After first system start-up, check that battery temperature is displayable (press and simultaneously on the display – it reads NV (not valid) if incorrectly installed). A battery capacity test is recommended after the electric installation.

NOTICE!

If for any reason the start-up procedure is interrupted, wait for the display to show the step 4 message: “Stop charge DC capacitors : YES” and repeat procedure from there.

CAUTION!

Do not close the MCCBs in the Battery Breaker Box unless the display reads: “Close MCCB” - otherwise the UPS may be damaged. If the display reads “DC capacitor charge error”, do not close MCCB.
