2.4.1 UPS start-up

CAUTION!

Make sure all cable connections are in place prior to first start-up.

NOTICE!

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: “Insert fuse or close MCCB” – otherwise the UPS may be damaged. If the display reads “DC capacitor charge error”, do not close MCCB.

Call for assistance.

WARNING!

If “Autostart” is active the UPS will start automatically after step 9 (with a 1-minute delay)
