Connect as the picture shows; - possibly incoming controlled - incoming mains phase to terminal T2 on isolation switch, - incoming zero to terminal T1. - protective ground to terminal "PE".

For maximum safety, always disconnect from the mains before installation and service. Connect a load disconnector (circuit breaker) to the incoming cable from the mains. Place it easily accessible and label it clearly. With a load disconnector installed, incoming voltage can be easily interrupted during service and function tests.

Incorrect charging voltage (over/undervoltage), aged battery - when the battery should be replaced, or non-functioning inverter to 14. Alarm - contact NO and CO.

Time delay from direct to 10 hours delay in the following steps; (3s,3,15, 30min,1,2,4,10h) to circuit board terminal 12 . The time delay is set to SW1 according to Chart. Alarm - contact NO and CO.

In the event that fixed power supply is not present / not connected, the UPS can, to ensure function, be started with the help of fully charged batteries.

Follow the steps below to start the device in battery mode.

The batteries are valve-regulated maintenance-free 10-12 year batteries especially suitable for UPS operation with high short-term power consumption. Automatic fuse for battery protects against possible internal short circuit. The batteries are protected from overload by the inverter through electronic current limitation. The batteries are protected against harmful deep discharge so that all current consumption ceases when the battery voltage falls below a critical value (19 V). Only returning mains and thereby power from battery chargers overrides deep discharge protection. The batteries are also protected against "boiling-gassing" due to overcharging, by being disconnected from the charging current.

The batteries are charged to 27.3V final voltage under current limitation to achieve optimal service life at room temperature +20°C—+25°C. The charger is overcurrent and short circuit protected and also protects the batteries from overcharging/high charging current.

Electronic current limitation and overtemperature protection as well as automatic shutdown in case of heavy overload or short circuit after 3-5 seconds according to UPS STANDARD EN62040-1-1. The inverter is thus short-circuit protected.

As standard, the unit includes a self-test system (STS) that continuously monitors all functions in the system.

The self-test has three different parts:

1. Battery charging. An alarm is given in case of over- or under-charging. Undervoltage is only indicated if the charger for charged batteries does not provide the correct charging voltage. No false alarms when the batteries are recharged after a power outage, as the battery voltage is naturally low. Alarms are indicated by 3 red blink on the LED on the front panel at the same time that a self-diagnosis alarm is set. In case of overvoltage, the charge is disconnected from the batteries to prevent them from starting to "boil-gas". In case of overvoltage, 4 is given red blink on the LED on the front panel at the same time that a self-diagnosis alarm is set.

2. Alarm for aged battery. The capacity or aging of the batteries is tested regularly (every week). If tests show that the current battery capacity has fallen below 80% of the original rated capacity, an alarm is given to warn that the batteries need to be replaced. The reliability of the reserve operation is hereby tested in accordance with the established dimensioning requirements for the desired reserve operation time in battery operation. Batteries that have lost 20% of their capacity or more accelerate aging. They should therefore be replaced. This limit is defined as the life of the battery. In the event of an alarm for an aged battery, 5 is given red blink on the LED on the front of the cabinet at the same time as the self-diagnosis alarm is set.

3. The inverter test runs over an internal test load corresponding to the rated power, at the same time as a battery aging test. (Every week). This ensures that the output voltage is sufficient in UPS operation under load. In case of inverter failure, 7 is given red blink on the LED on the front panel (possibly additional blinks in the event of several alarms) at the same time that a self-diagnosis alarm is set.

During alarm self-diagnosis, the alarm contact switches to contact between NO-CO on 14.

An alarm is given when:

The alarm occurs after a period of power failure (= delayed power failure alarm), when the remaining battery capacity in battery operation falls below a pre-set level. In the event of a low battery voltage alarm, the alarm contact switches to contact between NO-CO on terminal 13. Indication with LED on front panel with 6 red blink.

During normal mains operation, the LED on the front panel is constantly lit. In the event of a mains failure, the inverter starts in battery operation, whereby the LED flashes 1 flash orange because when the time for any set time delay of mains alarm occurs, LED 2 flashes orange. In the event of an alarm mains failure, the alarm contact switches to contact between NO-CO on terminal 12.

During normal mains operation, the LED on the front panel is constantly lit. In the event of a mains failure, the inverter starts in battery mode, whereby the LED flashes 1 green flash. In the event of an alarm mains failure, the alarm contact switches to contact between NO-CO on terminal 17.

The inhibit function is not used in this application and is therefore bypassed from the factory.
