21 Safety Internal arc classified IAC AFLR according to the IEC Annex A UniGear is in full accordance to all the five criteria: 1. The doors of the switchboard must remain closed and no opening of the cover panels must occur; 2. Any part of the switchboard which may be hazardous for personnel must not be ejected; 3. No holes must appear in the external housing of the switchboard in any parts accessible to personnel; 4. The vertically and horizontally arranged fabric indicators placed outside the switchboard must not get burnt; 5. All the switchboard earthing connections must remain effective.
