The electronic motor starter must be replaced after a short-
circuit occurs. It is strictly prohibited to keep using it!
Depending on the installation situation and the maximum ambient air
temperature, it may be necessary to derate the maximum rated operational
current.
Derating is based on the following installation situations:
• separate mounting,
• connected in series with 30 mm clearance,
• without clearance.
