Safety Class of Protection
The unit is designed for the following parameters: Material Group IIIb, Pollution Degree 2, Overvoltage Category II, Class
1 (earthed), Indoor use. The unit is considered as fixed and rated IPX0. The TPS400024 and TPS400048 are classed as
having SELV outputs. All outputs are capable of providing hazardous energy (>240VA). The final equipment should
provide protection to service personnel against inadvertent contact with the PSU output terminals.
Installation
This product is designed for use within other equipment which restricts access to Authorized competent personnel only.
The unit covers/chassis must not be made user accessible.
The appliance may be mounted in any orientation.
The mains input connector is not acceptable for use as field wiring terminals.
The appliance must be securely mounted and the baseplate properly bonded to the main protective earth contact before
any connection to AC mains supply is made.
The ventilation openings must not be impeded – ensure a space at least 5cm between any obstruction and the ventilation
openings.
BEFORE USING THE POWER SUPPLY UNIT
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 fire hazard.
DANGER
 Never use this product in locations where flammable gas or ignitable substances are present.
WARNING
 Do not make unauthorized changes to power supply unit, otherwise you might have electric shock and void your
warranty.
 Do not touch this unit and the internal components in operation or shortly after shut down. They might have high
voltage or high temperature and as the unit dissipates its heat so the surface of the unit is hot. You might receive electric
shock or burn.
 When the unit is operating, keep your hands and face away from it; you might be injured by an accident.
 Do not use unit under unusual conditions such as emission of smoke or abnormal smell and sound etc. It might cause
fire 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 fire.
 Do not operate these units under condensation condition. It might cause fire and electric shock.

CAUTION
 As a component part, compliance with the standard will be based upon installation in the final application. This product
must be installed in a restricted access location, accessible to authorized competent personnel only. These AC to DC
converters have reinforced insulation between the input and the output. The outputs of these products are energy hazards.
The equipment has been evaluated for use in a Pollution Degree 2 environment.
 This product is designed for use within other equipment or enclosures which restrict access to authorized competent
personnel only and must not be user accessible. Confirm connections to input/output terminals and signal terminals are
correct as indicated in the instruction manual.
 Input voltage, Output current, Output power, ambient temperature and ambient humidity should be used within
specifications, otherwise the unit will be damaged.
 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 use the product in environment with strong electromagnetic field, corrosive gas and conductive substance.
 Do not operate and store this unit at an environment where condensation occurs. In such case, waterproof treatment is
necessary
 Never operate the unit under over current or shorted conditions for 30 seconds or more and out of Input Voltage Range
as specification. Insulation failure, smoking, burning or other damage might occur to the unit.
 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 output terminal is highly necessary. While
installing or servicing this power supply unit, avoid dropping tools by mistake or direct contact with output terminal. This
might cause an electrical shock. While repairing this power supply unit, the AC input power must be switched off and the
input and output voltage should be level.
 To maintain the SELV output, under fault conditions, the output must be connected to earth in the final application.
 The application circuits and their parameter are for reference only. Be sure to verify effectiveness of application
circuits and their parameters before finalizing circuit design.
 Do not inject abnormal voltage to output terminal and signal terminal from the outside. The injection of reverse voltage
or over voltage exceeding nominal output voltage to output terminals might cause damage to internal components.
 This information in this document is subject to change without prior notice. For actual design-in, please refer to the
latest publications of data sheet, etc., for the most up-to date specifications of the unit.
Note: CE MARKING
CE Marking when applied to a product covered by this handbook indicates compliance with the low voltage directive (2014/35/EU) in that it
complies with EN/IEC 60950-1.
