Standard Compliance
• To comply with PELV output requirements for EN/IEC 60204-1, ground the negative side of the output (-V) to a protective earth (PE).
• EN/IEC 61558-2-16
The S8VK-WA was designed based on EN/IEC 61558-2-16.
Currently, IEC 61558-2-17 has been replaced by IEC 61558-2-16.
When certification was received for EN/IEC 60204-1 (Machinery Safety), it was necessary to go through a control transformer to the control
circuits. However, a control transformer is not always necessary for product that have been certified for the safety standard for OVCIII or for
product that use a transformer that complies with EN/IEC 61558-2-16.
• Safety Standards for a DC Input
The following safety standards apply to a DC input: UL 62368-1, cUR (CSA C22.2 No. 62368-1), EN/IEC 62368-1, EN/IEC62477-1, EN/IEC
61558-2-16. Safety standard compliance is achievable by connecting a UL-certified fuse as specified below to the (L1/+) side.
For a DC power input, connect (L1/+) side to (+), and (L3/-) side to (-).
To select a UL certified fuse, refer to Recommended circuit breakers and fuses on page 25.

S8VK-WA S8VK-WB Common AccessoriesCommon Precautions
Inrush Current, Startup Time, and Output Hold Time
Note: Twice the normal inrush current will flow during parallel
operation or for backup operation. Therefore, check the fusing
characteristics of fuses and operating characteristics of
breakers making sure that the external fuses will not burn out
and the circuit breakers will not be activated by the inrush
current.
Overload Protection
The product is automatically protected from short-circuit current and
overcurrent damages when the load current is in the range of 151 to
175% of the rated current.
When the output current falls within the rated range, the overload
protection function is automatically cleared.
Note: 1. Internal parts may occasionally deteriorate or be damaged
if a short-circuited or overcurrent state continues during
operation. Be sure to check that the Iout > 100% indicator is
not lit or the Iout > 100% signal output is turned OFF before
using.
2. Internal parts may possibly deteriorate or be damaged if the
Power Supply is used for applications with inrush current or
overloading at the load end. Do not use the Power Supply
for such applications.
Overvoltage Protection
Overvoltage will be detected to prevent the load from being subjected
to excessive voltage when the feedback circuit in the Power Supply
fails, etc.
When an excessive voltage that is approximately 130% of the rated
output voltage or more is output, the output voltage is cut OFF,
preventing damage to the load due to overvoltage.
Reset the input power by turning it OFF for at least three minutes and
then turning it back ON again.
Note: Do not turn ON the power again until the cause of the
overvoltage has been removed.
INPUT OK Indicator
The INPUT OK indicator will light when the input voltage exceeds the
lower limit value of the permissible range.
Note: The voltage may be applied even if the indicator does not light.
Be sure to check the input voltage when performing wiring.
DC OK Indicator/Signal Output
The DC OK indicator will light when the output voltage is more than
90% of the rated output voltage, and the internal MOS FET relay is
conducted (turned ON).
Note: 1. The output voltage may be generated even if the indicator
does not light. Be sure to check the output voltage when
connecting to the load.
2. This function monitors the voltage at the power output
terminals.
To check the voltage accurately, measure the voltage at the
load end.
3. If the output voltage is set to less than 90% of the rated
output voltage, the indicator may go off and the signal
output may be turned OFF.
Iout > 100% Indicator/Signal Output
The Iout > 100% indicator lights up when the output current exceeds
the rated output current, and the internal MOS FET relay is conducted
(turned ON).
Note: 1. The Iout > 100% Indicator may light up, and the Iout > 100%
Signal Output may turn ON during peak current operation,
however, the Power Supply can be used as long as the
operating conditions specified in Peak current (P.27) are
satisfied.
2. Even when the operating conditions for parallel operation
are satisfied, the Iout>100% Indicator / Signal Output may
operate, so do not use the Iout>100% Indicator / Signal
Output.
3. During a short-circuit, the indicator will operate
intermittently due to the overload protection function. When
this happens, the indicator will blink in accordance with the
intermittent operation, and the Iout > 100% signal output will
repeated turn ON and OFF.
The shortest ON time of the Iout > 100% signal output
during intermittent operation is 5 ms.
Specifications of the Signal Output Terminals
(between DC OK Signal Output Terminal and
COM Terminal, and between Iout > 100% Signal
Output Terminal and COM Terminal)
Since the Signal Output is composed of the MOS FET relay, it does
not have any polarity.
30 VDC max., 50 mA max.
Residual voltage when the function is ON: 2 V max.
Leakage current when the function is OFF: 0.1 mA max.
Note: 1. Internal current control circuits are not provided internally
for output signals. Do not allow the output current to exceed
50 mA.
2. After completing wiring, confirm that the circuits operate
correctly.

