Operating envi -
ronments
Transport, storage or operation of the charger outside the stipulated area will be deemed
improper. The manufacturer shall not be held liable for any damage arising from such us -
age.
Ambient temperature range:
- during operation: -10 °C to +40 °C (14 °F to 104 °F)
- during transport and storage: -20 °C to +55 °C (-4 °F to 131 °F)
- recommended temperature range during charging: + 4 °C to + 40 °C (+ 39,2 °F to +
104 °F)
Relative humidity:
- up to 50 % at 40 °C (104 °F)
- up to 90 % at 20 °C (68 °F)
The surrounding air must be free from dust, acids, corrosive gases or substances, etc.
Can be used at altitudes up to 2000 m (6561 ft.)
Explanation of
the term "duty cy -
cle"
Duty cycle (D.C.) is the proportion of time in a 10-minute cycle at which the device may be
operated at its rated output without overheating.
NOTE!
The D.
C. values specified on the rating plate are based on an ambient temperature of 40°C. If the
ambient temperature is higher, either the D.C. or output must be reduced accordingly.
Example: Welding at 150 A at 60% D.C.
- Welding phase = 60% of 10 minutes = 6 minutes
- Cooling phase = remaining time = 4 minutes
- After the cooling phase, the cycle begins anew.
If the device is to be continuously operated without stopping:
look in the technical data for a D.C. value of 100% for the reigning ambient tempera -
ture.
Reduce the output or amperage in line with this value so that the device can remain in
use without observing a cooling phase.
