From 30 °C: Protection against overheating of the charger by automatic re-
duction of the power (derating)
From 45 °C: Only standard charging possible to increase battery life
From 70 °C: Power source switched off
Charging is not possible below 0 °C. Welding is conditionally possible de-
pending on the current level.
Two additional sensors directly on the power module
the temperature indicator lights up and „hot" is shown on the display
neither welding nor charging is possible until the temperature indicator goes
out (when the battery has cooled down)
