General assembly instructions
Indoor mounting in 19" rack
The product should be mounted in a standardized 19" rack or cabinet with sufficient carrying capacity for the weight of the enclosure including batteries.
The device should be mounted at a comfortable working height, normally between 1.4 and 1.8 m.
The device is mounted horizontally in the rack with the included rack ears or corresponding brackets.
Check that the rack posts are properly aligned and that the spacing corresponds to the 19" standard (465—470 mm between the inner edge of the posts).
When assembling, cage nuts or locking washers should be used to ensure that the screws fit securely.
For good ventilation, at least 100 mm of free space should be provided above and below the unit. Do not block the air flow on the front or back.
Batteries should always be placed as directed and must not block ventilation openings or wiring.
Installation shall be carried out in accordance with the applicable installation rules and by a competent installer.
Mounting
Use the appropriate screw for mounting on a wall or in a 19" rack. Screws for mounting on a wall or in a rack are not included.
For wall mounting in concrete, concrete screws must be used. For rack mounting, M6 with basket nut is used
Screw length should be adjusted according to wall material and load. The specified screw length is the minimum allowable length
Mounting holes, spacing and ø.

Mounting the 19" rack box
Check that the cover is fastened with the supplied nuts.
Place the box in the desired position in the 19" rack.
Screw the box on both sides into the rack profile with screws designed for 19" racks.
Warning
Do not insert the batteries until the rack box is properly assembled and securely attached to the rack. The weight of the batteries can make the box unstable if it is not properly bolted

Plug 230 V out
Connect cargo to the outlet on the back of the box. The socket is supplied with backup power and can be energized during battery operation
Connection of supply voltage, 230 V AC
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
Important

Safety Information - Service and Troubleshooting, UPS
Disconnect the incoming mains voltage before starting service, battery replacement, measurement or troubleshooting.
Note that the output of the UPS may be energized even when the incoming mains voltage is disconnected. Disconnect connected load and control meter 230 V AC out before starting work.
Remove battery fuse, disconnect battery connector, or turn off automatic fuse before work is performed on the DC side.
Check that the incoming 230 V AC, output 230 V AC, protective ground and battery connections are properly connected before re-energizing the unit.
The product may contain components that become hot during operation. Avoid touching internal parts immediately after power is broken.
If fuses fail repeatedly, disconnect the unit and contact Milleteknik technical support.
In case of suspicion of damage, liquid effects or burnt odour, the product must not be used until it has been checked by competent personnel.
During operation, the housing should be closed and locked, if the device has a lock.
Only authorized service personnel may perform repairs on the device.
Use only original fuses and batteries of the same type and value as specified in the manual or product sheet.
Trouble | Possible cause | Action |
|---|---|---|
No voltage out from the UPS. | Incoming mains voltage is missing, batteries are discharged, battery fuse is missing or load output is disconnected. | Check incoming feed, battery connections, battery fuse and connected load. |
UPS is switching to battery operation. | Incoming mains voltage is missing or is outside the permissible range. | Check the incoming 230 V AC and fuse in the supply circuit. |
Load does not work in case of network outage. | Batteries are discharged, disconnected, miswired or have too low capacity. | Check battery voltage, polarity, battery fuse and battery condition. |
Short backup operation time. | Batteries are not fully charged, aged or the load is higher than estimated. | Allow the batteries to recharge. It can take up to 72 hours for the batteries to be fully charged. Check the load and the condition of the batteries |
Fuse dissolves. | Short circuit, overload, mismatched load or battery cable failure. | Break the incoming mains voltage and check both AC and DC side before replacing the fuse. |
UPS alarms. | Battery failure, overload, mains failure, temperature failure or internal failure depending on the model. | Check the indication, panel or manual for the current alarm declaration. |
The device gets hot. | High load, insufficient ventilation or too high ambient temperature. | Check that the rated current is not exceeded and that air flow is present around the housing. |
If the problem persists after these checks, contact Milleteknik support and provide the product name, serial number and a brief error description.

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/
