INTIEL Uninterruptable Power Supply for Circulation Pumps
Application
Gas boilers for heating and domestic hot water preparation are very popular as they are being used for residential and commercial applications, as well as for heating systems with boilers, etc. for water circulation using circulation pumps. One of the main disadvantages of such systems is their dependence of the electrical power supply. Therefore, the prevention of electrical cut-off is very important for these systems as it is able to be provided only by means of using an uninterruptable power supply. The present device is able to provide the necessary power supply backup to run the gas boilers for quite a long period of time.
Operation
The backup power supply is provided by means of switching between the grid ~220V / 50 Hz and the backup power provided by a 12V battery (which in fact is an external energy source for the device).
The switching is being provided automatically in relation to the power supply grid presence.
Presence of a grid power supply
This mode is indicated by the green indicator “Main supply”
The unit is being power supplied by means of the grid as within that time the device operates as a battery charger. The battery voltage is observed automatically as when a voltage of 13,8 – 14,2 V is reached then the charging is stopped. The device periodically charges the battery due to the self- discharging process during the time when a power supply grid is available. In this way battery maintenance is not necessary, providing constant keeping of the battery in standby mode for subsequent usage in case of power supply cut- off.
The battery status is indicated on the LED scale from 25 to 100%
Absence of a grid power supply
This mode is indicated by the indicator “Load”
In this case, the gas boiler or the pump is being power supplied by the battery by means of a DC/AC inverter 12V / 220V. The battery voltage is being observed as if it is being decreased a sound signal appears at 10,6V, and at 10.3V red light indication “Failure” appears, and the power supply of the unit is stopped until the grid is restored. It means the battery is exhausted and its subsequent usage is possible only after recharging.
The device is able to work with a 12V internal battery with a capacity of 7.5Ah or an external 12V car battery with a capacity of up to 100Ah.
Should be known that Uninterruptable Power Supply can not work without any
battery.
It is desirable before installing the battery to check the status and if the
battery voltage is below 10V it must be charged this can be done after the
installation of the battery by inserting the plug of the Uninterruptable Power
Supply the mains power supply and the ON / OFF button is in the OFF position
and wait until the battery is sufficiently charged. The internal battery is
able to provide a backup power supply of up to one hour if the unit electrical
consumption is up to 50W, as if the previously mentioned consumption is bigger
it is recommended the usage of external battery.
For example, if the gas boiler or the pump consumption is 150W and the battery capacity is 100Ah, the device is to provide a backup power supply up to 10-12 hours.
Protections
- Overload protection and short circuit at the output – this protection act immediately and prevents damage to the device under overload or short circuit at the output when activated following dropping the output voltage and the Load indicator goes off and the Failure indicator lights up. Protection is automatically restored after the removal of the overload or short circuit.
- Protection from the wrong connection of the battery.
- Protection of the defect in the device is realized by a fuse inside the device.

Installation
Follow the instructions below in order to provide proper installation of the device.
- Fix the metal plate on the wall, where the device is to be placed (see fig.1)
- Hang up the device of the metal plate.
- If the device is to work with an internal battery, it is to be connected observing its polarity (see Fig.2)
- Remove the top cover of the device by unscrewing the lateral four bolts.
- Insert the battery into the battery compartment (position 1)
- Install an appropriate instrument cable shoes to the wires.
- Connect the wires observing the battery polarity, the red wire is to be connected to plus terminal / + / and the black one to the minus terminal.
- Connect plug B to A connector according to Fig. 4 and mount the cover of this device by screwing four screws.
- If the device is to work with an external battery, the cable compartment cover is to be removed according to Fig. 3.
- Remove the top cover of the device by unscrewing the lateral four bolts.
- Thread the battery wires through the hole in the box pos.2
- fix the battery terminals by observing their polarity. The one marked with plus / + / is to be connected to the red cable, as the one marked with minus to the black cable.
- Connect the plug B to A connector according to Fig. 4 and mount the cover of this device by screwing four screws.
- Plug in the gas boiler or pump into the outlet of the Uninterruptable Power Supply.
- Plug in the Uninterruptable Power Supply into the power supply grid.
- The Uninterruptable Power Supply is to be switched on by pressing the button ON/OFF into position ON, as a light indication “Main supply” appears. Then the device is to be powered by the grid.
- Make a switch-off test of the grid, unplugging the device. light indication “Load” must so remain lit and the unit will be powered by the device.
- Plug in the device again into the grid.
In carrying out activities on including power unit or battery change to be
made after placing the ON / OFF button in position OFF.
**DEFECTS
**
The process of installation and operation can occur the following the failure
| Defect | Possible reason | Removal of the fault |
|---|
The device work in mode AC Power and does not work in the absence of mains power and STATUS BATTERY indicator lights 25%| – Exhausted Battery
– Bad connection to the battery terminals
| – Place the ON / OFF button set to OFF and wait to charge the battery
– Check the battery status
– Check battery terminals for
the presence of a bad connection
In the presence of mains power the device does not
work
| Burnt fuse F1/2A /| To check and replace the fuse F1 / 2A /
Output voltage is absent / does not light up the indicator Load|
Activated protection against overload and short circuit in the output| To
disconnect the unit from the outlet of backup power if the indicator Load
light have to check for the presence of a
short circuit in power unit
For all other cases of failure| | Contact an authorized service
The removal of the all the above faults to be made after placing the button in the OFF position and pulling the plug from the mains socket.
