide separate
countermeasures for surge applied to the power
cable.
■
L type cable connectors do not rotate.
Never attempt to rotate them.
■
Be sure to disconnect the power supply before
inserting/removing M12 connectors.
■
Always hold the connector part when inserting/
removing M12 connectors. Do not hold by the
cable to pull out.
■
When fitting the M12 connector, align the
protrusions on the main unit connector terminal with
the recesses on the cable connector terminal and
insert them securely, then hold the knurled part and
tighten it clockwise to avoid damaging the threads.
■
Take care as tightening with excessive force may
lead to damage of the body connector.
Recommended torque: 0.4 to 0.49 N·m
■
If extending the cable, use a wiring length of 20 m or
less between the master and device (this product).
■
Insulate wires not being used so that they do not
contact other wires.
Unintended connection of unused wires to the
ground, etc., could cause malfunction or damage to
the product.
DANGER
WARNING
CAUTION
1. Wiring
Mounting, installation and adjustment
■
The power supply for the stainless steel body is a
DC stabilized power supply completely isolated
from the AC primary side. Connect either the + side
or - side of the power to the FG. Between the
internal power circuit and stainless steel body, a
varistor (limit voltage approx. 40 V) is connected to
prevent dielectric breakdown of the product. Do not
conduct a withstand voltage test or insulation
resistance test between the internal power circuit
and stainless steel body. Disconnect wiring first if
this testing is required. An excessive potential
difference between power and stainless steel body
will burn internal parts.
After installing, connecting and wiring the stainless
steel body, electrical welding of the device/frame,
or short-circuit accidents, etc., could cause welding
current, excessive high voltage caused by welding,
or surge voltage, etc., to run through wiring, ground
wire, or fluid path connected between such
devices, damaging wires or devices. Conduct any
work such as electrical welding after removing this
device and disconnecting all electric wires
connected to the FG.
