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.
Connect the mains to the motherboard (PCB)
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.

Filter Capacitors
The products are supplied with the following filter capacitors for standard networks (TN/TT):
Type | Location |
|---|---|
X2 | Phase — Zero (L—N) |
Y2 | Phase/Zero — Protective ground (one per conductor) |
IT Networking
IT networks generate higher transients as the system works phase to phase. Therefore, according to the current standard, capacitors of a higher class are required
Departure from X1/Y1 capacitors can be done but then external transient protection must be installed. For devices to be installed in IT networks, Milleteknik's lightning protection must be fitted to maintain standards.
Connect load
Max current
The maximum current must not be exceeded. Max current is indicated on the rating plate on the device.
If there are one or more connection cards (to increase the number of load outputs), load must be connected there and not on the main board.
On circuit boards | Explanation |
|---|---|
P2: 1 | Connection for load 1 +. |
P2: 2 | Hookup for load 1 -. |
P2: 3 | Connection for load 2 + |
P2: 4 | Connection for load 2 - |
Caution
Load may only be connected to the motherboard in 5 A and 10 A units. For other units, load must be connected via power board or option board.
Connection of load 15 A - 25 A units
For units with a effect card, which is available to handle the higher currents (15 ampere and above), the load must be connected on an optional board.
See documentation for option board for how to connect load.
Warning
Load must not be connected to the motherboard if the device is a 15 A or 25 A, as it will be destroyed during commissioning. Motherboards that are faulty due to incorrect connections are not covered by warranty.

The effect card increases the current for 15 A and 25 A units.
Dip switch 1-8
Dip-Switch has several different modes:
Dip switch | In mains operation or in battery operation |
|---|---|
1 | Address for external communication. |
2 | Address for external communication |
3 | Address for external communication |
4 | Address for external communication |
5 | Sets alarm for mains failure delay |
6 | Sets alarm for mains failure delay |
7 | Sets alarm limit for low battery voltage in battery operation. |
8 | Turns off or turns on LED indication, for everything except alarm in case of triggered tamper contact which is always indicated regardless of dip-switch position. |
8 in sequence | Perform battery tests. |
Mains failure delay (dip 5-6)
It is possible to change the time for when the alarm for a power outage should be given. Use the matrix to set the alarm.
Alarms for mains failure are given after: | Dip 5 | Dip 6 |
|---|---|---|
3 seconds | OFF | OFF |
30 minutes | ON | OFF |
60 minutes | OFF | ON |
240 minutes (4 hours) | ON | ON |
Low battery voltage (dip 7)
Dip: 7 has the same function regardless of whether the unit is in mains or battery operation or whether the tamper switch is held down.
Alarm for low battery voltage is given when | Dip 7 |
|---|---|
22,8 V* | ON |
24 V | OFF |
*25% of battery capacity remains. | |
LED (dip 8)
LED/battery-test always lights up when the door is open.
Dip-switch 8=ON turns off the LED.
Dip-switch 8=OFF turns on the LED.
Battery test (dip 8)
To do a battery test, dip 8 needs to change position and five seconds need to pass before the test is initiated.
If dip 8 in original position is on OFF then switch dip 8 to: ON (wait 5 seconds) and then switch back to OFF.
If dip 8 in original position is on ON then switch dip 8 to: OFF (wait 5 seconds) and then switch back to ON.
This activates the battery test after 3-8 seconds. The battery test lasts for about 6 seconds and then the LED flashes yellow quickly. Aged battery alarms may be indicated while the battery test is being performed.
Only reset dip 8 when the test is complete.
Reboot to confirm changes in address, battery and alarm settings to parent system
After the dip-switch has been set for various parameters, the device's software needs to be restarted. This is for the new settings to be stored and take effect.
Important
Rebooting according to this procedure does not interrupt the output voltage.
Restarting the device software is done by jumpering J13 (PRO2)
Important
Reboot must be done every time a change is made to the device.
NEO cannot be connected to communication/UC.
Alarm card for PRO2
Relay card - description, connections and alarm outputs.
All fault arm relays must be in the drawn state. Check that there is a gap between CO and NC. Put the measuring instrument on continuity measurement and test closure. This should then indicate a short circuit.
All relay outputs are normally live and give an alarm in the event of no voltage.
Important
There is normally a 10 second delay in alarm reset. The software on the main board must be configured for a different time period.

Appendix
Backup operating time on batteries
The reserve operating time in battery operation depends on how large a load is connected to the power supply. If the load varies, as with frequent opening of door locks, the time that batteries can continue to power the security system decreases. To get an estimate of reserve operating times see: www.milleteknik.se/Manualer/FaQ/Reservdrifttider/