Standard Compliance
• To comply with PELV output requirements for EN/IEC 60204-1, ground the negative side of the output (-V) to a protective earth (PE).
• EN/IEC 61558-2-16
The S8VK-WA was designed based on EN/IEC 61558-2-16.
Currently, IEC 61558-2-17 has been replaced by IEC 61558-2-16.
When certification was received for EN/IEC 60204-1 (Machinery Safety), it was necessary to go through a control transformer to the control
circuits. However, a control transformer is not always necessary for product that have been certified for the safety standard for OVCIII or for
product that use a transformer that complies with EN/IEC 61558-2-16.
• For the S8VK-WB, the DC input is not compliant with Safety standards.

S8VK-WA S8VK-WB Common AccessoriesCommon Precautions
Inrush Current, Startup Time, and Output Hold Time
Note: Twice the normal inrush current will flow during parallel
operation or for backup operation. Therefore, check the fusing
characteristics of fuses and operating characteristics of
breakers making sure that the external fuses will not burn out
and the circuit breakers will not be activated by the inrush
current.
Overload Protection
The product is automatically protected from short-circuit current and
overcurrent damages when the load current is in the range of 151 to
175% of the rated current.
When the output current falls within the rated range, the overload
protection function is automatically cleared.
Note: 1. Internal parts may occasionally deteriorate or be damaged
if a short-circuited or overcurrent state continues during
operation. Be sure to check that the Iout > 100% indicator
is not lit or the Iout > 100% signal output is turned OFF
before using.
2. Internal parts may possibly deteriorate or be damaged if the
Power Supply is used for applications with inrush current or
overloading at the load end. Do not use the Power Supply
for such applications.
Overvoltage Protection
Overvoltage will be detected to prevent the load from being subjected
to excessive voltage when the feedback circuit in the Power Supply
fails, etc.
When an excessive voltage that is approximately 130% of the rated
output voltage or more is output, the output voltage is cut OFF,
preventing damage to the load due to overvoltage.
Reset the input power by turning it OFF for at least three minutes and
then turning it back ON again.
Note: Do not turn ON the power again until the cause of the
overvoltage has been removed.
INPUT OK Indicator
The INPUT OK indicator will light when the input voltage exceeds the
lower limit value of the permissible range.
Note: The voltage may be applied even if the indicator does not light.
Be sure to check the input voltage when performing wiring.
DC OK Indicator/Signal Output
The DC OK indicator will light when the output voltage is more than
90% of the rated output voltage, and the internal MOS FET relay is
conducted (turned ON).
Note: 1. The output voltage may be generated even if the indicator
does not light. Be sure to check the output voltage when
connecting to the load.
2. This function monitors the voltage at the power output
terminals.
To check the voltage accurately, measure the voltage at the
load end.
3. If the output voltage is set to less than 90% of the rated
output voltage, the indicator may go off and the signal
output may be turned OFF.
Iout > 100% Indicator/Signal Output
The Iout > 100% indicator lights up when the output current exceeds
the rated output current, and the internal MOS FET relay is conducted
(turned ON).
Note: 1. The Iout > 100% Indicator may light up, and the Iout > 100%
Signal Output may turn ON during peak current operation,
however, the Power Supply can be used as long as the
operating conditions specified in Peak current (P.27) are
satisfied.
2. Even when the operating conditions for parallel operation
are satisfied, the Iout>100% Indicator / Signal Output may
operate, so do not use the Iout>100% Indicator / Signal
Output.
3. During a short-circuit, the indicator will operate intermittently
due to the overload protection function. When this happens,
the indicator will blink in accordance with the intermittent
operation, and the Iout > 100% signal output will repeated
turn ON and OFF.
The shortest ON time of the Iout > 100% signal output
during intermittent operation is 5 ms.
Specifications of the Signal Output Terminals
(between DC OK Signal Output Terminal and
COM Terminal, and between Iout > 100% Signal
Output Terminal and COM Terminal)
Since the Signal Output is composed of the MOS FET relay, it does
not have any polarity.
30 VDC max., 50 mA max.
Residual voltage when the function is ON: 2 V max.
Leakage current when the function is OFF: 0.1 mA max.
Note: 1. Internal current control circuits are not provided internally
for output signals. Do not allow the output current to exceed
50 mA.
2. After completing wiring, confirm that the circuits operate
correctly.
