Machine and Circuit Protection

Power Source is protected against overheating, overload
and accidental short-circuits.
If the machine is overheated, the thermal protection
circuit will decrease the output current to 0. The thermal
protection indicator [3] will turn on.
The Power Source is also electronically protected
against overload and accidental short-circuit. The
overload and short-circuit protection circuit automatically
reduces the output current to a safe value when it
detects an overload.
Transport & Lifting
Falling equipment can cause injury and
damage to unit.
During transportation and lifting with a crane, adhere to
the following rules:

Power source does not include the eye bolt which
can be used to transport or lifting the machine.

To lift use of suitable lifting equipment capacity.

To lifting and transport use a travers and minimum
two belts.
