• Use the following material for the wires to be connected to the
S8VS to prevent smoking or ignition caused by abnormal loads.
Recommended Wire Type
15-W and 30-W Models
60-W, 90-W, 120-W, 180-W, 240-W, and 480-W Models
• Strip I/O wires for 11 mm when using a screwless terminal block.
* The rated current for output terminals is 10 A per terminal. Be sure
to use multiple terminals simultaneously for current that exceeds
the terminal rating. When applying a current of 10 A or more, use at
least two terminals each for the positive and negative wires.
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 cut in half 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%.
• Do not use the Power Supply in areas outside the derating curve
otherwise, internal parts may occasionally deteriorate or be
damaged.
• Use the Power Supply at a humidity of 25% to 85%.
• Do not use the Power Supply in locations subject to direct sunlight.
• Do not use locations where liquids, foreign matter, or corrosive
gases may enter the interior of Products.
S8VS-@@@24A@@ Models only
Satisfy the following conditions when storing the Power Supply for
long periods of time to maintain its remaining service life function.
When storing for more than three months, store within an ambient
temperature range of −25 to +30°C and the humidity range of 25% to
70%.
Periodic Check for Models with Indication
Monitor Except 60-W Models
It may take from several years to more than 10 years under general
operating conditions for the power supply to output the maintenance
forecast monitor alarm (S8VS-@@@24A@@). The total run time
monitor (S8VS-@@@24B@@/S8VS-@@@24BE@) may be a similar
number of years as the maintenance forecast monitor according to
some settings. During operation over an extended period of time,
periodically check if the maintenance forecast monitor output (Yrs) or
total run time monitor output (kh) is correctly functioning by the
following procedure.
1. Select the operation mode.
2. Check that the output (Yrs/kh) is turned ON (with continuity).
3. In the operation mode, press and hold the Down Key D (10) and
the Mode Key M (8) simultaneously
for at least three seconds.
The main display (6) changes to “
a02.”
An inactive output (Yrs/kh) (no continuity) in the “
a02” indication
indicates the correct function.
4. Release keys to return to the regular state.
Note: DC output stays ON during the periodical check.
Overcurrent Protection
• Internal parts may possibly deteriorate or be damaged if a
short-circuited or overcurrent state continues during operation.
• Internal parts may possibly deteriorate or be 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.
• The DC ON indicator (green) flashes if the overload protection
function operates.
