14.6. Changing the DC and AC surge arresters

These units are equipped with type 2 surge arresters in the DC and AC connections.
In the event of an overvoltage surge, it is possible for the DC surge arrester or the AC surge arresters and its
protection fuses to be damaged.
The damage of the overvoltage surge arresters is indicated with a warning. The warning indicates a surge arrester
fault, but it is necessary to carry out a visual inspection to know which surge arrester is damaged, and a verification
of the condition of the AC surge arrester protection fuses.
To order replacement surge arresters please contact Ingeteam.
The surge arresters can be replaced partially or entirely. The modular system of the AC and DC surge arresters used
allows to replace only the damaged cartridge if desired. However, the surge arrester manufacturer recommends
replacing the entire surge arrester.
To replace these cartridges, proceed as follows:
1. Remove voltage as explained in section
2. Open the lower compartment.
3. The unit triggers an alarm when any of the cartridges fail, so you must inspect them to see which
cartridge is damaged. To do this, see the visual instructions on the arresters (green/red). The cartridges
with indications in red are those that must be replaced.
