Precautions for Safe Use
Mounting
Ensure sufficient heat dissipation when installing the Power Supply
to increase its long-term reliability.
Use the metal plate as the mounting panel.
When cutting out holes for mounting, make sure that cuttings do not
enter the interior of the Power Supply.
When mounting two or more Power Supplies side-by-side, allow at
least 20 mm spacing between them, as shown in the illustrations
below.
15/30/50/100/150-W Models
Natural cooling is used, so mount the Power Supply so that there is
airflow around it.
Improper mounting will interfere with heat dissipation and may occa-
sionally result in deterioration or damage of internal parts. Use the
Power Supply within the derating curve for the mounting direction
that is used.
The internal parts may possibly be damaged if mounting screws are
over inserted. Refer to Dimensions on page 19 to 21 for maximum
depth of insertion inside the Power Supply.
Several Power Supplies cannot be connected. (Only S8VM-

) Keep the Power Supply as far away from
heating elements as possible when installing. As a reference value,
allow at least 50 mm spacing on the right and left sides. If only 20
mm spacing is allowed, use the Power Supply at a load ratio of 80%
or less.
300/600/1,500-W Models
A forced-air cooling method with a fan is used. To ensure sufficient
cooling, do not cover the air holes located on the side the fan is
mounted and the opposite side.
Improper mounting will interfere with heat dissipation and may occa-
sionally result in deterioration or damage of internal parts. Do not
use the Power Supply in any mounting direction other than those
specified.
The internal parts may possibly be damaged if mounting screws are
over inserted. The screws must not protrude more than 6 mm inside
the Power Supply.

5. Use a metal plate as the mounting panel.
Wiring
Connect the ground completely. A protective earthing connection
stipulated in safety standards is used. Electric shock or malfunction
may occur if the ground is not connected completely.
Minor fire may possibly occur. Ensure that input and output terminals
are wired correctly.
Do not apply more than 100 N force to the terminal block when
tightening it.
Be sure to remove the sheet covering the Power Supply for
machining before power-ON so that it does not interfere with heat
dissipation.
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.
Minor electric shock, fire, or Product failure may
occasionally occur. Do not disassemble, modify, or repair
the Product or touch the interior of the Product.
Minor burns may occasionally occur. Do not touch the
Product while power is being supplied or immediately
after power is turned OFF.
Fire may occasionally occur. Tighten terminal screws to
the specified torque.
15-, 30-, 50-, 100-, and 150-W models (1.6 N·m)
300-, 600-, and 1,500-W models (M4; 1.27 N·m, M5; 2.50
N·m, M8 bolts and nuts; 10.8 N·m)
Minor injury due to electric shock may occasionally occur.
Do not touch the terminals while power is being supplied.
Minor electric shock, fire, or Product failure may
occasionally occur. Do not allow any pieces of metal or
conductors or any clippings or cuttings resulting from
installation work to enter the Product.
