Electronics, regardless of enclosure, are intended for use in a controlled indoor environment. Mains voltage should be disconnected during installation.

It is the installer's responsibility that the system is suitable for its intended use. Only authorized persons should install and maintain the system.

All information subject to change.

About glass tube fuses on certified devices

There are glass tube fuses on the circuit board's load outputs, these have a tripping time of approx. 150 ms. In the event that a glass tube fuse trips on ONE load output, the voltage on ALL load outputs drops to 0 V for 150 ms.

The installer is responsible for ensuring that there is an energy buffer of at least 150 ms in systems that the battery backup supplies power to or accepts a power failure of 150 ms.

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 J11 (PRO3)

Important

Reboot must be done every time a change is made to the device.

NEO cannot be connected to communication/UC.

Reset after battery replacement -PRO3

After battery replacement, the device needs to measure the capacity of new batteries and clear previously set battery capacity. All alarms are cleared from the units memory, statistics remains and can not be cleared.

  • Insert jumper on J11 and remove jumper on J11

After doing step, the battery capacity is cleared in the units memory and is ready to read the new battery capacity.

This procedure needs to be done each time the batteries are replaced or when connecting a battery box.

Note on test of batteries

At start-up, it takes 72 hours before the system performs battery tests. This is to ensure fully charged batteries and to collect averages / history for at least 72 hours. Thereafter, every four hours, a qualified cell sample of the batteries is performed.

Note on start-up with short-circuited batteries

Peak current at start-up with short-circuited batteries: Up to 30 A p-p for 200 ms. Always follow the start-up procedure.

Notice

If the indicator light flashes every 15 seconds, the battery is fully charged and the charge is in rest phase to extend battery life. In the event of a power failure during the rest phase, the battery backup switches to battery operation as usual

Adjustment of tamper switch

SABK_PLIERS_INSTRUCTION.eps

The tamper switch lever must be in the closed position when the cabinet door is closed. If the alarm goes off ("tamper alarm"), the lever may needs to be adjusted.

The lever is adjusted by the following steps:

  1. Pinch with pliers in the middle of the lever.

  2. Carefully adjust the lever in the desired direction (up / down).

  3. Check by closing the door. A click is heard when the contact is closed.

Notice

Tamper switch will not give an alarm when closed and locked the door.

Maintenance

The system with the exception of batteries is maintenance-free when installed in an indoor environment.

Check the fan annually. The fan should rotate smoothly without any noise. Clean the fan from dust and dirt. The fan must be replaced if it does not rotate smoothly or is so dirty that it cannot be completely cleaned. If the fan does not work well, the air flow in the unit will be obstructed, which leads to an increase in heat in the enclosure, which can lead to a deterioration of the battery capacity and to a significantly shorter battery replacement interval.

About batteries

Batteries generate electricity through a chemical process and there is thus a natural degradation of capacity. The biggest factor in battery life is temperature. The higher the temperature, the shorter the battery life. The date of manufacture stamped on the battery and the service life (as stated by the battery manufacturer). An ideal temperature is 20 °C both in operation and in storage. Higher ambient temperature greatly reduces the service life. Thus, actual lifespan varies when used. Batteries should be replaced after half specified (from the battery manufacturer) lifetime for safe operation. Batteries purchased through the manufacturer of the battery backup have a lifespan (from the battery manufacturer) of between 10-12 years with recommended replacement after 5-6 years.

The unit must be de-energized during installation and connection.

  • Use the wiring that comes with the battery box to meet the wiring from the battery backup. See picture.

Wiring diagram and jumper

Alarms for tamper contact are connected in series and therefore the loop must be unbroken to the last battery box wiring. Jumper closes the loop on each wiring that goes from battery backup to battery box and in order for an alarm to be given on the tamper connector in the battery box, a yellow jumper on wiring must be cut. Do not cut the jumper on the last wiring in the battery box, as sabotage alarms will not be given in any connected battery backup or battery box.

Tamper switch when using battery box(-es)

If one or more battery boxes have been connected to the unit, the tamper switch must be connected in series in order for alarms from all units to be given. It is important that the series connection ends at the last tamper contact. The series connection must start in the battery backup unit and return to the last battery box.

All tamper contacts must be in series for everyone to be part of the alarm chain. Therefore, the yellow cable that is in the jackable connector must be cut on all connecting cables, except the last on. The cable must not be cut on the last connection / battery box.
