What to do if Er16 appears during the parallel installation test of LEGRAND Daker DK 4.5 kVA?

  Michael WarrenAug 11, 2025
  If an Er16 error appears during the parallel installation test of the LEGRAND UPS, it means there's a parameter setting conflict between the UPS units. Repeat the process described in the “parameters check” and ensure that the common settings are the same for each unit. Process test 1.1 and check each parameter to ensure the settings are the same between each unit.

What to do if Er08 appears on LEGRAND Daker DK 4.5 kVA?

  An Er08 error on the LEGRAND UPS may appear due to a few reasons. First, the output voltage difference between units might be higher than 1.0Vac during parallel system startup. Check the inverter output voltage independently for each unit and calibrate units with abnormal output voltage. Second, there may be improper installation or a parallel system communication failure. In this case, check the parallel setting and repeat the Er-21 checks.

Why does Er17 appear on my LEGRAND Daker DK 4.5 kVA?
- D
  Diane HernandezAug 25, 2025
  The Er17 error on your LEGRAND UPS can occur for a couple of reasons. It could be that two or more units have the same ID number in a parallel system. Alternatively, the parallel function might not be enabled, but the ID number isn't set to 01 for a single unit. To resolve this, change the ID number setting, or set the ID number to 01 if using a single unit.

How to fix Er34 error on LEGRAND Daker DK 4.5 kVA?

  The Er34 error on a LEGRAND UPS indicates that new UPS version unit(s) are paralleled with older version unit(s). To resolve this, use the “UPS Setting Tool” software to enable special function flag #8. This makes the new version compatible with the old one.

What to do if LEGRAND Daker DK 4.5 kVA UPS shows Er27?
- A
  Andrew MillerSep 5, 2025
  The Er27 error on the LEGRAND UPS means that the UPS is not working in “Normal Mode”. Since “ECO Mode” and “Frequency-Converter Mode” are not supported for parallel systems, change the UPS setting to “Normal mode”.
