Product description
Switch mode power supply units (PSU) UP412 and UP413 are intended to supply devices, required increased reliability
of supply voltage for back-up function implementation. Enable work of 2 or more PSU UP412 and UP413 in parallel
connection in any combinations.
UP413 does not have possibility of monitoring.
UP412 is TERRA BUS+ protocol supported device. It is possible to get information about output voltage, temperature
and output current via TERRA BUS+ protocol.
The units are intended for indoor use only.
Safety instructions
The PSU is powered from the mains 230 V~. This voltage is dangerous to life.
Any repairs must be done by a qualied personnel.
PSU is double isolated from the mains 230 V~.
Do not remove the cover without disconnecting PSU from the mains.
Do not plug the PSU into the mains supply if the power cord or plug is damaged.
To disconnect the PSU from the mains completely, disconnect plug from the mains socket.
The mains socket must be easily accessible.
PSU shall not be exposed to dripping or splashing water and no objects lled with liquids, such as vases, shall be
placed on it.
Avoid placing PSU next to central heating components and in areas of high humidity.
No naked ame sources, such as lighted candles, should be placed on PSU.
If the PSU has been kept in cold conditions for a long time, keep it in a warm room no less than 2 hours before plugging
into the mains.
The ventilation should not be impeded by covering the ventilation openings with items, such as newspapers,
table-cloths, curtains.
Mount the PSU in vertical position.
From top, front and bottom of installed PSU must be at least 10 cm free space.

Installation
When outputs of UP412 and/or UP413 are working in parallel it is recommended to connect PS units to different lines
of the mains or one to the line directly, another via uninterruptable power source (UPS). Disconnected from the mains one
PSU does not disturb parallel working PSU.
Warning!
• Maximal output current of parallel connected PS units can not exeed output current of one PSU.
• Connecting or disconnecting powering of modules must be done when PSU is disconnected from the mains.
• Each device in system connected to the same control bus must have different address.
• Connect in parallel PS units, intended to work in parallel only: UP412+UP412, UP412+UP413, UP413+UP413 (see
gure 6).
• Connection of other model of PSU in parallel with UP412 and/or UP413 is not allowed.
Setting of address
PSU UP412 has possibility to set 64 different addresses – 4 groups, 16 units in each group. To change number of
module number of group not need to disconnect device from the mains.
Example. Need to set module No2 in group No1. To set group No1, group switches turn up. To set module No2, turn
rotary switch to position 2. Now software via TERRA BUS+ protocol will appear UP412 at address 2.
MOUNTING
The module or mounting bracket must be xed with steel screws Ø 3.5-4 mm. The screws are not included in a package.
