4.1. OBLIGATORY
Depending on ambient temperature, the power correction described in IC-G-B-00-001e should be made.
4.2. RECOMMENDED
It is advisable to regulate the engine power according to reachable values (below the shutdown-triggering
values) to avoid sudden shutdowns of the engine at facilities short of cooling.
The recommended regulations to be made with the signals of the minimum safety measures installed are shown
below.
