1. Terminal Explanation
Be sure to read this instruction manual thoroughly before using
this product. Pay attention to all cautions and warnings before
using this product. Incorrect usage could lead to an electrical
shock, damage to the unit or a fi re hazard.
DANGER
● Never use this product in locations where fl ammable gas or
ignitable substances are present
WARNING
● Do not touch this product or its internal components while it
is in operation, or shortly after shut down. There may be high
voltage or high temperature present and you may receive an
electric shock or burn.
● When the product is operating, keep your hands and face
away from it; an accident may injure you.
● Do not make unauthorised changes to this product, otherwise
you may receive an electric shock and void your warranty.
● Do not use this product in the event of the emission of smoke
or abnormal smell and sound etc. It might lead to fi re and/or
electric shock. In such cases, please contact us. Do not at-
tempt repair by yourself, as it is dangerous for the user.
● Do not operate these products in the presence of condensa-
tion. It might lead to fi re and/or electric shock.
● Do not drop or insert anything into the product. It might lead
to a failure, fi re and/or electric shock. Do not use the prod-
uct which dropped.
CAUTION
● This power supply is designed for use within an end product.
● Confirm connections to input/output terminals and signal
terminals are correct as indicated in the instruction manual
before switching on.
● Input voltage, Output current, Output power, ambient temper-
ature and ambient humidity should be kept within specifi ca-
tions, otherwise the product will be damaged.
● Do not operate and store this product in an environment
where condensation might occur. In such case, waterproof
treatment is necessary.
● Do not use this product in environment with a strong electro-
magnetic fi eld, corrosive gas or conductive substances.
● For applications which require very high reliability (Nuclear
related equipment, traffi c control equipment, etc.) it is neces-
sary to provide a fail safe mechanism in the end equipment.
● The information in this document is subject to change with-
out prior notice. Please refer to the latest version of the data
sheet, etc., for the most up-to date specifi cations of the prod-
uct.
● No part of this document may be copied or reproduced in any
form without prior written consent of TDK-Lambda.
● Do not inject abnormal voltages into the output or signal of
this product. The injection of reverse voltage or over voltage
exceeding nominal output voltage into the output or signal
terminals might cause damage to internal components.
● The output of this product is considered to be a hazardous
energy level (The voltage is 2V or more and the power is
240VA or more). It must not be made accessible to users.
Protection must be provided for Service Engineers against
indirect contact with the output terminals and/or to prevent
tools being dropped across them. While working on this prod-
uct, the AC input power must be switched off and the input
and output voltage should be zero.
● This product has a built-in fan for air-cooling. Do not block
the air intake and exhaust as this might lead to fi re.
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.
BEFORE USING THE POWER SUPPLY UNIT
① V.ADJ : Output voltage adjustment trimmer.
(The output voltage rises when a trimmer is turned clockwise.)
② ON : Output (Power On) indication LED.
(The indicator turns on when the power supply output is in normal operating
condition.)
③ CN1 : ON/OFF control signal, Current balance signal (only as for
HWS600P), Power fail signal. (Refer to 2-2.)
④ : Protective Earth terminal (Frame ground), M4 screw.
⑤ AC input terminal L : Live Line (Fuse in line), M4 screw.
⑥ AC input terminal N : Neutral line, M4 screw.
⑦ + : + Output terminal (HWS300P: M4 screw x 2 / HWS600P: M5 screw x 2)
⑧ - : - Output terminal (HWS300P: M4 screw x 2 / HWS600P: M5 screw x 2)
Please pay extra attention to the wiring. Incorrect connection will damage the power supply.
