Note
1. Power supply components may degrade, or
be damaged, when the power supply is
continuously used outside the shaded region,
refer to the graph shown in Fig. 1.
2. If the output capacity is not reduced when the
surrounding air temperature
exceeds its
specification as defined on Page 3 under
“Environment”, the device will run into Over
Temperature Protection. When activated, the
output voltage will go into bouncing mode and
will recover when the surrounding air
temperature is lowered or the load is reduced
as far as necessary to keep the device in
working condition.
3. In order for the device to function in the
manner intended, it is also necessary to keep
a safety distance as recommended in the
safety instructions while the device is in
operation.
4. Depending on the surrounding air temperature
and output load delivered by the power
supply, the device can be very hot!
5. If the device has to be mounted in any other
orientation, please contact [e-mail]
for more details.

Assembly & Installation
The power supply unit (PSU) can be mounted on 35 mm DIN rails in accordance with EN 60715. The device should be installed with
input terminal block at the bottom.
Each device is delivered ready to install.
1. Tilt the unit upwards and insert it onto the DIN rail. Snap on the DIN rail as shown in Fig. 3.1.
2. Push downwards until stopped.
3. Press against the bottom front side for locking.
4. Shake the unit slightly to ensure that it is secured.
5. To uninstall, pull or slide down the latch with screw driver as shown in Fig. 3.2. Then slide the power supply unit (PSU) in the opposite
direction, release the latch and pull out the power supply unit (PSU) from the rail.
Mounting Dismounting
Fig. 3.1 Mounting Fig. 3.2 Dismounting
In accordance to IEC/EN/UL/CSA 62368-1 and IEC/EN/UL/CSA 61010-2-201, flexible cables require ferrules.
Use appropriate copper cables designed to sustain operating temperature of:
•At least 75°C for ambient < 40°C
•At least 90°C for ambient < 70°C.

Safety Instructions
Vertical Mounting
•ALWAYS switch mains of input power OFF before connecting and disconnecting the input voltage to the unit. If mains are not turned
OFF, there is risk of explosion / severe damage.
•To guarantee sufficient convection cooling, please refer to the following instructions to ensure sufficient clearance around
the device.
Vertical Mounting: 80 mm (3.15 inch) above and 40 mm (1.57 inch) below the device as well as a lateral distance of 5 mm
(0.20 inch) to other units. In case the adjacent device is a heat source (50% load of 240 W), the lateral distance will be 25
mm (0.98 inch).
Horizontal Mounting: 80 mm (3.15 inch) above and 40 mm (1.57 inch) below the device as well as a lateral distance of 40 mm
(1.57 inch) to other units.
•The external enclosure where the unit will be installed shall meet the requirements for mechanical, electrical and fire enclosure.
•Note that the enclosure of the device can become very hot depending on the surrounding air temperature and load of the power
supply. Risk of burns!
•The main power must be turned off before connecting or disconnecting wires to the terminals.
•DO NOT insert any objects into the unit.
•Hazardous voltages may be present for up to 5 minutes after the input mains voltage is disconnected. Do not touch the unit during
this time.
•The power supplies are built in units and must be installed in a cabinet or room (condensation free environment and indoor location)
that is relatively free of conductive contaminants.
•The power supply is approved for the connection to 3-phase TN, TT and IT power grids (star networks) with a maximum phase-to-
phase voltage of 500 Vac.

Graph illustrating the Start-up Time, Rise Time, and Hold-up Time
Start-up Time
The time required for the output voltage to reach 90% of its final steady state set value, after the input voltage is applied.
Rise Time
The time required for the output voltage to change from 10% to 90% of its final steady state set value.
Hold-up Time
Time between the collapse of the AC input voltage, and the output falling to 95% of its steady state set value.
Inrush Current
Inrush current is the peak, instantaneous, input current measured
and, occurs when the input voltage is first applied. For AC input
voltages, the maximum peak value of inrush current will occur
during the first half cycle of the applied AC voltage. This peak value
decreases exponentially during subsequent cycles of AC voltage.
Dynamic Response
The power supply output voltage will remains within ±5% of its
steady state value, when subjected to a dynamic load from 0% to
100% of its rated current.

Overload & Overcurrent Protections (Auto-Recovery)
The power supply offers constant current limit protection for
inductive and capacitive load applications when output current
range is 105~150% of IO(Max load) and output voltage large than
80%. Upon such an occurrence, the VO(output voltage) will start
to droop. Once the power supply has reached its maximum power
limit, the protection will be activated; and, the power supply will
operate in continuous current. The power supply will recover once
the cause of OLP or OCP is removed, and IO(output current) is
back within the specified range.
Short Circuit Protection (Auto-Recovery)
The power supply’s output Short Circuit Protection function also
provides protection against short circuits. When a short circuit is
applied, the output current will operate in “Hiccup mode”. The
power supply will return to normal operation after the short circuit
is removed.
Overvoltage Protection (Auto-Recovery)
The power supply’s overvoltage circuit will be activated when its
internal feedback circuit fails. The output voltage shall not exceed
its specifications defined on Page 4 under “Protections”.
Over Temperature Protection (Auto-Recovery)
As described in load de-rating section, the power supply also has
Over Temperature Protection (OTP). In the event of a higher
operating temperature at 100% load, the power supply will run into
OTP when the operating temperature is beyond what is
recommended in the de-rating graph. When activated, the output
voltage will go into bouncing mode until the temperature drops to
its normal operating temperature as recommended in the de-rating
graph.
External Input Protection Device
The unit is protected with internal fuse at L1, L2 and L3 pins, with an internal fuse that cannot be replaced. The power supply has been
tested and approved on 20 A (UL) and 16 A (IEC) branch circuits without additional protection device. An external protection device is
only required if the supplying branch has an ampacity greater than above. Thus, if an external protective device is necessary, or, utilized,
please refer a minimum value in instruction sheet with 4 A B- or C- characteristic breaker.
