SHORT-CIRCUIT PROTECTION

٨

The power supply unit of this equipment adopts the electronic fuse which do
not require any replacement.

٨

When the electronic fuse is operated, turn off the power supply, and remove
the cause of overcurrent before restarting the power supply for resetting.
The electronic fuse is not suitable to use in which the equipment is operated

٨

continuously or daily. Note that operating the equipment continuously may
not be unable to satisfy the specifications.

CAUTIONS

٨

In case this unit is connected to a product other than the connectable input
devices, this unit doesn't meet the control category 4 specified in EN 954-1.
Connect this product and the light curtain to a common power supply.

٨

Make sure that the power is off while wiring.

٨

Take care that wrong wiring will damage the product.

٨

Verify that the supply voltage variation is within the rating. Take care that if a

٨

voltage exceeding the rated range is applied, or if an AC power supply is di­rectly connected, the unit may get burnt or damaged.
The DC power supply unit must satisfy the conditions given below:

٨

1) Power supply unit authorized in the region where this device is to be used.

2) Power supply unit conforming to EMC Directive and Low-voltage Directive
(In case CE conformity is required.)

3) Power supply unit conforming to the Low-voltage Directive and with an out­put of 100VA or less.

4)

The frame ground (F.G.) terminal must be connected to ground when using
a commercially available switching regulator.

5) Power supply unit with an output holding time of 20ms or more.

6) Use an isolation transformer for the DC power supply unit.

7) In case a surge is generated, take countermeasures such as connecting a
surge absorber to the origin of the surge.

8)

Power supply unit corresponding to CLASS 2 (In case C-UL conformity is required.)

<Additional information>
As provided in IEC 60536 (CLASS: Protection against Electric Shook), this
power supply should require no ground earth and satisfy the insulation dis­tance called double insulation or reinforced insulation.

In case the power supply conforms to Low-voltage Directive and has an
output of 100VA or less, it can be used as a suitable product.

Do not run the wires together with high-voltage lines or power lines or put

٨

them in the same raceway. This can cause malfunction due to induction.
Avoid dust, dirt, and steam.

٨

Take care that the product does not come in direct contact with water, oil,

٨

grease, or organic solvents, such as, thinner, etc.
The seal as shown in the drawing on the right is

٨

stuck to the engagement point of unit. When the
seal is peeled off or broken, this equipment will
not be certified as 'Safety equipment' and will not be covered by our guarantee.

٨

Note that this equipment is applicable only in the control circuit grounded in
accordance with IEC 60204-1 and JIS B 9960-1, or in the control circuit in
which the insulation monitor unit (ground fault detection unit) is arranged.
This unit is suitable for indoor use only.

I/O CIRCUIT DIAGRAM

٨

The following cables are recommended for power supply / output line and
signal line.
Solid wire: Ǿ0.4 to Ǿ1.2mm (AWG 26 to 16)
Twisted wire: 0.3 to 1.25mm2(AWG 22 to 16)
Standard stripped wire length: 11mm
For wiring the light curtain, refer to the instruction manual enclosed with the

٨

light curtain.
When connecting a product other than this product with the light curtain,

٨

arrange a terminal block separately.

<Wiring for the minus grounding (PNP setting)>

٨ The figure shown below is the case that this product is connected to a type 4

PNP output type light curtain. Connect the control output OSSD 1 and OSSD
2 of the light curtain to S1 and S2 respectively.

INSTALLATION POSITION/DIRECTION/METHOD

٨

Use the 35mm width DIN rail to install the unit.

٨

The installation position/direction is not
basically limited.
Please fix this product with the optional DIN rail

٨

stopper (MS-DIN-E) after installing the product
on to the 35mm width DIN rail.
If two, or more, units are placed side by side,

٨

make sure to space them at least 5mm apart. In
case they are mounted close to each other,
lower the rated operation current of the safety
output depending on the ambient temperature,
refering the right graph.
