 Drop in supply voltage

• When the supply voltage drops, the KV Series stops operating and the output turns off.

 Detection of instantaneous power interruption

• An AC type basic unit continues operating against instantaneous power interruption of
less than 40 ms. A DC type basic unit continues operating against instantaneous power
interruption of less than 2 ms.

• An AC type basic unit may or may not accept instantaneous power interruption of 40 ms
or more. A DC type basic unit may or may not accept instantaneous power interruption
of 2 ms or more.

• When accepting instantaneous power interruption, a basic unit stops operating and the
output turns off.

 Automatic recovery

• Once the supply voltage recovers, the KV Series restarts operation automatically.

The maximum output capacity available with the AC type service
power output is the output capacity of each basic unit subtracted by
the internal current consumption of the basic unit, connected
expansion units, and connected peripheral units.

If the supply voltage increases gradually or drops, the KV Series may repeat
operation and then stop. If problems continue to occur with equipment and
other operations from repetitive starts and stops, provide a protection circuit
so that the output shuts down until the voltage reaches the rated value.

Installation Environment

 Installation environment

• Locations exposed to direct sunlight

• Locations whose ambient temperature is outside the allowable range of 0 to +50°C (32
to 122°F) (No freezing)

• Locations whose ambient humidity is outside the allowable range of 35 to 85% RH (No
condensation)

• Locations subject to drastic temperature change where condensation may occur

• Locations with corrosive or flammable gases

• Locations with excessive dust, salt, iron powder, or soot

• Locations subject to direct vibrations and impacts

• Locations subject to splashes of water, oil, chemicals, etc.

• Locations where a strong magnetic or electrical field is generated

Units are made of synthetic resin. If the unit surf ace touches a solvent with a strong
dissolving force, it could melt. Keep such solvents away from the units.

.

Installation Position

 Installation direction

When attaching a unit inside a panel, install the unit so that the front face (equipped with the
access window, communication ports, etc.) faces front or upward.

 Distance between adjacent panels/equipment

When installing a unit, keep the distances shown on the right
between the panel or equipment so that the power suppl y can
release heat.

• If the temperature inside the panel exceeds 50°C (122°F), which is
specified as the maximum ambient operating temperature, then
install heat exchangers, etc. to reduce the temperature.

• Ensure sufficient ventilation space so that the power supply can
release heat.

• Never install a unit just above any equipment which generates a lot
of heat.

Installation Procedure

This section describes how to attach a connected unit directly to a
panel, to a DIN rail, or to a DIN rail with an expansion unit spacer.

 Attaching a unit directly to a panel

Attach a metal fixture for screw tightening to a KV Series basic unit
with set screws. Then, attach the basic unit with a metal fixture
directly to the panel.

 Attaching a unit to a DIN rail

Hang an upper claw of a KV Series basic unit to the upper side of
the DIN rail, and press the basic unit onto the DIN rain until a click
sound is heard.

 Removing a unit from a DIN rail

Pull a lower claw of a KV Series basic unit downward from the
front direction using a screwdriver, and then remove the basic unit
from the DIN rail.

This section describes cautions to keep in mind when wiring is performed for I/O units. Be
sure to read this section before starting wiring.

 Wiring procedures for basic units

The wiring procedures for basic units are described below.

• Turn off the power before starting wiring.

• For the installation position, select a location whose ambient
temperature is 0 to +50°C (32 to 122°F) (No freezing), whose
ambient humidity is 35 to 85% RH (No condensation), and one
which is not subject to drastic temperature changes.

• If the 24 V DC + output terminal and the 24 V DC - output terminal
are switched, the power supply unit and connected units may be
damaged. Never switch them.

• Be sure that the sum of the current consumption of all connected
units does not exceed the output capacity of the service power
supply. If the system is operating in an overload status, the internal
circuits may generate heat or be damaged. To recover from an
overload status, disconnect some of the connected units.

• Never connect the DC output of any other power supply, either in
serial or parallel, to the 24 V DC output terminals. If the DC output is
connected, the power supply unit may be damaged.

 Wiring for an AC type basic unit

For an AC type basic unit, perform the wiring as shown in the figure below.

• Connect an insulating transformer (1:1) or noise filter to reduce line noise.

• Use twisted cables to reduce induction effects.

• When using a basic unit in a location with a lot of noise, the noise
may be reduced by using completely grounding the basic unit.

 Wiring for a DC type basic unit

For a DC type basic unit, perform the wiring as shown in the figure below.

Contact Protection

If inductive loads such as clutches, motors, and solenoids are used, a rush current may flow
when the load power supply is turned on, or a counter electromotive voltage may be
generated when the load power supply is shut down. The rush current and the counter
electromotive voltage can contribute considerably to shortening the service life of the
contacts. To prevent this from happening, provide a contact protection circuit.

Part Names and Functions

• Connect the power supply to the power supply input terminals with
24 VDC output, which offers a sufficient margin of power capacity.
Usually, the sum of the current consumption of all connected units
multiplied by 1.5 or more is required for the power capacity.

• To reduce line noise, insert a ferrite core.

 Cautions on wiring for I/O units

When performing wiring for an I/O unit, pay strict attention to the following contents.

• Separate input lines from output lines in wiring.

• If the wiring for power is located near I/O signal lines, a malfunction may occur caused
by the effects of a high voltage and large current.

• Keep I/O signal lines away from the power wiring by at least 100 mm.

• Separate 24VDC I/O lines from 100 VAC and 200 VAC lines.

• When using pipes for wiring, make sure that the pipes are securely grounded.

When I/O signal lines cannot be separated from the wiring for power

In such a case, perform grounding on the KV side using batch-shielded cables. (In some
environments, grounding should be performed on the reverse side of the KV.)

 Term inal

The terminal screws used are M3. When performing wiring with crimp-style terminals, use
the following ones.

 Cautions on grounding

Because the KV Series is constructed to be sufficiently resistant to noise, it can usually be
used without being grounded. However, when the KV Series is used in an environment with
a lot of noise, grounding is required. In such a case, pay strict attention to the following
contents.

• Perform completely grounding for each individual unit. In this case, the ground
resistance should be 100 ¾ or less.

• If individual grounding is not possible, perform common grounding. In this case, the
length of each grounding cable should be equal.
