General assembly instructions
Mounting - wall mounting
Enclosure must be mounted vertically.
For good ventilation, at least 100 mm of free space should be provided above and on the sides of the enclosure. Do not block the flow of air on the sides
The device should be mounted at a comfortable working height, normally between 1.4 and 1.8 m.
Recommended distance between screw head and wall should be 1.5-2 mm.
Avoid placement in direct sunlight, near heat sources, or in environments with high humidity or dust.
Installation shall be carried out in accordance with the applicable installation rules and by a competent installer.
Batteries - placement and connection
Connection of battery ECO S 12 V
Caution
Check battery voltage before switching on. Before installation, the voltage of each individual battery must be measured. Never connect two batteries if their terminal voltage differs by more than 0.3 V (max 0.4 V). Too large a voltage difference may indicate a damaged battery and lead to performance degradation, battery damage or overheating with the risk of fire.
Left ECO 12V with 1 battery. Right ECO 12 V with two batteries.
12 V with a battery: Battery cables from motherboard are connected to battery plus and minus pole. Battery fuse is on circuit board.
12 V with two batteries: Battery cables from motherboard are connected to battery plus and minus pole of each battery. Fuses must be connected to each battery pole. A fuse on minus poles and a fuse on plus poles.
Note
Fuses that come with the device in a bag should not be used when using 1 battery.
Connection of batteries, 24V
Caution
Check battery voltage before switching on. Before installation, the voltage of each individual battery must be measured. Never connect two batteries if their terminal voltage differs by more than 0.3 V (max 0.4 V). Too large a voltage difference may indicate a damaged battery and lead to performance degradation, battery damage or overheating with the risk of fire.
Mains voltage should be disconnected when connecting batteries
Slide the batteries in from the side with the terminals facing each other (toward the center). Only use new batteries during installation and battery replacement.
Connect fuses on batteries. Connect red cable to + (plus) and black cable to - (minus)
Connect cables from battery backup to batteries. Connect red cable to + (plus) and black cable to - (minus)

Max current
The maximum current must not be exceeded. Max current is indicated on the rating plate on the device.
Danger
Mains voltage must be disconnected when working with stripped cables. It is the installer's responsibility to ensure that the correct skills are available for connecting 230 V to the unit. Maximum cable area is 4 mm2
Connect mains
Before connecting, the supply circuit should be disconnected and voltage-free. Verify that the conductor area and cable type meet the applicable installation rules and that the strain relief and insulation levels comply with the requirements for 230 V AC
After connection, all screw connections should be checked and tightened. Tensioning shall only take place after mechanical protection, caps and housing have been reassembled and comply with the contact protection according to EN 62368-1
Secure F and N with cable ties.
Important
Protective earth (PE) must be connected to the PE terminal on the motherboard. The motherboard is grounded via its mounting points in the enclosure, ensuring proper potential equalization between PCB and enclosure. Also the cover is grounded through ground cable/earth braid between cover and enclosure to maintain continuity and EMC
Mains wiring must be kept separate from other wiring to avoid EMC interference.
The protective earth (PE) must be connected to the PE terminal on the motherboard. The motherboard is grounded via its mounting points in the enclosure, ensuring correct equipotential bonding between the circuit board and the enclosure. The cover is also grounded via a grounding cable / grounding braid between the cover and the enclosure to maintain continuity and EMC function.
Check that the marking on the circuit board matches the wiring order on the terminal block.
Connect the mains cable to the terminal block before it is re-inserted into the motherboard. Secure L (F in picture) and N with cable ties for electrical safety.

All units | F7 | T16A | Battery fuse |
Warning for replacing fuses (current strength, A)
There is a risk of damage if the fuse is changed to a larger one than what the unit is delivered with. The function of the fuse is to protect the connected load and cables against damage and fire. It is not possible to change the fuse to a larger one to increase the power output.
Alarm displayed on cabinet door
In normal mode, the indicator LED shows a solid green light.

About
The ECO series are reliable and small battery backups for use with access systems, locking systems and other loads. The battery backups have controlled charging* which prevents batteries from overcharging, which significantly prolongs their service life.
Areas of use
Most used in:
Alarm
The device alarms for:
Undervoltage/low battery voltage.
Fixed installation
The product is intended for fixed installation. The battery backup must be installed by a qualified installer.
Test before installation of 230 V
"Cold start" means that the battery backup can be commissioned with only the batteries connected without the battery backup being connected to 230 V. This is practical if the installer is not a qualified electrician but still wants to be able to test the system.
