2.2.2 Circuit breakers
a) Main circuit breaker QF1
Circuit breaker QF1 interrupts the 3
phases, which power the hydraulic motor.
If the motor requires excessive power, the
circuit breaker activates and push-button
(F) - START is released. For safety
reason, the power supply to the motor is
immediately interrupted. After having
located and repaired the problem causing
this interruption, reset the circuit breaker
by pressing the push-button (F) START.
At the factory, the breaking current is set to
2.5 amperes.
Designation Description

D Power out connecting terminal
E Test push-button
F Reset button
b) Circuit breaker QF2 (2 Amps)
Circuit breaker QF2 protects the two
phases, which power the transformer.
Should the latter require excessive power
(>2 Amps), the breaker activates and lever
(B) flips down.
The power supply to the transformer is
immediately interrupted to avoid material
damages.
After having located and repaired the
problem causing this interruption, reset the
lever (B) of the circuit breaker.
