S8VM_13 Datasheet, PDF (33/38 Pages) Omron Electronics LLC – Power Supply Featuring OMRON’s Unique, New Undervoltage Alarm Function with Compact Body Contributing to Machine Downsizing

Use the following material for the wires to be connected to the S8VM
to prevent smoking or ignition caused by abnormal loads.
Over heating or fire can result from inadequately sized wiring
materials when problems occur at the load. As a general rule, always
select wire sizes suitable for at least 1.6 times the rated current.
Refer to the wiring manufacturer's recommended allowable current
and voltage drop specifications for information when selecting wiring
materials.

The current rating for the output terminals on the S8VM-300@@C is
40 A per terminal. The current rating for the output terminals on the
S8VM-600@@C is 60 A per terminal. Use two terminals together if a
current exceeding the terminal rating is used.
Use min. 60°C or 60/75°C wire.
Use copper conductors only.

Be sure to prepare the connector according to the following instruc-
tions to ensure correct wiring. For details, refer to the JST catalog.
• Use a wire size of AWG28 to AWG22.
• The guideline for the length of sheath to be stripped from the wire is
2.1 to 2.6 mm.
• Use either a YC or YRS Crimping Tool (manufactured by JST) to
crimp the terminal and wire.
• Be sure to insert the crimped terminal wires into the housing fully
until a click is heard. Also, make sure that the wires attached to the
housing are securely locked in place.

Be sure to prepare the connector according to the following instruc-
tions to ensure correct wiring. For details, refer to the JST catalog.
• Use a wire size of AWG26 to AWG22.
• The guideline for the length of sheath to be stripped from the wire is
2.3 mm.
• Use a YC Crimping Tool (manufactured by JST) to crimp the termi-
nal and wire.
• Applicable wire per barrel size is UL1007 (standard wire) and its
equivalent standard wire can be used. Use UL1061 or its equiva-
lent standard wire for AWG22 wires, because the wire insulation
outer diameter of UL1061 is small.
• Be sure to insert the crimped terminal wires into the housing fully
until a click is heard. Also, make sure that the wires attached to the
housing are securely locked in place.
Installation Environment
Do not use the Power Supply in locations subject to shocks or
vibrations. In particular, install the Power Supply as far away as
possible from contactors or other devices that are a vibration source.
Install the Power Supply well away from any sources of strong, high-
frequency noise and surge.
Operating Life
The life of a Power Supply is determined by the life of the electrolytic
capacitors used inside. Here, Arrhenius Law applies, i.e., the life will
be halved for each rise of 10°C or the life will be doubled for each
drop of 10°C. The life of the Power Supply can thus be increased by
reducing its internal temperature.
Ambient Operating and Storage
Environments
Store the Power Supply at a temperature of −25 to 65°C and a
humidity of 25% to 90%.
The Internal parts may occasionally be deteriorated or damaged.
Do not use the Power Supply outside the derating range (i.e., under
conditions indicated by the shaded area (
) in the derating
curve diagrams on pages 9 and 15.)
Use the Power Supply at a humidity of 30% to 85%.
Do not use the Power Supply in locations subject to direct sunlight.
Do not use the Power Supply in locations where liquids, foreign
matter, or corrosive gases may enter the interior of the Power Supply.
Overload Protection
If the Power Supply has been short-circuited or supplied with an
overcurrent for longer than 30 seconds, the internal parts of the
Power Supply may occasionally be deteriorated or damaged.
Internal parts may possibly be deteriorated or damaged if the Power
Supply is used for applications with frequent inrush current or
overloading at the load end. Do not use the Power Supply for such
applications.
Dielectric Strength Test
If a high voltage is applied between an input and the case (PE/FG), it
will pass though the LC of the built-in noise filter and energy will be
stored. If the high voltages used for dielectric strength testing are
turned ON and OFF with a switch, timer, or similar device, impulse
voltage will be generated when the voltage is turned OFF and
internal parts may possibly be damaged. To prevent the generation
of impulse voltages, reduce the applied voltage slowly with a variable
resistor on the test device or turn the voltage ON and OFF at the
zero-cross point.
When performing the test, be sure to short-circuit all the output
terminals to protect them from damage.
Check the waveform of the applied voltage while testing. High
voltage due to distortions of the applied voltage may be produced
depending on the type of testing equipment.
