Engineering Data
De-rating
Assembly & Installation
The unit can be mounted on 35mm DIN rails in accordance with EN 60715. For Vertical Mounting, the device should be installed with
Input / Output terminal block on the bottom. For Horizontal Mounting, the device should be installed with Input / Output terminal block
on the left side.
Each device is delivered ready to install.
Mounting
Note
1. The unit may degrade, or be damaged, when
it is continuously used outside the shaded
region, refer to the graph shown in Fig. 2.
2. When the DC-UPS module is used with
power supply of different ratings, user must
follow power supply derating curve or
whichever is lower.
3. In order for the device to function in the
manner intended, it is also necessary to keep
a safety distance of 50mm above and below
the device as well as a lateral distance of
20mm (for Vertical Mounting) or 50mm (for
Horizontal Mounting)
with adjacent units
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 do not hesitate to contact
info@deltapsu.com f or more detai ls.
Fig. 2 No power de-rating across the entire operating temperature range
(-20°C to +60°C)
Dismounting
Fig. 3.1 Mounting
Snap on the DIN rail as shown in Fig. 3.1:
1. Tilt the unit upwards and insert it onto the DIN rail.
2. Push downwards until stopped.
3. Press against the bottom fr ont side for lockin g.
4. Shake the unit slightly to ensure that it is secured.
Fig. 3.2 Dismounting
To uninstall, pull or slide down the latch with screw driver as
shown in Fig. 3.2. Then slide the unit in the oppos ite dire ctio n,
release the latch and pull out the unit from the rail.

Safety Instruc ti ons
Vertical Mounting
– When replacing batteries, only use the same type of batteries listed under the “Battery Input / Output Characteristics” section on
Page 2.
– Proper disposal of batteries is required. Refer to the relevant local codes for disposal requirements.
– 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.
– If the orange status LED is on, this indicates a failure in the installation. In this case, do not turn on power supply while the battery
is connected. Danger of explosion!
– To guarantee sufficient convection cooling, keep a distance of 50mm above and below the device as well as a lateral
distance of 20mm (for Vertical Mounting) or 50mm (for Horizontal Mounting) to other units.
– 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 t o 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 unit is a built-in unit and must be installed in a cabinet or room (condensation free environment and indoor location) that is
relatively free of conductive contaminants.

Overload & Overc ur rent Protecti ons
When the output current exceeds the maximum specified output
current. The DC-UPS module will shut down and protect itself.
Normal operation of the module can be resumed upon removal of
fault.
Short Circuit Protection
The module is protected in case of short circuit at customer
system, in the event of short circuit the module will shut down and
protect itself. Normal operation can be resumed upon removal of
fault.
Overvoltage Protection
The DC-UPS module’s overvoltage protection will be activated
when DC input to the module exceeds the maximum specified
input voltage. The unit shall shutdown and return to normal state
when the OVP condition is removed.
Over Temperature Protection
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 shut down and remain in off
state until the temperature drops to its normal operating
temperature as recommended in the de-rating graph.

Delta RoHS Compliant
Restriction of the usage of hazardous substances
The European directive 2011/65/EU limits the maximum impurity level of homogeneous materials such as lead,
mercury, cadmium, chrome, polybrominated flame retardants PBB and PBDE for the use in electrical and
electronic equipment. RoHS is the abbreviation for “Restriction of the use of certain hazardous substances in
electrical and ele ctr on ic equ ip ment”.
This product conforms to this standard.
Conformal Coating
The Protective Coating Technology
Delta Electronics Group has designed the perfect dipping technique which penetrates everywhere including
under device, and prevents leakage. The conformal coating dipping can be applied to PCBs or circuit board.
The coating preserves the performance of precision electronic primarily by preventing ionizable contaminants
such as salt from reaching circuit nodes, where the material slumps around sharp edges. This can be a problem
especially in highly conversing atmosphere.
