SR100Hi Series - 100W DC UPS
6. CONNECTION AND INITIAL TESTING
1. Check input and output voltages of system, ensure that they match the equipment. All loads should be isolated.
2. Check polarity of all wiring. Place temperature sensor probe near or on baeries.
3. Plug in ac input and turn power on. Both LEDs will light up aer approx. 4 sec, “BATT OK” LED will go out aer another 10 secs
(since there is no baery connected). DC output voltage should appear at both load and baery outputs (ensure screws are
ghtened down on the connector block).
4. Turn o input power.
5. Connect baery.
6. Check that ELCB (internal electronic circuit breaker) closes by shorng together the BATTERY –ve and LOAD –ve terminals for
about 2-3 sec. You will hear a relay operate and both LEDs will light up. If this does not happen, there is a fault in the wiring or
the internal baery protecon fuse is ruptured (see Note 2 below). The baery voltage will then appear at the load terminals
and the “BATTERY OK” relay energises. The “POWER OK” LED stays on for about 30 seconds.
7. Connect load wiring to LOAD+ and LOAD- terminals. Check that the load does not exceed 110% of the unit. Any peak loads which
are > 110% must be connected to the B+ and B-terminals.
8. Turn on ac power.
9. Aer the baeries are fully charged, check that the baery connues to power up the load when the input power is turned o.

Normal Normal System Normal: AC power is on, PSU output is OK, baery circuit is OK and baery voltage is > V Baery
Low.
Normal Normal Battery detection test imminent (LED begins flashing prior to test ).
Normal Alarm
System AC power is on, PSU output is OK but either:
1. Internal baery fuse has opened (only if baery has been reverse polarity
connected), or
2. Baery circuit open - baery missing, or fuse / circuit breaker / wiring fault.
Alarm Normal Either AC power has failed, or PSU has failed.
Baery system is OK
Alarm Alarm AC Power is o / DC has failed and baery has discharged to < V Baery Low, unit will connue delivering
baery current unl low level iniates ELVD.
Alarm Alarm AC Power is o / DC has failed and ELVD has acvated and disconnected baery from load. Residual
current drain on baery following ELVD <1 mA.
Normal Normal Baery Condion Test is in progress: LEDs ash alternately
Normal Alarm Baery Condion Unserviceable: failed to maintain terminal voltage during baery condion test
Please note that the last three conditions apply only if the battery condition test option is enabled.
