WARNING
Risk of injury from electricity
Double-check that the power is turned off.
Disconnect the machine from the power supply.
ATTENTION
Electrostatic charging may cause damage to equipment!
Work on the machine is ONLY permitted while wearing the antistatic
armband.
Handle the PCB only by its edges.
Do not push the PCB over a surface.
Checking the power
1.Open the control cabinet, the key for which is included with the machine.
2.Check whether LED (1) is lit up.
If LED (1) is NOT lit up, there is no power.
3.If LED (1) is still lit up, turn off the power, 2 Work preparation, p. 4.
