External inspections, tests Test values, comments, remedy
Test the ambient conditions
- Effectiveness of the ventilation system and
heating of operating space
- Room temperature, relative humidity, aggres-
sive air components, dust
Accessibility, minimum distances Escape routes, clearances
Visual inspection of covers and jacket-
ings Damage that adversely affect the type of protec-
tion, such as:
-
Missing parts
- Locking of doors
- Paintwork damage
Inspections Remarks
Condition of jacketing, attachment,
cover Repair if necessary, replace housing parts, clean
soiling and fix the fastenings, observing the in-
stallation manuals in doing so
Check for corrosion traces
- Repair damage with a suitable FZ791N
touch-up stick. For more significant damage,
grind, clean (e.g. with white spirit,
spot-removing spirit or universal thinner) and
then paint
- Check the operating conditions and ambient
conditions
Ventilation/traces of a rise in tempera-
ture Ensure clearance in front of ventilation inserts,
take suitable measures
