Enclosures

Mounting - wall mounting

  • The products shall be mounted on a stable wall or mounting plate with sufficient bearing capacity for the weight of the enclosure, including batteries.

  • The enclosure is mounted vertically.

  • Use four screws with a diameter of 4—5 mm, depending on the substrate.

  • Recommended distance between screw head and wall should be 1.5-2 mm.

  • For mounting on drywall, wall anchors or expanders should be used.

  • When mounting on concrete or brick, dowels or equivalent fastening are used.

  • For good ventilation, at least 100 mm of free space should be provided above and on the sides of the enclosure.

  • The unit should be mounted at a comfortable working height, normally between 1.4 and 1.8 m above the floor.

  • Avoid placement in direct sunlight, near heat sources, or in environments with high humidity or dust.

  • For outdoor use, only enclosures with the specified IP class for outdoor use shall be used.

  • Installation shall be carried out in accordance with the applicable installation rules and by a competent installer.

Wall mounting

Use four screws suitable for the wall to mount the cabinet.

The distance between the screw head and the wall should be 1.5–2 mm.

Preferably leave a 100 mm air gap around the unit.

Batteries - placement and connection

Connection of battery ECO S 12 V

Caution

Check battery voltage when switching on. Before installation, the voltage of each individual battery must be measured. Never connect two batteries whose 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.

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.

Caution

Check battery voltage when switching on. Before installation, the voltage of each individual battery must be measured. Never connect two batteries whose 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

  1. Slide batteries from the side with the battery terminals toward the center. Only use new batteries during installation and battery replacement.

  2. Connect fuses on batteries. Connect red cable to + (plus) and black cable to - (minus)

  3. 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 nameplate 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

Secure F and N with cable ties.

Important

Mains wiring must be kept separate from other wiring to avoid EMC interference.

Important

protective earth (PE) should 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

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.

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 its

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.
