Power supply unit UPS, Or<strong>de</strong>r No. 77 3400 00<br />
3. Commissioning<br />
1. Insert the battery fuse between the batteries in the fuse hol<strong>de</strong>r (protection against total discharge<br />
during storage).<br />
2. Connect input and output terminal connections (refer to items 2.1 and 2.2).<br />
3. Switch on the input voltage (115 – 230 Volt).<br />
From now on, the connected nurse call system <strong>de</strong>vices are supplied with 24 V DC.<br />
4. The green LED "Power" is on due to the voltage at the terminal clamps.<br />
If the red LED "Battery low“ is on, the UPS function is not yet active<br />
(Place the bridging contact x – y).<br />
5. Now the power supply unit UPS is fully operational.<br />
4. Shutting the power supply UPS off<br />
1. Shut off the input voltage (115 – 230 Volt).<br />
2. Remove the UPS function acc. to item 2.3.1 (Remove the bridging contact), otherwise the load for<br />
the user circuits will be supplied through the battery until the total discharge circuit disconnects the<br />
battery.<br />
5. Service<br />
To ensure the safe function of the system, batteries should be replaced every 3 years - <strong>de</strong>pending on<br />
the ambient temperature (Refer to diagram 1, Item 6). After 3 – 5 years, the battery capacity has<br />
dropped to approx. 60%.<br />
6. Battery service life<br />
The power supply unit UPS comes with sealed, service-free and rechargeable led-gel batteries VRLA.<br />
According to the EUROBAT classification, these batteries have a useful service life of 5 – 7 years.<br />
This time, however, strongly <strong>de</strong>pends on the relevant ambient temperature. (Up to 20 °C: 7 – 8 years<br />
as shown in diagram 1)<br />
If the system will not be used for an exten<strong>de</strong>d period of time, the batteries should be fully charged to<br />
prevent a total discharge. (Refer to item 7 "Storage") After the charging process has been completed<br />
the power supply unit has to be disconnected from the mains supply and the battery fuse (un<strong>de</strong>r the<br />
left cover) has to be removed.<br />
