• Charge status too low.
• Battery fuse has failed.
• Battery not correctly connected.
• Battery is defective.
• Battery is too old, and must be replaced.
3. Commissioning
1. Connect input, output and battery terminal connections (refer to items 2.1 and 2.2).
2. Switch on the input voltage (115 – 230 Volt).
From now on, the connected nurse call system devices are supplied with 24 V DC.
3. The green LED "Power" is on due to the voltage at the terminal clamps.
If the red LED "Battery low“ is on, the UPS function is not yet active
(Place the bridging contact x – y).
4. Now the power supply unit UPS is fully operational.
4. Shutting the power supply UPS 60 off
1. Shut off the input voltage (115 – 230 Volt).
2. Remove the UPS function acc. to item 2.3.1 (Remove the bridging contact), otherwise the load for
the user circuits will be supplied through the battery until the total discharge circuit disconnects the
battery.
5. Service
To ensure the safe function of the system, batteries should be replaced every 3 years - depending on
the ambient temperature (Refer to diagram 1, Item 6). After 3 – 5 years, the battery capacity has
dropped to approx. 60%.
6. Battery service life
The batteries connected to the power supply unit UPS 60 are sealed, service-free and rechargeable
lead-gel batteries VRLA. According to the EUROBAT classification, these batteries have a useful
service life of 5 – 7 years. This time, however, strongly depends on the relevant ambient temperature.
(Up to 20 °C: 7 – 8 years as shown in diagram 1)
If the system will not be used for an extended period of time, the batteries should be fully charged to
prevent a total discharge. (Refer to item 7 "Storage") While the system is not used, the battery fuse
has to be removed to prevent total discharge.
