HWS 1000 Series Instruction Manual
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, oth-
erwise you may have electric shock and void your warranty.
● Do not touch the internal components; they may have high volt-
age 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 60Vdc are con-
sidered 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 hand-
book 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 tempera-
ture and ambient humidity should be used within specifi ca-
tions, 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 equip-
ment, 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 conden-
sation. 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 install-
ing or servicing this power supply unit, avoid dropping tools
by mistake or direct contact with voltage output. This might
cause an electrical 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.
CAUTION of IEC/EN/UL60601-1 for HWS1000/ME
CAUTION
●These products are designed for continuous operation within an
overall enclosure, and must be mounted such that access to the
mains terminals is restricted. See Clause 16, IEC/EN/UL60601-1.
●These products are NOT suitable for use in the presence of
flammable anaesthetic mixtures with air or with oxygen or
with nitrous oxide.
●Connect only apparatus complying with IEC/EN/UL60601-1
to the signal ports.
●Except for permanently installed equipment as defined in
Clause 57.6 of IEC/EN/UL60601-1 the overall equipment
in which these products are installed must have double pole
fusing on the input mains supply. The products themselves
have single pole fusing in the live line.
●These products provide basic insulation only between mains
and output, with reference to IEC/EN/UL60601-1.Sure to add
supplemental insulation to input or output in the equipment.
●Reference should be made to local regulations concerning the
disposal of these products at the end of their useful life.
●The maximum normal leakage current of this product is 500
microamperes for IEC/EN/UL60601-1. When using it as a
patient care equipment, all outer surfaces of the equipment
shall be constructed of nonconductive material. See Clause
19.5DV.2 of UL60601-1.
●These products have not been assessed to IEC/EN60601-1-2
(EMC) but EMC test data is available from TDK-Lambda.
BEFORE USING THE POWER SUPPLY UNIT
Please pay extra attention to the wiring. Incorrect connec-
tion 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 instru-
ment 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.
