Please pay extra attention to the wiring. Incorrect connection
will damage the power supply.
● When connecting input and output wiring, input AC-Line
should be off .
● Input wiring and output wiring shall be separated, otherwise
noise susceptibility of power supply unit will be weak.
● The protective earth (PE ) must be connected to the
instrument chassis and the chassis of this power supply unit.
● Remote sensing lines shall be twisted or use the shielded wire.
● Remote ON/OFF control lines shall be twisted or use the
shielded wire.

1. Terminal Explanation
Be sure to read the following precautions thoroughly before us-
ing this power supply unit.
Pay attention to all warnings and cautions before using the unit.
Incorrect usage could lead to an electric shock, damage to the
unit or a fi re hazard.
WARNING
● Do not make unauthorized changes to power supply unit,
otherwise you may have electric shock and void your warranty.
● Do not touch the internal components; they may have high
voltage or high temperature. You may get electric shock or
burned.
● When the unit is operating, keep your hands and face away
from it; an accident may injure you.
● Do not use unit under unusual condition such as emission of
smoke or abnormal smell and sound etc. It might cause fi re
and electric shock.
In such case, please contact us; do not repair by yourself, as
it is dangerous for the user.
● Do not drop or insert anything into unit. It might cause failure
and fi re, when using the unit under such condition.
● Do not operate these units at the condition of condensation.
It may cause fi re and electric shock.
● Power supplies with an output voltage of 48Vdc or less must
be earthed in the end use equipment to maintain SELV. If the
outputs are not earthed, they must be considered hazardous
and must not be made user accessible.
● Power supplies with an output voltage of 6 0Vdc are
considered to be non-SELV. As a result of this, the output
must be guarded or a defl ector fi tted during installation to avoid
a SERVICE ENGINEER making inadvertent contact with the
output terminals, or dropping a tool onto them. The output of
this product must not be connected to a SELV circuit.
Note : CE MARKING
● CE Marking when applied to a product covered by this
handbook indicates compliance with the low voltage directive
(2006/95/EC) in that it complies with EN60950-1.
CAUTION
● This power supply is primarily designed and manufactured to
use and enclose in other equipment.
● This power supply unit has a built-in fan for air-cooling. Do
not block air intake and exhaust. It might cause fi re.
● Input voltage, Output current, Output power, ambient
temperature and ambient humidity should be used within
specifi cations, otherwise the unit will be damaged.
● The unit might be broken down by accident or unexpected
situation. For application equipment, which requires very
high reliability (nuclear related equipment, traffic control
equipment, medical equipment, etc.), please provide fail
safety function in the equipment.
● Do not make an improper wiring to input and output
terminals. It may cause damage.
● Do not use in environment such as strong electromagnetic
fi eld, erosive gas etc, or any environment where conductive
foreign substance may enter.
● Do not operate and store this unit at the condition of
condensation. In such case, waterproof treatment is necessary.
● Do not operate this unit after it falls down.
● The output voltage of this power supply unit is considered
to be a hazardous energy level (The voltage is 2V or more
and the electric power is 240VA or more), prevention from
direct contact with voltage output is highly necessary. While
installing or servicing this power supply unit, avoid dropping
tools by mistake or direct contact with voltage output. This
might cause an electric shock.
While repairing this power supply unit, the AC input power
must be switch off and the I/O terminal voltage should be
less than the safety level.
